USGS Surface Water Information

USGS Hydro-Climatic Data Network (HCDN-2009). This data set is very small, consisting of just an EXCEL file with information on USGS stream gage stations that are unaffected by human interventions and therefore appropriate for use to evaluate historical hydrological observations that are attributable only to climatic variations. Updated in 2009. The actual streamflow data can be downloaded from https://waterdata.usgs.gov/nwis/sw.
