Water samples were collected once each week during the 1967 water year from four small watersheds representing three different soil associations in a rural area. Three stations on two streams were selected to coincide with U.S.G.S. gaging stations. These streams received municipal and industrial wastes as well as rural runoff. Flow data were obtained during the period of study so watershed runoff could be determined. Loading was determined from nutrient concentrations and flow data. The following determinations were made: air temperature, water temperature, conductivity, field pH, laboratory pH, dissolved oxygen, chlorides, nitrate nitrogen, total Kjeldahl nitrogen, soluble phosphorus, and total phosphorus. From July 21 to September 29, 1967, additional samples were collected every two weeks and analyzed for pesticides. Average concentrations of nitrate nitrogen and soluble phosphorus for the year were higher than those required to stimulate nuisance algal blooms in reservoirs. Pesticide concentration in runoff water was negligible. Statistical tables, charts, and a bibliography are included in the report.
