The Department of Ecology contracted with Portland State University (PSU) to develop a CE-QUAL-W2 water quality computer model for the Spokane River and Lake Spokane from recent and past studies. Ecology used this model to predict water quality changes in response to various scenarios and applied the information in the Spokane River and Lake Spokane DO TMDL.
Current and past modeling reports and input files are provided at the links below. Any additional modeling undertaken should make sure they are using the most current model input files.
