Description of Work USGS will conduct seasonal sampling of benthic invertebrates, zooplankton, prey fish, and their diets to complement the seasonal lower trophic level sampling by EPA. A point of emphasis is describing the vertical distribution of planktivores and their zooplankton prey, to fill a knowledge gap on these predator/prey interactions. These data will provide a more holistic understanding of how invasive-driven, food-web changes could be altering energy available to sport fishes in the Great Lakes and used to build bioenergetics models that can evaluate whether zooplankton dynamics are being driven by limited resources or excessive predation. Understanding the key drivers of zooplankton will provide...

Description of Work USGS will conduct monthly samples of benthic invertebrates, zooplankton, and water quality as well as seasonal sampling of fish and fish diets. This project supports lower trophic sampling in Lake Erie and understanding food webs. An emphasis will be collecting samples from a nearshore to offshore design.

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 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 U.S. Geological Survey (USGS) scientists are focusing on restoring natural water flow and ecological processes between coastal wetlands in the Ottawa National Wildlife Refuge (Ohio) and adjacent to Lake Erie to improve fish and wildlife habitat. This pilot project will develop approaches that will restore coastal wetland function and increase ecosystem resilience to be used as a model throughout the Great Lakes basin. USGS will focus on restoring natural hydrologic processes in diked coastal wetlands adjacent to Great Lakes waters to improve wetland functions like phosphorus retention and restoration of habitats for fish and wildlife. Sustainable approaches are being developed in the Maumee River...

Description of Work USGS will conduct seasonal sampling of benthic invertebrates, zooplankton, prey fish, sport fish, and their diets to complement the seasonal lower trophic level sampling by EPA. This data will provide a more holistic understanding of how invasive-driven, food-web changes could be altering energy available to sport fishes in the Great Lakes and used to build a decision support tool that can explore how different scenarios (dreissenid control, nutrient reductions, changes in fish stocking) influence the biomass of economically important fisheries.

I study biogeochemical cycling in aquatic ecosystems. Current projects include 1) Trends in alkalinity and acidity in coastal rivers of the US and potential effects on coastal acidification (USGS NAWQA Trends Team). 2) Continental-scale synthesis of stream metabolism and its links to water quality and the aquatic carbon cycle (USGS Powell Center; USGS NAWQA; USGS NRP). 3) Carbon transport and cycling in the Upper Mississippi River basin (USGS LandCarbon). 4) Long-term trends in acidification of the Delaware River Estuary (Penn State University). 5) Hyporheic exchange in contrasting headwater streams of the Colorado Front Range (with Colorado School of Mines).

Description of Work USGS scientists are developing science based forecasting tools that capture changes to water flows and discharges of nutrients and sediments to the Great Lakes. The work done by this project provides managers with forecasting tools for predicting the combined effects of climate and land use changes that will help them identify and prioritize the sites best suited for restoration efforts. USGS scientists 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...

Great Lakes Restoration Initiative,
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 Since the early 2000s, the LaMP has proposed adding nutrients (specifically phosphorus) to its “pollutant of concern” list, given that excessive nutrients were believed to cause impairments in the nearshore waters. Since that time, scientists have highlighted the “shunting” of nutrients to the nearshore, owing to the ability of invasive dreissenid mussels to capture some portion of allochthanous phosphorus that enters the lake through tributaries. These changes are believed to underlie a series of changes in the nearshore, including increased biomass of cladophora and hypothesized increases in benthic and pelagic biomass, including zooplankton and fish. As an extension, this model proposes the...

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.
