How Wolves Change Rivers

February 26, 2014

This video, How Wolves Change Rivers, explains the “balance-of-nature“ phenomena scientists call a “trophic cascade.” NWNL also documented this on its Greater Yellowstone Ecosystem Expedition in 2008. When wolves were reintroduced into Yellowstone National Park, it had a very beneficial impact on the ecosystem and on water flows. Although the video mislabels the elk as “deer”, its message is relevant.

The influence of just a small group of wolves on river systems is as magical as the cry of the wolf itself. For a sense of being on the Yellowstone River in the Missouri-Mississippi headwaters, do look at our Yellowstone Species photo gallery.

WANTED: More Potamologists*

February 25, 2014

*Potamologists – Those who study the science of our river channels and impacts of river infrastructure (dams, levees, bridges, etc.)

(civil engineering) The systematic study of the factors affecting river channels to provide the basis for predictions of the effects of proposed engineering works on channel characteristics.

What's Your Water Footprint?

Did you know that the American lifestyle takes up 2,000 gallons of H2O a day – That’s twice the global average!

Take this short, interactive quiz at National Geographic to find out if your water usage is average or extreme.

Ethiopia: Dams threaten Indigenous communities, Omo Valley, Lake Turkana

February 21, 2014

A Cascade of Development on the Omo River by International Rivers, with photos by Alison M. Jones, 2014 (11:19).

This film outlines how Ethiopia’s new Gibe Dams will cause a 70% water-level reduction over the next 3 years – and thus drastically impact Ethiopia’s Omo River, its Lake Turkana terminus in Kenya, and ½ million residents in this Rift Valley’s Cradle of Humankind. These hydro-dams – and the new commercial agricultural plantations they will irrigate – threaten the livelihoods of local indigenous tribes and their ecosystems. The Gibe Dams will also imperil the Omo-Turkana Basin’s migrating birds, fish and crocodile populations, and the scant amount of wildlife left.

The film pleads that water flows be managed so as to maintain the sustainability of the Omo River, Lake Turkana, and today’s indigenous communities who represent 6000 years of self-sustaining flood-recession farmers and fishermen. For more information on the Omo River :
 Download the factsheet on Gibe III Dam by International Rivers.

ADDITIONAL THOUGHTS FROM NWNL:  For many millennia, the Omo’s annual 60 foot floods from the highlands’ monsoonal rains have supplied nutrient-rich silt and irrigation for the crops of the Mursi, Suri, Karo, Hamar, Nyangatom, Dassanech and other
unique indigenous cultures. In a 2008 NWNL interview…. Read the full story here.

Alarm Bells are Ringing – Let’s Wake Up

February 14, 2014

Ten days ago 82,000 tons of coal ash slurry began to spill into North Carolina’s Dan River due to a 48” broken pipe owned by Duke Energy. This is what a similar 2008 coal ash spill in Kingston TN looks like today – 6 years into a still-ongoing cleanup!

This past October, NWNL documented the cleanup site of the 2008 dike collapse at a TVA (Tennessee Valley Authority) coal-ash impoundment. The storage was for a Kingston TN Fossil Plant that provides electricity for Oak Ridge National Labs. One billion gallons of slushy coal ash spilled into the Emory River (a tributary to the Tennessee River), and onto 300 acres, covering farms, homes and waterways with up to 6 feet of sludge. Tennessee fined TVA $11.5 million for violating state clean water and solid waste disposal laws.

Such disasters typically stem from lack of comprehensive Federal Regulations on handling and disposal of coal ash, non-compliance of existing regulations, and little or no compliance supervision. To learn more about coal ash spills, and follow the Dan River cleanup and legal actions underway in North Carolina, go to http://www.coalashchronicles.com.

Cleaning up TVA's coal fly ash spill

Cleaning up TVA’s coal fly ash spill

For 6 years, the TVA clean up has been repairing the soil, a washed out road, a ruptured major gas line, an obstructed railroad line, a water main and power lines. TVA’s cleanup extends 6 miles upstream and 1.5 miles downstream to “bring the area back to the way it was before and even better.” TVA told NWNL in October that the covered storage of this spill is earthquake-proof down to bedrock (a unique feature for cleanups thus far) and that the river’s fish and fresh-water mussels that were affected have been recolonized.

A similar cleanup is now needed for NC’s Dan River spill.  In an effort to prevent further spills, TVA is spending $1.5 to $2 billion to convert all other TVA coal plants to dry ash storage in a ten-year plan. North Carolina’s Duke Energy now states it has been planning ash basin closures.

This month’s North Carolina spill comes on the heels of West Virginia’s chemical spill into its Elk River, which left 300,000 people with non-potable water for days. The continuance of such spills damaging our rivers, ecosystems and fresh water supplies is one more wake-up call that we need to become more responsible with our waste. Our polluting waste includes coal slurry – and nuclear waste, desalinization’s briny residue, toxic chemicals and pharmaceuticals. These pollutants dirty our rivers, kill our fish and damage our crops.

As conservation author Wallace Stegner wrote,
Something will have gone out of us as a people if we let the remaining wilderness be destroyed; if we permit the last virgin forests to be turned into comic books and plastic cigarette cases; if we drive the few remaining members of the wild species into zoos or to extinction; if we pollute the last clear air and dirty the last clean streams and push our paved roads through the last of the silence . . .” 


NWNL Interview with Ray Gardner featured in Terralingua Langscape

Screen Shot 2014-02-12 at 4.32.58 PM

NWNL’s Alison M. Jones interviewed Ray Gardner, Chairman of the five tribes of the Chinook Nation, in June 2007. The interview describes the historic ties the Chinook people have had with the Columbia River, their practices to keep the river healthy, and effects of dams and other infrastructure placed along our rivers. You can read the interview here.

Terralingua featured the interview in their Winter 2013 issue of Langscape, pages 54–57.

“GLOOP” threatening global watersheds

February 11, 2014

GLOOP by Gaby Bastyra, 2010 (3:48).

A documentary short told as a nursery-school chant by a young girl tracing the discovery and impacts of plastic on our oceans, rivers and environment in general. Putting this message in the mouth of today’s youngest generation adds a gutsy impact to the now-familiar story of the forever-here debris of non-biodegradable plastics that seem to be in every corner our life.

“…Plastic doesn’t go away, all plastic things are here to stay…”

Respect for the wild river

“For many of us, water simply flows from a faucet, and we think little about it beyond this point of contact. We have lost a sense of respect for the wild river, for the complex workings of a wetland, for the intricate web of life that water supports.”

Put your swamp boots on! It’s World Wetlands Day!

February 2, 2014

World Wetlands Day is celebrated internationally on February 2nd. It marks the date of the Ramsar Convention of 1971.

Fun Fact: This year is the 40th anniversary of Australia’s Cobourg Peninsula being listed as the world’s first Wetland of International Importance under the Ramsar Convention.
