| Abstract | The quantity and quality of runoff from six feedlots in eastern South Dakota has been measured over a 3-year period. Annual precipitation at the feedlots ranged from 19 to 25 inches which was about normal for the area. Snowmelt accounted for 27% of the mean runoff of 7.2 inches for the six lots. After snowmelt runoff, rainfall caused only about 10 runoff events per year and about 50% of the runoff events were less than 0.25 inches. Average annual losses of waste constituents in the runoff in lbs/acre/yr. were total solids - 10,332, BOD-1816, COD-7496, total phosphate - 351, and Kjeldahl nitrogen - 533, although there was wide variation between lots.
