Washington State Department of Ecology 20000330 Baseflow Stations 1 vector digital data Baseflow Stations Olympia, Washington Washington State Department of Ecology baseflow Automated hydrograph separation techniques were used to evaluate the groundwater contribution to total streamflow (baseflow) at active and inactive stream guaging stations throughout Washington State. Discharge records for 582 guaging stations, with at least three complete water years of daily mean streamflow data, were downloaded from the U.S. Geological Survey (USGS) National Water Information System. Station characteristics were compiled for each gage, including period of streamflow record, type and degree of regulation affecting the gage, watershed drainage area, USGS station number, station name, and gage location. Summary statistics were calculated for annual mean streamflow and annual 7-day low flow for all 582 stations. Monthly, and in some cases annual, statistics for baseflow were then estimated using a USGS hydrograph separation software program called HYSEP (Sloto and Crouse, 1996) for those stations judged to be free of significant snowmelt or regulation effects. To improve our understanding of the baseflow characteristics of Washington rivers and streams and the role groundwater discharge plays in maintaining streamflow. The methods used to define the baseflow and streamflow statistics are described in the following report: Estimated Baseflow Characteristics of Selected Washington Rivers and Streams, Water Supply Bulletin No. 60, (Publication No. 99-327) by Sinclair, K. A., and Pitz, C. F. 1999. The report is available at http://www.ecy.wa.gov/biblio/99327.html.
