Judge Refuses To Halt Lethal Removal Of Cormorants
Oregon federal judge Michael Simon ruled May 8 against bird lovers--Audubon Society of Portland et al. v. U.S. Army Corps of Engineers et al.--trying to stop a Corps of Engineers' plan that calls for shooting up to 3,500 double-crested cormorants in the lower Columbia River each year for the next four years. The drastic strategy is part of a management plan to reduce avian predation on ESA-listed juvenile salmonids that is one of the 73 actions called for in the 2014 hydro BiOp. ...more
Scientists Update Estimates Of Avian Predation
Researchers studying bird predation on young salmonids in the Columbia River Basin told the Northwest Power and Conservation Council's Fish and Wildlife Committee that the birds are eating a lot more fish than they previously estimated. ...more
No Quick Fix For Reintro Funding
BPA officials told the Northwest Power and Conservation Council's Fish and Wildlife Committee on May 5 just how difficult it would be to find $3 million of cost savings to pay for any of the Council's new priorities before FY 2017.

Their preseason prediction was 232,000, which had been updated to 220,000 on April 29, but was revised again after a healthy show of fish at Bonneville Dam over the next few days. ...more
A Fresh Look At Fish Supplementation
A new paper by fishery scientists using statistical techniques borrowed from advanced financial analyses indicates efforts to use hatchery fish to boost natural populations may have had slight benefits for some ESA-listed spring/summer Chinook stocks in Idaho. ...more
Dry Year Won't Keep BPA From Meeting Loads
Despite a "dismal snowpack" and below-normal stream flows in many rivers, the Northwest should produce more than enough hydroelectricity to satisfy regional demand, according to a Northwest Power and Conservation Council briefing on May 6. ...more
Water Supply Worries Keep Managers On Their Toes
There's only so much water that can be used for augmenting flows to aid migrating juveniles this spring, given the low-flow year that seems to be getting lower each week, fish managers heard April 29 at the weekly Technical Management Team (TMT) meeting in Portland. ...more
