1933, Rock Island Dam was completed 44 miles south of the
Canadian border was completed in 1933 as detailed in this page about Native Fisheries.
The Native Americans immediately complained to Congress about how
the dams were going to destroy all of the fish. In response
to these claims that the dams would kill all of the
fish, fish-ladders were ordered by Congress and testing of the
downstream passage survivability was conducted.
Live-fish testing was conducted by
putting live fish into the turbines and catching them with nets across the
Observations of these fish found
survival rates to be greater than 95% so the dams were deemed "survivable" to
the downstream migrant fish. This was a satisfactory arrangement for everyone.
Dams were built, electricity was being generated and fish could pass the dams in
both directions with acceptable survival rates.
Everything went fine until the
1980's when the fish populations suddenly went into a serious decline.
This coincides with USACE Hydro Design Center deploying their first generation of
*Seawell electronic 3-D cams.
Placing the events about the turbine
control systems into this timeline of the impact of hydropower on fish
populations will provide a greater
understanding of this root cause of the fish mortality problem and the turbine
blade misalignment. Procurement favoritism in the
acquisition and deployment of the turbine blade controls systems all along the
Snake and Columbia Rivers, which started in the mid 1980's after USACE Hydro
Design Center reverse-engineered Woodward's electronic 3-D cam.
*Seawell was the name of the
company that built and deployed the first generation of USACE's 3-D cam designs.
Note that in 1980 USACE acquired 18 perfectly functional Woodward Governor
electronic 3-D cams for Bonneville Dam, then - as if that acquisition had
never happened USACE claimed to have "invented" a digital electronic 3-D cam
years later in 1990. This new "invention" of USACE's personnel was
subsequently deployed into every hydropower dam on the Snake and Columbia
Rivers. It is our contention that this one action is a root-cause of the
 FALL CHINOOK COUNT CLIMBING FAST Cool weather and a hard rain likely
played a large role in this year's early return of fall Chinook to the Columbia
River. Harvest managers had hoped to keep the popular Buoy 10 fishery in the
lower river open through the Labor Day weekend, but anglers had caught their
6,500-fish quota by Aug.
SAYS NO TO BIOP SCIENCE REVIEW Federal District Court Judge James Redden
ruled Aug. 21 that the new BiOp will not get any independent scientific scrutiny
before he decides whether to throw it out. Plaintiff environmental and fishing
groups are mounting a challenge to the new salmon plan and have asked for such a
review. But attorneys for the defendants, especially Coby Howell from the
Department of Justice, evidently swayed the
NIŅA LINGERS, BUT FOR HOW LONG? La Niņa is lingering, but that part of the
world where El Niņos are born is warming once again. In the equatorial Pacific,
waters have warmed to above-average temperatures in some places, from several
degrees below average last winter. The waters off Washington and Oregon have
remained 2 degrees F below average. How long that will last is anybody's guess.
The Sept. 2 update from the National Oceanic and Atmospheric Administration's
Climate Prediction Center says El Niņo/Southern Oscillation-neutral conditions
are expected to continue through the
COUNCIL FINISHES DRAFT 2008 F&W PROGRAM The Northwest Power and
Conservation Council voted 6-2 on Aug. 28 to release its latest draft of the
region's fish and wildlife plan for public comment. It's the latest step in an
amendment process that began last October. Oregon members voted against
releasing the document. A final version will be released after a 60-day public
DEAL REACHED OVER FLOWS FOR KOOTENAI STURGEON All parties in litigation over
the USFWS' 2006 sturgeon BiOp have reached an agreement that calls for extending
interim operations at Libby Dam to help the ESA-listed sturgeon spawn in the
Kootenai River below the dam. If these attempts at mimicking spring flows and
reducing temperatures don't work, the Corps of Engineers will then boost
spillway flows to see if that helps the sturgeon to
