Rising water temperatures and poor passage are causing Oregon and Washington fishery managers to shut down fishing at the mouth of the Deschutes River in Oregon and the mouth of the Yakima River in Washington.
Representatives from the Idaho Department of Fish and Game, the Idaho Department of Environmental Quality, and Idaho Power have concluded that the cause of a recent fish kill in the Snake River immediately below American Falls Dam was a lack of sufficient oxygen in the water.
The number of summer chinook salmon expected to enter the Columbia River took another nose dive last week when biologists that estimate those numbers downgraded the run another 15 percent.

With high river flows, low visibility and an apparent lack of angling success, Washington and Oregon extended spring chinook angling downstream of Bonneville Dam and increased the bag limit for hatchery salmon to two per day.
A suppression program in the largest lake in Idaho to significantly reduce the number of lake trout has been successful at recovering the lake’s kokanee population, but biologists are now worrying about another invasive predator – walleye.

With low returns of chinook and coho salmon expected back to numerous rivers in Washington, state and tribal co-managers Tuesday agreed on a fishing season that “meets conservation goals for wild fish while providing fishing opportunities on healthy salmon runs,” said the Washington Department of Fish and Wildlife.
Idaho Fish and Game fisheries managers are considering changes in how lake trout and kokanee salmon are managed in Payette Lake, which is part of the Columbia Basin’s interior waters.
Abundance of Columbia River smelt is so low this year that the Washington Department of Fish and Wildlife has decided not to open the Cowlitz River to recreational smelt dip-net fishing.
Spring chinook salmon fishing begins for recreational anglers next week in the lower Columbia River and two weeks later upstream of Bonneville Dam.
Anglers fishing the Snake River and some of its tributaries in Oregon, Washington and Idaho can keep two to three steelhead per day until further notice.

Landing nets in catch and release fisheries are recommended to shorten fight time, reduce handling time and to protect fish from harm when handling the fish.
Idaho opened three rivers – the Snake, Clearwater and Salmon rivers – last Sunday, October 15, allowing anglers to keep up to two hatchery steelhead per day.
The two-state Columbia River Compact this week opened white sturgeon angling on two days later this month for the area below Bonneville Dam and upstream of the Wauna Power lines at river mile 40.
After considering an Idaho Department of Fish and Game proposal to reopen steelhead fishing for hatchery fish smaller than 28 inches and with a reduced bag limit, the Idaho Fish and Game Commission decided instead to ask for public input on the proposal.
The Idaho Fish and Game commissioners on Oct. 2 set a fishing season for coho salmon, which will run Oct. 17 through Nov. 16, or until further notice.

Washington State salmon managers are encouraging anglers to fish for thousands of Atlantic salmon that escaped recently from a salmon farm near the San Juan Islands.
Adrenaline and noradrenaline, the "fight or flight" hormones, peak first, followed more gradually by cortisol. A new study http://jeb.biologists.org/content/220/14/2529 finds that largemouth bass whose cortisol levels rise most after a brief bout of stress are inherently harder to catch by angling.
