Washington StreamStats

StreamStats for Washington was developed in cooperation with the Northwest Indian Fisheries Commission, the Point No Point Treaty Council, the Washington State Department of Transportation, and the Washington State Department of Ecology.

Two reports document the regression equations available in StreamStats for Washington, the errors associated with the estimates, and the methods used to develop the equations and to measure the basin characteristics used in the equations. Users should familiarize themselves with these reports before using StreamStats to obtain estimates of streamflow statistics for ungaged sites.
