Description of Work Since 2010, connecting channels have been included in each of the Great Lakes’ Lake Management Plans (LaMPs). Lake Ontario now includes both the Niagara River and the St. Lawrence River. The Niagara River is well characterized by a number of long-term programs, but because of the lack of tributary water-quality data, the St. Lawrence River and its tributaries constitute a data gap in the information needed for the Lake Ontario to fulfill its goals. Critical information needs, including basic water-quality parameters, total suspended solids, nutrients and flow data. These data are needed to aid in the identification of sources of nutrient and sediment loading to the St. Lawrence. The monitoring...

Description of Work USGS scientists provide expertise, capacity and support for the implementation of Lakewide Management Plans (LaMPs) and the associated goals, objectives and targets for each of the Great Lakes, including Lake Superior. The LaMPs are critical binational groups that are important for promoting Great Lakes restoration. Specifically, LaMP efforts include compiling monitoring and research information into the Great Lakes web mapper (SiGL Mapper). The Mapper’s focus is on information that will result in recognition of areas where data are being collected, missing or sparse, and on areas where ecosystems are vulnerable.

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...
