Climate Change Streamflow Scenario Tool
Climate Change Streamflow Scenarios
ARCHIVE: This tool was replaced in spring 2009 with an expanded set of streamflow locations (271 sites) and modeled variables (in addition to streamflow). This page is currently not being supported.
Columbia River Basin
Forty-year time series of monthly average streamflows associated with the climate changes projected for the 2020s and the 2040s (along with observed naturalized flows) are available at the locations shown on the map below.
To view and/or download historic and climate change data for a specific location, click on the name of the location on the list below the map.

Modified Flows based on A.G. Crook Co. Data Set
A set of modified flow scenarios at 71 flow locations in the Columbia River basin have been produced for the GENESYS simulation model. These flows are consistent with the A.G. Crook Co. 1990 level modified flow data set that is widely used for reservoir model simulation. Click here for additional information and data.
Additional data for the Snake is available from the SnakeSim model. Click here for additional information and data.
