Evaluating the Effects of Watershed-Scale Agricultural Best Management Practices on Water Quality

800 532 Stroud Water Research Center

In early 2020, a number of agricultural best management practices will be implemented on Amish farms in Lancaster County, Pa. The farms are nested in a small watershed drained by a heavily impaired headwater stream. As part of the restoration, stream bank fencing and forested buffer plantings will protect the stream along with barnyard improvements and field practices. We will monitor stream nutrient and sediment concentrations and loads before, during, and after the implementation of the BMPs. This effort is unique for two main reasons: first, the farmland extends over the watershed area almost entirely (a scenario that is hard to find in the landscape) and provides an opportunity to more accurately capture the effects of the restoration; and second, the monitoring will start prior to the implementation, which is often hard to achieve.
