Description of Work Predictive models have been used at beaches to improve the timeliness and accuracy of recreational water-quality assessments over the most common current approach to water-quality monitoring, which relies on culturing fecal-indicator bacteria such as Escherichia coli (E. coli.)

Description of Work The Great Lakes ecosystem has undergone major changes over the last two decades related to the invasion of Dreissenid mussels, increased water clarity, increased benthic algae and associated water quality problems. For reasons not yet entirely understood, and that have bi-national significance, water column total phosphorus has not significantly increased over the last decade but the relative percent of the more biologically available dissolved phosphorus has increased. The filtering action of Dreissenid mussels has been shown to increase concentrations of dissolved phosphorus in the water column immediately above mussel beds and this had been hypothesized as one explanation for the increase...

Description of Work This project is designed to (1) collect more frequent total suspended sediment (TSS) and total phosphorous (TP) data for the Genesee River Watershed, especially sub-watersheds at the 12-digit HUC (Hydrologic Unit code) scale, both within and outside of the AOC; and (2) to conduct a pilot study capable of evaluating the reduction in sediments and nutrients from the current and proposed GLRI non-point source reduction projects in the watershed aggregated at the 12-digit HUC. This project is envisioned as a two-year pilot for the Genesee River Watershed, with potentially wider applications in the Lake Ontario Basin and other Great Lake areas.
