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...

To meet their permit requirements under the water-temperature Total Maximum Daily Load for the Willamette River, Oregon Association of Clean Water Agencies members need to understand the potential thermal effects of various heat-mitigation alternatives for their treated wastewater discharges to the Willamette River, such as the installation of cooling towers that would decrease the temperature of their effluent. CE-QUAL-W2, a two-dimensional, hydrodynamic water quality model, has been used to investigate temperature and heat patterns in the Willamette River, the downstream effects of dam operations, and other anthropogenic effects on stream temperature such as effluent discharge from waste-water treatment plants....

Streamflow and stream temperature in the Donner und Blitzen River Basin for water years 1980 through 2021 were simulated using the Precipitation-Runoff Modeling System (PRMS) with the "stream_temp" module. The model domain was discretized into 175 stream segments and calibrated to observed streamflow and stream temperature at points distributed throughout the basin. Model input files, including a PRMS control file, parameter file, and meteorological forcing files, are included in the Blitzen_PRMS_input.zip file. Select output variables for each hydrologic response unit (HRU), each stream segment, and PRMS basin summary outputs are included in the Blitzen_PRMS_output.zip file. Shapefiles of the model domain, model...

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...

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...
