Yakima River Water-Quality Studies
From 1986 to 2009, the USGS studied various aspects of watershed health in the Yakima River Basin. The results from these studies have been published and are available online.
Marmot Dam Removal
Marmot Dam on the Sandy River was removed in 2007 as part of decommissioning of Portland General Electric’s Bull Run Hydroelectric Project. Removal of the 15-meter-tall dam would allow the Sandy River to flow freely for the first time in nearly 100 years and make upstream habitat more accessible to anadromous fish.
