Description of Work U.S. Geological Survey (USGS) will use remote sensing data to establish a baseline understanding of current distributions of invasive wetland plants and then forecast potential invasion corridors. Alterations to the Great Lakes shoreline or water-level patterns associated with global climate change could have significant impacts on the extent and composition of coastal habitat. Low lake levels can expose fertile wetland bottomlands to invasive species such as common reed ( Phragmites). Goals & Objectives Goals: Identify current Phragmites distribution in the Great Lakes coastal zone, detect potential areas vulnerable to invasion due to influences such as altered water levels, nutrient and...

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.

Description of Work Past water-quality issues in the St. Lawrence River at Massena, NY resulted in a determination that selected beneficial uses may be impaired in a surrounding Area of Concern (AOC) and on the Canadian side of the international boundary (Cornwall, Ontario). The plankton (phytoplankton and zooplankton) Beneficial Use Impairment (BUI) was so designated because impairment metrics were unavailable or inconclusive. Recent investigations, however, suggest that plankton communities are relatively healthy and no longer threaten the local ecosystem. Thus, the BUI for plankton may now be outdated in all, or parts of, the St. Lawrence River in the Massena AOC. The primary goal for the Massena (and Cornwall)...
