Tearing Down The Elwha River Dam -

The two reservoirs must ultimately be drained of 48,600 acre-ft. of water--enough to flood Safeco Ballpark in Seattle, the home of the Mariners, to the height of a 130-story skyscraper. Then there is the reservoirs' sediment, 18 million cubic yards of the stuff, an amount so large that scientists have studied the debris flows from the explosion of Mount St. Helens to gauge how aquatic life will react to it washing downstream. Reservoir drawdowns will be carefully timed to manage turbidity.

By late 2011, both dams will be history, reservoirs drained and raw banks softened by sprouting trees. It will take three to five years for the river to flush out excess sediment, but the fish, Winter says, will likely reappear in a few months. It will be 30 years before the population is fully restored.

Biggest Dam Removal In U.S. History Underway

SustainableBusiness.com News

The largest dam removal project in U.S. History is undeway in Olympic National Park in Washington State.

Two dams on the Elwha river, constructed 100 years ago without fish ladders, are being taken out to restore roughly 70 miles of river and stream habitat for wild salmon.

Tom Banse of OPB News filed a radio report on the efforts, stating that salmon still come to the base of the lower dam after all these years and swim about aimlessly with no route to move farther inland.

Removal of the dams has been under consideration since 1986, when the Lower Elwha Klallam Indian tribe first challenged the relicensing of 210-foot tall Glines Canyon Dam and the 108-foot tall Elwha Dam.

Several other dams around the country are slated to be torn down next year as well. That includes Pacific Power's 125-foot tall Condit Dam on the White Salmon River near Portland
