FISHING — Warming water temperatures in the Snake and Columbia rivers is catching the attention of fish scientists, especially those who support the removal of Snake River dams for the benefit of wild salmon and steelhead.
Following is the third memo in a series calling attention to the warming waters of the Columbia and Snake Rivers, and the impacts of those high water temperatures on migrating salmon and steelhead provided by Joseph Bogaard, deputy director, Save Our Wild Salmon Coalition, 206-286-4455 x103; firstname.lastname@example.org
Summer 2013 - Hot Water Alert No. 3
Columbia and Snake River temperatures over 70 degrees for third straight week
Memo to Northwest writers, reporters, editorialists, and columnists – August 7, 2013
For the week July 29 through August 4, water temperatures were 70 degrees or higher 45 times at Columbia and Snake River federal dams passable to salmon – up from 35 readings the previous week. At three dams – The Dalles and John Day on the Columbia, and Ice Harbor on the Snake – temperatures were above 70 degrees all seven days both above and below the dams. At Ice Harbor Dam, temperatures have now been above 70 degrees for 17 consecutive days; at The Dalles and John Day, for 11 consecutive days.

The Idaho Statesman reported August 3 that hundreds of endangered sockeye and chinook salmon were trapped in July by warm water at the base of the Lower Granite Dam fish ladder on the lower Snake. Turbine adjustments and auxiliary pumps finally got the fish moving up the ladder, but the situation could be a harbinger for days and years ahead.
FISHING — Anglers have until Monday to comment on proposals geared to helping them get the most out of a very limited spring chinook salmon fishing season being planned for the Snake River in late April and May.
“The 2013 run forecast is low, and following the restrictions of federal Endangered Species Act, the harvest allocation available for the Snake River is just 360 adipose-fin-clipped hatchery adults, at least until the in-season run update is available the first week of May,” says John Whalen, Washington Department of Fish and Wildlife regional fisheries manager.
The agency is asking anglers to choose one of three options and let biologists know by email to help them make a decision that will please the most anglers.

ENDANGERED SPECIES — Another point of view…
The Seattle Times' recent article on the federal government's work to save sockeye salmon estimated that the per-fish price tag of raising wild fish in hatcheries was $9,000, a spendy proposition that still has not pulled the species back from the edge of extinction, and a better method would be to remove the dams that block the wild fish's age-old migration from the West Coast to Redfish Lake in Central Idaho, according to an Idaho Statesman editorial.

RIVERS — The House Natural Resources Committee held a hearing in Pasco toda on “save our dams” legislation introduced by Congressman Doc Hastings.
The Tri-City Herald reports the legislation would prohibit federal money from being used to remove hydropower dams without specific authorization by Congress.
The bill also would:
Shouldn't the bill also assure the public knows the value of fish and wildlife lost to power production, and the associated health issues, and the cost to subsidize the barging industry and the federal cost to replace the dams and deal with the silt issues that will come to a head in the next few decades?
There's a cost to everything. To peg fish and wildlife as the villain is disingenuous.
RIVERS — In an interview for a television broadcast, U.S. District Judge James A. Redden, who presided over the Northwest's biggest salmon lawsuit for nearly a decade, said the Snake River's four hydropower dams should be breached to help wild salmon.
Redden made the comments to Idaho Public Television.
OUTDOOR TRAVEL — While dams operated by the Corps of Engineers generally are off-limits to vehicle crossings since the 9/11 attacks, Lower Granite Dam over the Snake River is scheduled to be opened for vehicle traffic Monday as a special Columbus Day treat.
