The Willamette Valley Project (WVP) is a system of revetments, fish hatcheries, and 13 dams in the Willamette Basin of northwestern Oregon that is operated by the U.S. Army Corps of Engineers to provide flood risk management, irrigation, power generation, water quality improvement, and recreational opportunities, among other authorized purposes. By reducing available habitat and altering the natural hydrologic and thermal regimes in the Willamette Basin, the WVP has negatively influenced native populations of anadromous fish, including spring-run Chinook salmon (Oncorhynchus tshawytscha) and winter-run steelhead (O. mykiss), which were designated as threatened under the Endangered Species Act of 1973 (Public Law...
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...

The U.S. Army Corps of Engineers (USACE) and the Nature Conservancy developed the Sustainable Rivers Program (SRP) as a collaborative environmental flows program to identify, refine, and implement environmental strategies at select USACE dams. The SRP was introduced to the Willamette Basin, Oregon, in 2007 through a series of environmental flow workshops, which led to stakeholder generated environmental flow recommendations in the North Santiam, South Santiam, Santiam (Bach and others, 2013), McKenzie, South Fork McKenzie (Risley and others, 2010), and Middle Fork Willamette Rivers (Gregory and others, 2007, https://www.hec.usace.army.mil/sustainablerivers/). This data release is a compilation of the stakeholder-defined...

This data release contains estimated stream temperature metrics at three locations in the Willamette River Basin, northwestern Oregon for various periods between 1954 and 2018. These locations were the Willamette River at Albany, the Willamette River at Harrisburg, and the Willamette River at Keizer. A regression program (written in the R programming language) was used to relate the values for two stream temperature metrics (the seven-day average of the daily mean and the seven-day average of the daily maximum) to the seven-day average of the daily mean or the seven-day average of the daily maximum air temperature, and to the mean daily streamflow for five seasonal time periods at each of the locations. The regression...
