DESCRIPTION

Updated: 11/5/2021

Removal of two hydroelectric dams on the Elwha River was initiated in 2011 as authorized by the Elwha River Ecosystem and Fisheries Act (PL102-495). Elwha Dam was completely removed in the spring of 2012 and Glines Canyon Dam is expected to be removed during 2014. Complementary to this large scale ecosystem restoration project, ongoing efforts are being made by LEKT to restore floodplain habitat conditions in the lower Elwha River below River Mile (RM) 3.5. These efforts include the removal of older flood control dikes, reforestation, control of exotic plants, barrier corrections and additions of large wood. Between 1999 and 2017, 52 engineered logjams (ELJ) have been constructed in the reach between RM 1.0-3.5. This is one of the largest scale projects of its kind anywhere in the world. ELJ's have proven effective at positively influencing physical habitat with documented benefits to salmonids. This proposal is focused on the construction of up to 50 ELJ's in the lower river RM 0-1.0 and the former Aldwell Reservoir RM 6.0-7.0, both areas that have been previously untreated.
