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.
