CE-QUAL-W2 models for the Willamette River and major tributaries downstream of U.S. Army Corps of Engineers dams: 2011, 2015, and 2016

May 12, 2022

In the Willamette River Basin in northwestern Oregon, stream temperature has been altered by 13 dams operated by the U.S. Army Corps of Engineers (USACE), negatively influencing threatened populations of native salmonids. CE-QUAL-W2, a two-dimensional, hydrodynamic water quality model, has been used to investigate temperature and heat patterns in the Willamette River and the downstream effects of dam operations and other anthropogenic effects on heat and stream temperature. This data release includes the input and output files for six CE-QUAL-W2 models that include Fall Creek downstream of Fall Creek Dam, the Row River downstream of Dorena Dam, the Coast Fork Willamette River downstream of Cottage Grove Dam, the Middle Fork Willamette [...]
