Description of WorkThe Great Lakes Restoration Initiative (GLRI) was established to accelerate ecosystem restoration in the Great Lakes by confronting the most serious threats to the region, such as nonpoint source pollution, toxic sediments, and invasive species. Four Priority Watersheds have been targeted by the Regional Working Group's Phosphorus Reduction Work Group (Fox/Green Bay, Saginaw, Maumee, and Genesee) and are characterized by having a high density of agricultural land use and have ecosystem impairments that have been clearly identified. Monitoring is being conducted at the sub-watershed, edge-of-field, and subsurface-tile scale where monitoring locations are targeted to those areas within each watershed...

Description of Work USGS scientists will develop support to State partners for the removal of Beneficial Use Impairments (BUIs) such as fish consumption advisories, fish tumor presence, Eutrophication and unwanted algae, drinking water problems, beach health, and concentrations of PCBs in lake trout and walleyes. Areas of Concern (AOC) principles and guidelines were developed as an initial reference point from which appropriate restoration criteria could be developed. Stage 2 Remedial Action Plans (RAPs) were developed for each of these AOCs to address impairments to any one of 14 beneficial uses associated with these areas. Specific remediation actions are completed in order to restore the beneficial use. When...

Description of Work U. S. Geological Survey (USGS) will identify through this project significant sources and impacts of historical and newly emerging toxics to the Great Lakes ecosystem through broad surveillance as well as laboratory and field research of tree swallows and other bird species. USGS scientists will determine the amount of exposure to and the effects of historical and emerging contaminants in Great Lakes food chains. The data will inform regulators and provide guidance on removal of Beneficial Use Impairments at Area of Concern sites around the Great Lakes. Work supported under this project is quantifying exposure to, and effects of, both historical and emerging contaminants on Great Lakes food chains...
Description of WorkExcessive nutrient and sediment concentrations and loads have been documented in many tributaries to the Great Lakes. Many efforts have been made during the first 5 years of GLRI to reduce nutrient and sediment concentrations in streams and rivers throughout the Great Lakes Basin, and these efforts will continue during Phase II of GLRI. In order to determine the success of these efforts at improving water quality, it is important to document in a systematic manner the water quality and loading from key tributaries to the Great Lakes.Goals & ObjectivesThe objectives of this project are to: 1) Collect streamflow and samples for sediment and nutrients for major streams that are tributary to the Great...

Description of Work The Great Lakes Restoration Initiative (GLRI) was established to accelerate ecosystem restoration in the Great Lakes by confronting the most serious threats to the region, such as nonpoint source pollution, toxic sediments, and invasive species. Three Priority Watersheds have been targeted by the Regional Working Group's Phosphorus Reduction Work Group (Fox/Green Bay, Saginaw, and Maumee) and are characterized by having a high density of agricultural land use and have ecosystem impairments that have been clearly identified. Within the Fox River Priority Watershed, monitoring is being conducted at the sub-watershed and edge-of-field scale. The edge-of-field stations are targeted to those areas...
