Braddock Bay currently is undergoing a major habitat restoration project that is expected to be complete in 2017. One of the issues raised in the evaluation of restoration options was how would the on-going release of phosphorus into the Bay from the five sub-watersheds that drain into it affect the water quality in the Bay once the restoration work is complete. An evaluation of the sources of phosphorus into the Bay had not been done. The Monroe County Department of Environmental Services (DES) has quantified the relative contribution of most of the watersheds within the County to overall phosphorus loads except those that drain into Braddock Bay. Based upon that information DES recommended that a study be conducted to determine distribution of pollutant loads which would become the basis for determining further management actions.
The relative contribution of a variety of sources that discharge phosphorus into the five sub-watersheds that drain into Braddock Bay was estimated using MapShed modeling software. The Salmon Creek and Brockport-Otis Creek HUC12* watershed accounted for most of the phosphorus loads to the Bay. Streambank erosion, septic system failures, hay/pasture management, and farm animal management were identified as the major contributors to those loads. Recommendations were made for further study.
