Isabelle Bienen is a junior at Northwestern University studying Social Policy with minors in Environmental Policy & Culture and Legal Studies. The focus of her NWNL research and blog series this summer is on the U.S. Clean Water Act: its history, purpose and status today. The subject of this first blog in her series is on its creation and potential to solve issues in our Mississippi River Basin case study watershed.

Introduction

The Clean Water Act was created by the U. S. Congress to ensure that those in the U.S. have access to safe drinking water. This blog series will highlight the threats that spurred the creation of this act (citing specific issues in NWNL case-study watersheds); a definition of its regulations; and an analysis of its implementation and implications. Below is the first post in this series which outlines how this Act came to be. It continues to specifically depict existing threats in the Mississippi River Basin (a NWNL case study watershed) that helped shape the Act and those that are addressed in the Act. The second blog in this series will detail existing threats and those addressed by the Act that are in the other 2 NWNL North American case study watersheds: the Pacific Northwest’s Columbia River Basin, and New Jersey’s Raritan River Basin.  The third blog will discuss general health threats across the U.S. that also clearly highlighted the need for the Clean Water Act.

The Birth of the CWA

The Clean Water Act was adopted in 1972 due to an overwhelming response from local governments, state officials and the general public over their growing dismay for poor water quality. The alarm prompted by photographs of a 1969 Cuyahoga River fire in Cleveland, Ohio, is often considered the tipping point for the creation of this Act. An investigation conducted that year by Cleveland’s Bureau of Industrial Wastes stated that the fire was caused from “highly volatile petroleum”1 with a “low flash point at the end of the railroad trestle bridges.”1 The flames were recounted to have climbed as high as five stories. The previous year, Cleveland residents passed a $100 million bond issue to finance river protection and cleanup efforts, yet there was no success due to a lack of any government controls to protect the environment. This grave situation indicated the need for federally-implemented water protection, as the Clean Water Act eventually would provide.

The Mississippi River Basin’s Clean Water Issues

The Mississippi River Basin drains into 31 states and 2 Canadian provinces, supporting 60% of North American birds and 25% of North American fish.2 Nonpoint sources of pollution from the basin’s manufacturing, urbanization, timber harvests and hydrologic modifications have contributed to water contamination by PCB’s, DDT and fecal bacteria. A buildup of excess nutrients spurring algae growth and producing dead zones comes from nitrogen and phosphorus used in crop fertilization. The many locks and dams along the length of the Mississippi River have caused the loss of natural filtration of pollutants by coastal wetlands.3 This body of water was completely unregulated for pollutants, causing a wide range of problems that greatly impacted marine life and the surrounding environment.

One of the biggest problems in the Mississippi River Basin is the nonpoint source runoff of agricultural chemicals that feed algae blooms which creates large hypoxic dead zones. These dead zones emerge from the Mississippi River Delta and flow into the Gulf of Mexico, reportedly covering around 6,000 to 7,000 square miles from the inner and mid-continental shelf and westward into the upper Texas coast.4 This hypoxia has killed and displaced a variety of marine species, and the freshwater species depend on these displaced resources.5 Still, today, agricultural runoff from midwestern farms flows into the Gulf. Due to steadily increasing levels of flooding since the 1930’s, as well as an increase in the amount of paved surfaces in these areas, greater amounts of synthetic fertilizers, animal waste and other nutrient pollution are running off into these waters at an accelerated rate.5 According to Mother Nature Network, “The biggest overall contributor to the Gulf of Mexico’s dead zone is the entire Mississippi River Basin, which pumps an estimated 1.7 billion tons of excess nutrients into Gulf waters each year, causing an annual algal feeding frenzy.”5

Additionally, point-source pollution from a high number of petrochemical plants between Baton Rouge and New Orleans has negatively impacted the Lower Mississippi River and Delta. This stretch of the Mississippi River is known as “Cancer Alley” due to numerous reported cases of cancer occurring in small rural communities along the river.6 In 2002, the State of Louisiana reported the second highest numbers of deaths caused by cancer in the United States. The national average death-from-cancer rate is about 206 per 100,000; while Louisiana’s rate is ten times that at  237.3 deaths per 100,000.6

The Mississippi River Basin, prior to the CWA, is clearly in need of regulation as highlighted through the condition of this water system. The following blog post will further discuss the status of NWNL River Basins prior to the CWA – specifically in the Columbia River Basin and the Raritan River Basin.

Surprisingly Similar: Deer and Elephant

By Bianca T. Esposito, NWNL Research Intern
(Edited by Alison M.  Jones, NWNL Director)

NWNL research intern Bianca T. Esposito is a Syracuse University  senior studying Biology and Economics. Her summer research was on the nexus of biodiversity and water resources. She already has 3 NWNL blogs on African and N American watershed species:  Wild v Hatchery Salmon; Buffalo & Bison; & Papyrus & Pragmites.

INTRODUCTION

This blog compares Africa’s savannah elephant (Loxodonta africana) to the N. America’s white-tailed deer (Odocoileus virginianus) in North America’s eastern United States. They present unlikely, but strikingly interesting comparative behaviors and impacts within their watersheds.  

In the Pliocene Era, elephants roamed and trumpeted their presence across the planet. Today they are a keystone species in African watersheds, including the Nile, Mara and Omo River Basins. Yet these giants are increasingly vulnerable to human poaching, hunting and destruction of habitat and migratory corridors. As a result, African savannah elephants are categorized as a “vulnerable” species.

In North America, white-tailed deer (also called Virginia deer) are present across the continent from the Atlantic Coast’s Raritan River Basin to the Pacific Coast’s Columbia River Basin. These nimble jumpers probably came to N America in the  Miocene Era as browsers competing for their niche with American rhinos. As they wheeze, grunt and bleat their presence today, they have few natural predators remaining, other than car collisions. Deer in the eastern US are a “Least Threatened” species – while Columbian white-tailed deer in Oregon’s Lower Columbia River Basin are “Near Threatened”.  

Jones_090629_NJ_1137.jpgWhite-Tailed Deer , Upper Raritan River Basin, New Jersey

North American male deer stand at 6-7 feet and weigh 100-275 pounds (¼ of a ton, the weight of a baby elephant).  In contrast, full-grown elephants stand at 11 feet (twice as tall as deer) and weigh up to 13,000 lbs (6.5 tons). Yet despite these huge size differences, these 2 species impacts on watershed forests are quite similar. As herbivores, both threaten and alter their habitats’ vegetative diversity, growth and regeneration.

VEGETATION & FOREST INTERFACE

Elephants alter their watersheds by converting woodland to shrubland. Elephants consume large amounts of vegetation allowing growth of plants previously blocked from the sun. However the benefit of increasing plant diversity is countered by the destruction elephants cause while browsing their way through watersheds. They remove trees, trample grasses and compact the soil. This limits forest regeneration since seedlings cannot grow and their trails cause soil erosion.

Similarly, deer today are increasingly damaging forest vegetation due to their soaring populations. In the Raritan River Basin, impacts of high deer populations have resulted in habitat loss for birds and other animals that rely on vegetation for protection. Thus, native species are decreasing and could eventually disappear locally.

HUMAN INTERFACE

Another similarity both species face is that of negative interactions with humans. Elephant and deer both damage farmers’ crops.  Elephant contact with humans continues to increase as they lose their traditional habitats due to human infringement and development. Increased development has also led farmers to further transgress into what was elephant rangeland or migratory corridors. In following and browsing along their ancient pathways and territories today, elephants can trample crops and even kill people. Those elephants are often killed in retaliation. In Tanzania’s Serengeti District, the effect of elephants raiding crops means a bag of maize can be locally more valuable than the cost of building a classroom or tarmac road.

In America, deer find an ideal environment in urban and suburban areas with their mix of ornamental shrubs, lawns and trees.  Since deep forest vegetation is too high for them, deer browse along the “edge habitat” which also provides easy access to suburban yards.

With the loss of wolves, bears and cougars, deer have had a lack of predators, causing their populations to soar. Now their biggest predators are human hunters and car accidents which cause deer and human fatalities. As well, human health impacted by deer that browse in the woods, meadows or dunes with ticks carrying Lyme disease (Lyme borreliosis). Lyme disease can be lethal, or at the least debilitating, for humans, livestock and pets.

For elephant and deer, interaction with humans is not beneficial for either species. Sadly, given less space for the exploding human race, these fateful interactions will only increase.

WATER INTERFACE

The spread of human settlements, agriculture and livestock farming have replaced elephants’ natural habitats. Clearing of those traditional lands disturbs and decreases water volume in their rivers and lakes. Yet, when elephants were there, they created water holes which increased water availability for themselves and other species. Simultaneously, humans are increasing their consumption of today’s decreasing water and other natural resources.  

This scenario is dramatically playing out in Kenya’s Mara River Basin. In the Mau Forest highlands, human deforestation has depleted flows of source tributaries of the Mara River, a lifeline to the Maasai Mara National Reserve and Tanzania’s Serengeti National Park. In turn, lowered water levels downstream have increased temperatures and disrupted local rainfall patterns. Thus the human takeover of the Mau Forest has chased out the elephant and disturbed downstream ecosystems, which in turn will contributed to decreases in wildlife populations and thus park revenues from tourism.

Elephants have direct impacts on water sources and availability since they are a “water-dependent species.” When water is scarce, they dig in dry river beds to provide water for themselves, other animals, and humans. Additionally, elephants migrate to find water – even if only via artificial, supplementary water points. More research is needed, but water availability may become a useful tool for regulating elephant distribution and managing ecological heterogeneity.  Yet an abundance of artificial water should be avoided in conservation areas where the presence of elephant would cause vegetation degradation.

Jones_090930_K_0584.jpgAfrican Elephants crossing the Mara River, Mara Conservancy, Kenya

Deer, unlike elephants, have a more indirect impact to water resources. Their impacts are more about quality of water than its availability. The nutrients and pathogens excreted by white-tailed deer become water pollutants in nearby streams and groundwater, especially during in storm runoffs.  Deer waste dropped in and along streams in the Raritan River Basin produces greater pathogenic contamination than cattle manure deposited away from streams.

HUNTING AS A WAY TO REDUCE HUMAN-WILDLIFE CONFLICTS

Hunting is a controversial solution to controlling these species’ threats of ecosystem degradation and human conflict. Hunting elephant to counter their negative impacts has much greater negative consequences than hunting deer. Elephant poaching for  lucrative ivory profits became such a serious threat that elephants became listed as an Endangered Species. While a 1989 ban on international ivory trade allowed some populations to recover, illegal ivory trade still occurs and threatens elephant populations. Thus, shooting elephants marauding crops and killing farmers is not an option – thus the search for other means to controlling elephant degradation.

After elephants devour all vegetation in an area or during droughts, they migrate. However, that puts them face to face with today’s man-made fences and trenches built to stop elephants, as well as with new communities and farms. Thus Kenyan conservancies, International Fund for Animal Welfare,  Addo Elephant NP, Sangare Conservancy and other groups began creating “protected elephant corridors.” Such corridors provide elephants safe migratory paths where they don’t disturb humans.

Jones_180129_K_7661.jpgRanger at the entrance gate to Sangare Conservancy, Kenya

Deer hunting however is viewed  by many as a positive means to control over-abundant deer populations destroying gardens and forests. In rural regions, deer are still hunted for food and sport which helps save forest saplings from deer browse. But that removes only a limited number, and there have been traditional limits on deer hunting. Along Mississippi’s Big Black River, the state still restricts  killing year-old bucks and any deer hunting during floods. Many such restrictions are being loosened today to help counter the rapid growth of deer populations. As well, to reduce deer browse and car collisions, some suburbs hold carefully-organized, targeted hunts by licensed “sharp-shooters,” and the venison is harvested for homeless shelters. Suburban methods to combat deer intrusions also often include installing 8-foot tall fences to protect gardens, landscaping and critical ecosystems.

FOREST IMPACTS

Elephants’ foraging creates open habitats for other species. However, browsing of resulting mid-successional species by elephants and other species can stop regrowth of trees and forest. “As go the elephants, so go the trees.” This issue is similar to deer browsing on soft-leaved saplings in N. American forests that preventing the growth of future forests.

Yet elephants compensate for their heavy vegetative consumption.  More than a dozen tree species depend on forest elephants for to spread their seeds. This type of seed dispersal occurs via each elephant’s daily  200-lb. dung droppings, thus ensuring survival of vegetation. Another benefit of creating open spaces by altering and removing trees is the opportunity for greater faunal diversity. Elephants uproot and fell trees and strip bark; but in this process, they break down branches which provides access to food for smaller wildlife.

TZ-ELE-215.jpgHerd of African elephants with newborn, Lake Manyara National Park, Tanzania

All this change created by elephants creates “a cyclical vegetational seesaw of woodland to grassland and back to woodland.” As debris of trees felled by elephants shields pioneer grasses and shrubs from trampling, deep-rooted perennial grasses can grow. These grasses attract grazers to the area, while the browsers leave. When the woodlands regenerate, elephant number will return, followed by browsers.  

Deer, unlike elephants, are non-migratory however, and thus they don’t spur cycles of regeneration. Therefore, watersheds with deer-infested forests face ongoing degradation. Today’s soaring numbers of deer prevent any chance of forest recovery from their constant browsing. Deer also displace native wildlife, which furthers the cascade of ecosystem degradation. When a forest loses trees, there is less water recycling  since trees produce and move rain downwind to other terrestrial surfaces.  Water retention in a forest is also related to presence of ground cover – also eaten by deer – which decreases stormwater runoff and downstream erosion in floodplains or wetlands. A lack of ground cover causes inland forests and downstream areas to become arid and potentially a waste land. The deer do not produce compensatory benefits that elephant produce.

CONCLUSIONS

Elephant and deer each have increasingly negative impacts on watershed vegetation and human communities. However a big difference exists in effective stewardship for controlling these species. In Africa, elephant numbers (2007-2014) have dropped by nearly a third, representing a loss of 144,000 elephants.  Begun in 2014, the Great Elephant Census (GEC) accounted for over 350,000 savannah elephant across 18 African countries and states the current yearly loss at 8 per cent. Tanzania, having one of the highest declines, and Mozambique have lost 73,000 elephants due to poaching in just five years.

However deer populations have exploded.  In 2014, US deer populations across the United States were estimated at over 15 million. In New Jersey, there are approximately 76-100 deer per square mile; yet a healthy ecosystem can support only 10 deer per square mile.  These high densities of deer are decimating US forests.

Making elephant poaching illegal and banning ivory trade has saved elephant populations in Africa. But in N America further controls of the growing population of deer is badly needed. The most obvious step towards this goal would be to remove deer hunting restrictions – the very opposite of Africa’s stopping the hunting and poaching of elephants.

On both continents, immediate solutions are critical if we are to protect our forests and water supplies – critical natural resources of our watersheds – from degradation being increasingly incurred by both species. Elephants consume vegetation and degrade areas of abundant water; while tick-carrying deer contaminate water with their excrement and threaten the future of our forests. One could summarize the consequence of too many deer as “No Forests – No Water” – and the consequence of losing elephant as “No Elephants – No Water.”

Small but Critical / Our Invertebrates

This blog contains several references to invertebrates in northern Kenya’s Lake Turkana Basin, the arid terminus of Ethiopia’s Omo River and world’s largest desert lake.  Within this “Cradle of Humankind,” species continually adapt, as explained in our NWNL Interview with Dino Martins, entomologist at Turkana Basin Institute.

Animal species in our watersheds quietly enhance and protect the health of our water resources.  Yet, rarely do we give our fauna – from wolves to woodpeckers – enough credit. This is especially true of our smaller invertebrate species, which include butterflies, bees, beetles, spiders, worms, starfish, crabs and mollusks.  Invertebrates span the globe in habitats ranging from streams, forests, prairies, and deserts to lakes, gardens and even glaciers. Sadly, these unsung heroes are often called “pests.”

Jones_031026_ARG_0471.jpgInvertebrate atop Perito Moreno Glacier, Argentina

Invertebrates are defined by their lack of backbone, yet ironically, they are “the backbone” of our land- and water-based ecosystems.  Comprising 95-97% of animal species, they keep our ecosystems healthy; and although spineless, they are a critical base of the food chains for many species, from fish to humans.  Fly fishermen carefully study the macro-invertebrates in their streams and rivers before choosing lures of mayflies, worms and caddisflies that appear in different stages, in different seasons, on different streams.

Invertebrates benefit our world in numerous ways:

  • pollination – of fruit, grain, and native plants
  • seed dispersal – a job shared with birds  
  • recycling of waste, nutrients and food for other species, including humans
  • production of nectar and honey as a healing resource and immunity booster
  • purification of water and the environment
  • creation of reefs by mollusks, especially oysters
  • being useful research specimens (Think of fruit flies in biology class…)

One of the most valuable contributions of invertebrates is the pollination of our orchards and fields by bees and bumblebees.  Without this, human food sources would be quickly and greatly diminished. Bees also pollinate riverine vegetation needed to retain water and prevent erosion. It is as simple as “No bees – No vegetation – No water!”  

Jones_090615_NJ_0817.jpgHoney bee pollinating spring blooms in Raritan River Basin, NJ

Ancient and contemporary Mayans have known that invertebrates are the foundation of the living world. Thus mosaics of mosquitoes, still today in Guatemala, are the symbolic woven foundations of women’s huipiles (blouses).  Worldwide, mosquitoes and macro invertebrates provide food for other invertebrates, notably juvenile fish – locally called “cradle fish” – in northern Kenya’s Lake Turkana gulfs and bays.

However, Lake Turkana fish populations have been greatly reduced recently due to overfishing and upstream Ethiopian dams.  Fortunately, the Lake Turkana invertebrate bee population’s honey production has provided a needed alternative source of calories.  Fewer fish, combined with drought-afflicted livestock and maize, have led the Turkana people to turn to bee-keeping as their new livelihood.

Author Sue Stolberger describes another oft-overlooked role of  invertebrates in her Tanzanian guidebook. She explains that many invertebrates are “expert at natural waste disposal. Beetle larvae dispose of leaf litter. Maggots, blowflies and others play a role in the disposal of carrion; and dung beetles dispose of excrement, which cleans up the excreta and fertilizes the soil.”  [Stolberger, p 197.]

In tidal estuaries, purification of water by mollusks is much cheaper route to addressing pollution than governmental SuperFund Site cleanups.  Oysters very effectively filter our rivers and bays. Today the New York-New Jersey Harbor & Estuary Program is reintroducing oysters into the Hudson and Raritan Bays to clean those waters and stabilize their shorelines and riverbanks.  [See NWNL Blog on Oyster Restoration in Raritan Bay by NY-NJ Baykeeper]

Few people are aware of the endurance and numbers of invertebrates.  The dragonfly story is amazing. Known for accomplished gliding and crossing oceans, dragonflies form one of the world’s largest migrations.  Due to their large numbers, they’re among the most ecologically important insects and are voracious consumers of mosquitoes, worms, crustaceans and even small fish.  Kenyan entomologist Dino Martins explained to NWNL that dragonflies are also great bio-indicators of ecosystems’ health. The presence or absence of “different types of dragonflies and/or macroinvertebrates [that] tolerate different stream conditions and levels of pollution… indicates clean or polluted water.” [Utah State University]  

Jones_090906_NJ_1634.jpg

Shimmering dragonflies and damselflies, butterflies and even snails have inspired beautiful art, poetry and other creative expressions.  In Japan, generations of haiku authors have compressed the unique qualities of these special creatures into 17 concise syllables, as in this by Issa:

The night was hot… stripped to the waist the snail enjoyed the moonlight

                             —The Four Seasons:  Japanese Haiku.  NY: The Peter Pauper Press, 1958.

Even the descriptive names given to our butterflies evoke a sense of poetry: Pearl Crescent, Red Admiral, Question Mark, Mourning Cloak, Silver Spotted Skipper….  Seeing the opalescent Mother of Pearl Butterfly (Protogoniomorpha parhassus) and the electric Blue Pansy Butterfly (Junonia oenone oenone) in Kenyan forests could turn anyone into a lepidopterist and an artist.

Despite these valuable attributes, invertebrates are slapped at; often seen as bothersome and unwanted; and most dangerously, ignored in environmental policies and land use practices.  Sadly, we now have many at-risk species: from bumble bees to tiger beetles and butterflies. Caddisflies that live solely in one stream are becoming extinct. To understand their role in stream ecosystems, talk to a fly-fisherman or visit a riverside tackle shop.  

On land, herbicides are sprayed in fields and along our roadsides through the summer, killing large swaths of milkweed, the sole food of monarch butterflies.  In Michoacan Mexico, the winter retreat for all monarchs east of the Mississippi, illegal deforestation now leaves tens of thousands of monarchs frozen to death annually.  Their small pale carcasses silently pile up on the ground where there used to be dense oyamel pine forests protecting them from freezing temperatures.

Jones_040122_MX_0291.jpg
When frozen, monarchs fall to the ground, folding their wings as they die 

The biggest threat to invertebrates is the loss of native habitat to development and agriculture.  Native bugs, butterflies, beetles and bees need native wildflowers. Flying insects in the US Midwest now lack the succession of wildflowers since midwestern prairies have been reduced to mere fragments, called “remnant prairies.” In 2013, entomologist Dino Martins told NWNL, “Farmers need to understand why leaving a little space for nature isn’t a luxury, but a necessity for productive, sustainable agriculture.”  

The importance of wildflower habitat for invertebrates was publicized in the 1970’s by Lady Bird Johnson, wife of former President Lyndon Johnson, and actress Helen Hayes..  Now many municipalities, organizations and gardening groups are publicizing the importance of replanting native wildflowers (milkweed for monarchs!) and eliminating invasive species.  Farmers, land managers, environmental regulatory agencies, park managers and home gardeners need to become more aware. They can help protect the soil and water quality of our rivers, streams, ponds, wetlands in many ways.  Funding for that research is critical, as is promoting citizen-science training programs. We can all pitch in to weed out invasive species if we learn what to look for.

Jones_080810_BC_6882.jpgSignage identifying invasive species in British Columbia

Small critter stewardship is growing.  There is good news.  The use of “Integrated Pest Management” and reduction of pesticides and herbicides is spreading; awareness of the consequences of killing our invertebrates grows.  Commercial and small farmers are learning to supply water in their fields for bees so they don’t waste energy looking for rivers. The Endangered Species Act supports the many organizations resisting the overuse of chemicals and unregulated land development.  

  • NYC Butterfly Group uses citizen scientist to map NYC’s butterfly distribution.
  • Xerces Society for Invertebrate Conservation [www.xerces.org), begun in 1971 trains farmers and land managers to save forest, prairie, desert and river habitat for these invertebrates via newsletters, books, guidelines, fact sheets and identification guides.  
  • National Wildflower Research Center,founded by Lady Bird Johnson in Texas, preserves N. American native plants and natural landscape
  • BuzzAboutBees.Net  www.buzzaboutbees.net/why-are-invertebrates-important.html website offers in-depth facts and advice on bees and bumblebees, as well as books, advice on stings and best garden practices.

It is time for us all to identify and weed out invasive species; help monitor monarch migrations; support local land trusts preserving open space; and advocate for more wildflower preserves.  Baba Dioum, a Senegalese ecologist wrote, “In the end, we will conserve only what we love. We will only love what we understand. We will understand only what we are taught.”

50 Years of the Wild & Scenic Rivers Act

Written by NWNL Project Manager, Sarah Kearns
with Research by Jenna Petrone

An unspoiled river is a very rare thing in this Nation today. Their flow and vitality have been harnessed by dams and too often they have been turned into open sewers by communities and by industries. It makes us all very fearful that all rivers will go this way unless somebody acts now to try to balance our river development.” — Lyndon B. Johnson, on signing the US Wild & Scenic Rivers Act in 1968.1

Jones_171027_OR_6986McKenzie River, Oregon, Columbia River Basin

On October 2 this year, the US will celebrate the 50th anniversary of the Wild & Scenic Rivers Act established to preserve rivers with outstanding natural, cultural and recreational values in their free-flowing condition for the enjoyment of present and future generations.2

At the time of enactment in 1968, eight rivers were given the designation of Wild & Scenic Rivers: Clearwater, Eleven Point, Feather, Rio Grande, Rogue, St. Croix, Salmon, and Wolf. As of December 2014, this National System, under the Department of the Interior’s Bureau of Land Management, protects 12,734 miles of 208 rivers in 40 states and Puerto Rico. The total mileage of this system represents about .35% of US rivers, compared to the 17% of US rivers totaling 600,000 miles, that are currently dammed or modified by 75,000 large dams.3

While .35% is a shockingly small percentage, the official anniversary website reminds us to celebrate the Act’s accomplishments over the past fifty years. The growth from protecting only 8 rivers to protecting 208 rivers spanning 12,000 miles is a huge accomplishment. We encourage all to celebrate in order to look positively to the future when another 12,000 miles could be designated!

What exactly is a “Wild & Scenic River?”

Under this Act, Congress can designate a river under one of three classifications: wild, scenic, or recreational. A designated river can be a segment or stretch of a river, not only its entire length, and can also include tributaries. 

How does a river get classified?

“Wild” River Classification: Rivers (or sections of rivers) that are “free of impoundments and generally inaccessible except by trail, with watersheds or shorelines essentially primitive and waters unpolluted.”

“Scenic” River Classification: Rivers (or sections of rivers) that are “free of impoundments, with shorelines or watersheds still largely primitive and shorelines largely undeveloped, but accessible in places by roads.”

“Recreational” River Classification: Rivers (or sections of rivers) that are “readily accessible by road or railroad, that may have some development along their shorelines, and that may have undergone some impoundment or diversion in the past.”4

It is important to note that the type of classification doesn’t change the type of protection each river or segment receives! All rivers/segments designated under the Wild & Scenic Rivers Act are administered with the goal of protecting and enhancing the values that caused it to be designated to begin with. This protection is administered by federal or state agencies, which is provided through voluntary stewardship.5

Of the 208 rivers & river segments, 23 are located in NWNL’s US Case-Study Watersheds and Spotlights:  Columbia River Basin, Mississippi River Basin and California. Between now and the official October 2 anniversary, we will post several more blogs with photographs of many of these designated rivers.

How can you celebrate?  NWNL encourages everyone to support all of our rivers and freshwater waterways, particularly the ones protected under the Wild & Scenic Rivers Acts. Swim in your local recreational river; go boating; organize a “Bioblitz;” join your local river stewardship organization; and most importantly, talk to your friends and families about why our river are so vital to our country!  This interactive story map shows whether you live near a designated river or river segment!

The Great Giver: The Nile River

By Joannah Otis for No Water No Life (NWNL)

This is the 9th and final blog in the NWNL series on the Nile River in Egypt by NWNL Researcher Joannah Otis, a sophomore at Georgetown University. This essay addresses the human uses of the Nile River.  [NWNL expeditions have covered the Upper Nile, but due to current challenges for US photojournalists in Egypt and Sudan, NWNL is using literary and online resources to investigate the Lower Nile.]

The Nile River was vital to the lives and livelihoods of Ancient Egyptians and continues to play a significant role in modern Egyptian life. Egypt, as well as other countries in the Nile River Basin, rely entirely on this great river for fresh water. This reliance places great pressure on the river, especially Egypt’s extraction of the maximum amount of water it can according to international treaties.From aquaculture and fishing to drinking water and transport, Egypt uses the Nile for a wide variety of purposes. The Nile River also has considerable economic value since the Egyptian agriculture relies heavily on the Nile’s water. The human uses and values of the Nile River reflect its importance to the people who live along it.

A large portion of the water drawn from the Nile is for agriculture, a source of income for about 55% of the Egyptian population.2 In Ancient Egypt, farmers used a water-lifting device known as a “shaduf,” used to collect and disseminate water. This technology, developed around 1500 BCE, allowed farmers to irrigate their fields even during dry spells. It was so effective that the acreage of cultivable land expanded by 10-15%. Today, farmers use electric pumps and canals to transport water to their fields.3

Fish are a staple of the Egyptian diet and the fishing industry has thrived accordingly. However, unfortunately, overexploitation and high fishing pressures have stressed the natural fish populations. The river’s carrying capacity has been stretched to its limit and struggles to support the stocked fish. Such high stocking levels can result in poor water quality and an altered ecosystem.  To increase fish production, exotic species have been introduced to the Nile, but they have caused an imbalanced ecosystem and threatened native species. Illegal fishing continues to be a concern as well.4 

Compared to today, commercial fishing was of relative unimportance to the Ancient Egyptians. Although fish not consumed by the catcher were often sold for profit, trade of luxury goods and produce was a much more significant source of revenue. Nubia in particular was an important trading point as it provided ivory, slaves, incense, and gold, the riches that pharaohs and high society prized. Wadi al-Jarf was also a bustling trading town along the river. Since the Nile River flows to the north, boats could easily float downstream with their wares. At the same time, reliable southerly winds allowed vessels to sail upstream.5

For millions of years, the Nile River has continued steadily along its northward course. For thousands of years, it has given its people livelihoods and a precious source of water. Although excessive irrigation and overexploitation of fish threaten its flow, the Nile remains resilient. With proper care and environmental attention, the Nile can continue to thrive for years to come.

Lake Erie: A Solution to Vulnerability

By Judy Shaw, with Wil Hemker and John Blakeman for NWNL
(Edited by NWNL Director, Alison Jones)

Judy Shaw, professional planner and NWNL Advisor, and Wil Hemker, entrepreneurial chemist, are partnering with John Blakeman to promote prairie nutrient-retention strips as a proven way to protect Lake Erie’s water. They are encouraging schools and farmers in northwest Ohio to install demonstration strips and teach this effective means to stop harmful runoff from damaging our waterways. NWNL has documented this runoff problem in all its case-study watersheds and applauds this natural solution to chemical pollution of our waterways.

Imagine a very large body of fresh water supplying residents along 799 miles of shoreline with the very essence of their natural health. Lake Erie is such a vessel; carrying over 126 trillion gallons of precious water and serving millions of people in cities both in the USA and Canada. One such city is Toledo, Ohio. There, water from the Maumee River, which flows directly into the Western Basin of Lake Erie, provides fresh water to many in the region. Up to 80 million gallons of water is drawn from Lake Erie every day to supply Toledo and other municipalities with treated drinking water. 2

However, runoff from agricultural lands taints the water with phosphorous. In 2014 runoff caused extensive blooms of green algae, creating toxic microcystins – toxins produced by freshwater cyanobacteria, also called blue-green algae.3 This rendered the water on which the city relied as undrinkable. Today, four years later, continued flows of phosphorus-laden water still make this treasured natural resource vulnerable.

So what can be done? 

Many scientists have studied the problem. They’ve universally agreed that rainfall runoff from row-crop fields, suburban and urban land, and roadways is the root of the problem. As the City of Toledo rushes into a $500 million upgrade to its water treatment plant, the source remains completely uncontrolled.4

Fortunately, solutions to manage rainfall runoff pollution are at hand. 

Through the work of many dedicated Midwest scientists, it has been determined that the presence of tallgrass prairies and seasonal, agricultural “cover crops”5 can arrest the phosphorous and nitrogen that historically has streamed directly into feeder streams and large watersheds like the Maumee River Basin.

On the matter of cover crops, it is important to note that wheat is planted in closely-spaced rows. Non-row crops include hay and alfalfa, planted en masse, not in rows. Alfalfa, because it is grown as a crop and is harvested, is not generally regarded as a cover crop. Cover crops are seldom, if ever, “cropped,” or harvested. Instead they are killed, or die, and left on the soil surface. Generally, cover crops are not true cash crops in the sense of harvesting and marketing.

Ohio prairie researcher John Blakeman found that edge-of-field strips of perennial tallgrass prairies can absorb algal nutrients in storm-water runoff, thus protecting the waterway while also enriching the prairie plants, or forbs. The tallgrasses and forbs (“wildflowers”) of native tallgrass prairies include big bluestem (Andropogon gerardii), Indian grass (Sorghastrum nutans), switch grass (Panicum virgatum) and a dozen or more species. All of these once grew naturally in northwest Ohio and exist today in a few “remnant prairie” ecosystems. Thus tallgrass prairies can be commercially planted with success in Ohio.

From John’s research with colleagues and published supportive findings from Iowa State University, he developed methods of planting a robust mix of native Ohio prairie species. He has planted them in several sites, including the NASA Glenn Research Center’s large Plum Brook Station near Sandusky, Ohio. Iowa State University has proved the ability of the prairie plants to absorb the renegade nutrients. The critical step is to persuade those engaged in Ohio agriculture to plant 30–60’ strips of tallgrass prairie species along the downslope edges of row-crop fields, where runoff water percolates before draining downstream to Lake Erie.

Criticality? High. 

With these strips, Iowa research shows that up to 84% of the nitrogen runoff and 90% of the phosphorous can be captured by the plants, and the water running into the river is virtually clean. The levels of nitrogen and phosphorus exiting the field can no longer foster blooms of toxic green algae, such as those that crippled Toledo’s water supply in 2014.

Vulnerability beyond Lake Erie?

Non-point source pollution (i.e. sediment and nutrient runoff from ever-more-intense rainfall events onto rural row-crop fields, suburban fertilized lawns, and massive expanses of roadway and urban pavement) lies at the root of Lake Erie’s problem. This problem however extends beyond harmful algal blooms in streams, lakes, and Toledo’s drinking water source. It is the cause of huge hypoxic zones in the Great Lakes, the Gulf of Mexico (from the Mississippi River drainage), and North American eastern coastal waters.

Some good news?

Several Ohio farmland stakeholders are listening and learning about prairie grass strips at field edges. They are considering how to research and demonstrate upland prairie nutrient-retention strips so more farmers, in time, might use this algal nutrient-suppression practice. Expansive adoption of these strips will reduce phosphorous and nitrogen runoff from agricultural lands, helping obviate harmful algal blooms in Lake Erie.

Jones_130520_IA_8938.jpgTallgrass Prairie, University of Southern Iowa.

All communities need to reduce non-point source pollution. There are many ecological practices communities can practice, including:

  • decreasing suburban and urban pavement
  • increasing tallgrass and forb plantings
  • designing prairie and wetland drainage swales
  • conserving water use

If we all understand the sources of pollution and commit to take action, it will only be a matter of time before other watersheds in Ohio and across the country increase their water quality by using upland prairie nutrient-retention strips and thus also expand green spaces.

How can you be part of the solution?

First, become informed. Many US federal, state and community governments are measuring and attempting to act on non-point source pollution. Learn more about your state and community programs.

Second, take action by changing your and your family’s personal water use. Change your home and neighborhood water and rainwater practices. Here are some suggestions from The Nature Conservancy.

Lastly, connect back with No Water No Life. Let us know how you and your neighbors outreach to community, state, and federal government leaders is changing infrastructure and community water resource practices.

The strongest governments on earth cannot clean up pollution by themselves. They must rely on each ordinary person, like you and me, on our choices, and on our will.  –2015 Chai Jing, Chinese investigative reporter, and documentary film maker.
