| Abstract: | An investigation of nonpoint-source runoff from small watersheds in the Twin Cities metropolitan area was conducted to define relationships between land use, watershed characteristics, and the quantity, quality, and timing of runoff. Six rural and four urban watersheds ranging in size from 1.22 to 82.9 square miles were studied. Discharge and water-quality data were collected at 19 sites during 1980. Recording instruments and automatic samplers provided continuous discharge records at 17 sites, continuous rainfall records and automatic collection of samples at 12 sites, and wetfall/dryfall precipitation samples at six sites. Sampling was intensified during periods of increased runoff resulting from snowmelt and rainstorms. Primary emphasis was placed on analysis of samples for suspended solids, nutrients, and chemical oxygen demand. Samples were also analyzed for chloride, metals, bacteria, and pesticides. The data are documented in tables containing basin characteristics and land use, daily and unit values for discharge and rainfall, rainfall characteristics, water-quality data for runoff and precipitation, results of laboratory settling test, results of quality assurance tests, daily loads, and storm loads.
