Description of Work Benthos (benthic invertebrate) and plankton (phytoplankton/zooplankton) communities in Wisconsin's four Lake Michigan Areas of Concern (AOCs; Menominee River, Lower Green Bay and Fox River, Sheboygan River, and Milwaukee Estuary) and six non-AOCs will be quantified. The inclusion of non-AOC sites will allow comparison of AOC sites to relatively-unimpacted or less-impacted control sites with natural physical and chemical characteristics that are as close as possible to that of the AOCs. The community data within and between the AOCs and non-AOCs will be analyzed. This project is a cooperative agreement between the Wisconsin Department of Natural Resources (WDNR) and the US Geological Survey (USGS)....

Description of Work To date many meetings have been attended and coalitions developed between USGS Water Mission area and NYSDEC and EPA region 2 which have spun off into several other monitoring and BUI delisting projects funded by Region 2 through the USGS/EPA IA. This has been a perfect example of leveraging USGS GLRI funds to develop additional GLRI-related program for the Lake Ontario LaMP partners, especially for tributary nutrient and sediment loading to Lake Ontario and helping collect and assess the data needed to remove BUI impairments at the Rochester Embayment and St. Lawrence/Massena AOCs for benthos and phytoplankton impairments.

Description of Work Participation on the Lake Erie Lakewide Management Plan Workgroup and related subcommittees such as toxics, sources and loads, nutrients, and biodiversity. Attend meetings and conferences associated with LE LAMP activities. This includes The Lake Erie Millennium Network, CSMI, Ohio Phosphorus Task Force, and other meetings or workshops addressing nutrient and toxicity issues in Lake Erie. Communicate USGS activities in the Lake Erie Basin that can influence understanding or impact decision making.

Description of Work The study will be implemented in two phases due to logistical constraints and the need to incorporate methods developed (and findings) from a comparable investigation underway in another AOC. The first phase will consist of site selection, methods refinement, work-plan development, subcontract assembly, site reconnaissance, and sediment collection which will be done mainly during FY2013. The second phase will consist of macroinvertebrate identification, sediment toxicity testing, data analysis and interpretation, and report preparation and review mainly during FY2014. In brief, we will generate bed sediment toxicity and benthic community data needed to test two related hypotheses that address...

Description of Work This study will generate bed sediment toxicity and benthic community data needed to test two related hypotheses that address the two criteria for delisting the benthos BUI. The first hypothesis is that bed sediments at selected sample locations in the AOC (in three tributaries and in the St. Lawrence River) are no more toxic to the test species than bed sediments collected from control sites located outside (generally upstream from) the AOC. Acute (survival) and chronic (growth) whole bed-sediment toxicity tests will be conducted using the midge (Chironomus dilutus), following standard methods (USEPA 1994; USEPA 2000). The second hypothesis is that the benthic macroinvertebrate communities from...

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)...
