Contents Notes
"This study was conducted to evaluate the effects of cattle grazing on runoff volumes and rates, erosion and sedimentation, and chemical and bacteria concentrations and quantities in the surface runoff discharged from agricultural watersheds in the principle grazing areas of the Pacific Northwest. The purpose of this study was to document these water quantity and quality variables over a period of 3 years from a small watershed managed in a typical fashion for this region under sustained economic production without obvious resource abuse. The effects of management alternatives were not evaluated, but the impact of cattle presence was defined by excluding grazing on a smaller, but otherwise similar, grazed watershed. Although a wide variety of water quality parameters were measured on the analyzed samples (approximately 23 types of determinations), special emphasis was given to the bacterial analyses because the animal presence was expected to have more effect on these than on any other parameter."
