Environmental flows are defined as "streamflow needed to sustain ecosystems while continuing to meet human needs."
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.
