Laboratory and field investigations characterized suspended sediments from watersheds of varied hydrologic, soil and land use characteristics. Agricultural activities in the dryland wheat region of eastern Washington contributed large amounts of sediments and dissolved nitrogen during heavy runoff periods, whereas urban activities provided substantial nitrogen and phosphorus during the remaining months. Chemical 'fingerprints' suggested that most suspended solids originated from actively-eroding agricultural fields, rather than from channel erosion. In irrigated portions of the Yakima Valley, furrow irrigation management had a significant effect on sediment and nutrient contents or irrigation return flows, with sediment concentrations substantially higher than permitted by proposed water quality standards.
