Evaluation of Agricultural Best-Management Practices in the Conestoga River Headwaters, Pennsylvania: Description and Water Quality of the Little Conestoga Creek Headwaters Prior to the Implementation of Nutrient Management

摘要

The report describes and characterizes the water quality of the Small Watershed before implementation of nutrient management (pre-BMP). The basin represents one of the components of the Conestoga River Headwaters RCWP project. The report describes precipitation, land use, soils, streamflow, and surface-water and ground-water quality data collected during the pre-BMP phase. It includes information on the water quality of base flow and stormflow as well as the effects of geology and periodic discharges from agricultural point sources on water quality in the Small Watershed. The report provides estimates of the probability that the sampling scheme will detect changes in water quality in base flow. These probabilities are a function of the magnitude of the underlying change.
