A 12-year (1968--1980) hydrologic database has been developed for three sets of watersheds on the frail land resource area located near Ekalaka in southeast Montana. These records contain daily maximum and minimum air temperature, precipitation, runoff, soil water measured monthly and more often during the growing season, and breakpoint precipitation and runoff for summer runoff events. These data can be accessed from the U.S. Department of Agriculture, Agricultural Research Service, Northwest Watershed Research Center, Boise, Idaho database through the anonymous ftp site ftp.nwrc.ars.usda.gov.
