PORTLAND, Ore., July 26 /PRNewswire/ -- Voith Hydro's first-of-its-kind patented fish friendly hydropower turbines are giving new life to the Bonneville Dam, after more than 70 years of providing clean, renewable energy to the Pacific Northwest. The Bonneville First Powerhouse, which has been harnessing hydropower from the Columbia River since the late 1930s, underwent a $140 million upgrade to its turbines. The project, which started in 1993, was just celebrated in a public ceremony last...

The killing of 25 California sea lions over the past two years has had no affect on the growing population of salmon at the base of Bonneville Dam in the Columbia River. The U.S. Army Corps of Engineers estimates sea lions ate 4,960 salmon and steelhead during the spring of 2009. That compares to an adjusted estimate of 4,927, or 2.9 percent of the run, in 2008. Sharon Young of the Humane Society of the United States said the numbers show that trying to restore salmon by killing predators...

By ALLEN THOMAS Fall chinook salmon retention in the lower Columbia River will not close early, instead remaining open through Tuesday. Washington and Oregon officials made the decision on Thursday to leave fall chinook angling between Tongue Point and Bonneville Dam open through the scheduled season, which concludes at the end of Tuesday. Chinook retention at Buoy 10 in the Columbia River estuary closed a week earlier than scheduled, and rumors on the river had an early closure looming...

By ERIK ROBINSON Sea lions sit in two traps on the Columbia River near Bonneville Dam on April 24, shortly before the doors closed, trapping them for removal. The deaths of six sea lions at Bonne-ville Dam remains a whodunit. On May 4, six carcasses were discovered in a pair of side-by- side floating traps below the dam. State employees had been using the traps to capture and relocate sea lions feasting on endangered salmon at a man-made bottleneck. Federal and state authorities...

By ALLEN THOMAS Odds and ends from the Columbia River fisheries realm.... Big changes are coming to the operation of salmon and steelhead hatcheries on lower Columbia River tributaries. It's called the "Conservation and Sustainable Fisheries Plan,'' and the basic goal is to help wild salmon and steelhead populations rebuild by reducing the competition they face from hatchery-origin fish. "The biggest problem is that too many hatchery fish are overwhelming the wild fish on the spawning...

By Scott Learn, The Oregonian, Portland, Ore. Jul. 24--One of the great fish surprises in years has landed in the Northwest: Sockeye salmon, an ocean-going species that starts and ends its life hundreds of river miles inland, have swum their way up the Columbia River this summer in numbers unseen in five decades. No one knows exactly why. Some say it's because federal courts ordered the release of extra water over dams in 2006 and 2007 to make passage easier when the fish were young...

By ERIK ROBINSON Anglers line the north bank of the Columbia River below Bonneville Dam to fish for shad in June. A new scientific report recommends policymakers pay more attention to the harm caused to native plants and animals by invaders such as shad, an East Coast native that now forms the single largest mass of fish in the lower Columbia River. Shad, native to the East Coast, were brought west in the 1870s. Most Columbia River anglers have no reason to know the name Seth Green....

By ALLEN THOMAS Having exceeded harvest guidelines, sturgeon angling in the Bonneville pool of the Columbia River Gorge will shift to catch-and- release beginning Saturday. Washington and Oregon fishery officials made the decision Tuesday to end retention of sturgeon between Bonneville and The Dalles dams effective 12:01 a.m. Saturday. The catch through last Saturday was 786 sturgeon on a guideline of 700 for Bonneville pool in 2008, said Olaf Langness, a biologist for the Washington...

By ALLEN THOMAS Conflict swirls constantly around Columbia River salmon management. It's as much a part of the river as the tides and eddies of the stream itself. One group is chafed about the fisheries of another incessantly. So who's upset with who right now: Both the Columbia treaty tribes and the non-Indian lower river gillnetters are irked at the Washington and Oregon fishery agencies about the summer chinook season. Sport fishermen between Tongue Point near Astoria and...
