Gebert, W.A., Graczyk, D.J., and Krug, W.R., 1987, Average annual runoff in the United States, 1951-80: U.S. Geological Survey data release, https://doi.org/10.5066/P9EMWILT.

This coverage is intended as a thematic data layer representing average annual runoff, in inches per year, for the conterminous United States. Appropriate maps of the data can show the geographical distribution of runoff in tributary streams for the years 1951-80 and can describe the magnitudes and variations of runoff nationwide. The data was prepared to reflect the runoff of tributary streams rather than in major rivers in order to represent more accurately the local or small scale variation in runoff with precipitation and other geographical characteristics. Information contained in the runoff coverage has been used for several publications. The first is the 1985 National Water Summary (U.S. Geological Survey, 1986), which contained state by state maps (scales 1:3,000,000 to 1:7,500,000) as well as a national map of runoff. The second publication is HA-710 (Gebert and others, 1987).
