Baseflow Time Series for Selected USGS Gages

Daily estimates of baseflow derived from a non-linear, baseflow separation model. The file "baseflow_puget.csv" has daily baseflow estimates for 134 sites in HUC 1711 (Puget Sound basin) for the period from water year 1981 to 2015 used for estimating groundwater recharge in lowland areas. The file "baseflow_rsqa.csv" has daily baseflow estimates for 462 sites that were sampled as part of the US Geological Survey Regional Stream Qualtiy Assessment (RSQA). Values are only provided for days when water samples were collected. Missing values indicate gaps in the streamflow record.
