Here I provide water year discharge (Q) and precipitation (P) in units of mm as well as the water year runoff ratio (Q/P) for all reference USGS watersheds as defined by the GAGES-II project (Falcone, 2011) for water years 1981 to 2016. Precipitation values were extracted from PRISM monthly totals for the "Recent years" 4 km gridded dataset, and discharge values come from summations of USGS daily mean streamflow values. The dataset contains Q, P, and Q/P data by watershed for 1,594 reference USGS watersheds.
