Well-placed woody debris in streams results in a two- to three-fold increase of juvenile salmon, according to a recently completed review.

Water supply forecasts at major dams in the Columbia River basin dropped again during March, with the forecast at The Dalles Dam dropping from 83 percent of normal in February to 80 percent of normal in March, according to the April 3 water supply forecast by NOAA’s Northwest River Forecast Center.

A new report released by the U.S. Fish and Wildlife Service reveals wetlands – 95 percent of which are freshwater — covered less than 6 percent of the lower 48 states as of 2019 – which is half the area they covered since the 1780s. The report also identifies that loss rates have increased by 50 percent since 2009 and that without additional conservation actions taken to protect these ecosystems, wetland loss will likely continue, reducing ecosystem benefits for people and habitat for fish, wildlife and plants.

With lower-than-normal temperatures and near normal precipitation in February across the Columbia River basin, the March water supply forecast is showing some improvement over the last two months.

The U.S. Environmental Protection Agency announced this week it is proposing to add the Upper Columbia River Site in northeast Washington to the National Priorities List, the list of hazardous waste sites in the United States eligible for cleanup financed under the federal Superfund Program.
