The objective of this research was to determine the role of stream-bed sediments with respect to increased phosphorus concentrations during high flow periods. Both point and nonpoint sources were considered. Core samples of sediments were evaluated for total and organic phosphorus content. Total phosphorus, total filtrable phosphorus, and filtrable orthophosphate were determined on water samples. Stream-bed sediments play a major role with respect to increased phosphorus concentrations of streams during high flow periods.
