Study design and preliminary data analysis for a streambank fencing project in the Mill Creek Basin, Pennsylvania

April 1, 1997

The Pequea Creek and Mill Creek Basins within Lancaster and Chester Counties in Pennsylvania have been identified as areas needing control of nonpoint-source (NFS) pollution to improve water quality. The two basins are a total of approximately 200 square miles and are primarily underlain by carbonate bedrock. Land use is predominantly agriculture. The most common agricultural NFS pollution-control practices implemented in the Pequea Creek and Mill Creek Basins are barnyard-runoff control and Streambank fencing. To provide land managers information on the effectiveness of Streambank fencing in controlling NFS pollution, a study is being conducted in two small paired watersheds within the Mill Creek Basin.
