Invasive zebra and quagga mussels (Dreissena polymorpha and D. rostriformis bugensis, respectively) are causing significant ecological and economic impacts and the scope of these impacts has increased as they continue to spread across North America. The USGS conducts science to inform management actions for controlling and mitigating the impacts of invasive mussels. Studies...
Since their introduction in the 1960’s, grass carp (Ctenopharyngodon idella) have spread across the North American continent as far north as the U.S./Canadian border in the Great Lakes. Grass carp are an herbivorous species and can significantly reduce the amount of macrophytes and other plant material in a body of water. Subsequently, this can lead to many detrimental effects for...
The goal of the study is to determine how stream...
The glacial aquifer system is present in parts of 26 states and is subject to a range of climatic conditions from humid to semi-arid. Groundwater availability in the system may be constrained by climatic conditions, poor water quality, hydrogeology, concerns of conflicts with current groundwater users, or the desire to maintain or restore environmental streamflows.
The Glacial Aquifer...

The U.S. Geological Survey (USGS) Michigan Bacteriological Research Laboratory (MI-BaRL) conducts research on antibiotic-resistant bacteria and their genes. We have concentrated our studies on antibiotic-resistant bacteria of human-health concern, including vancomycin-resistant enterococci, methicillin-resistant Staphylococcus aureus (...
In support of the Michigan Department of Environmental Quality (MDEQ) Water Chemistry Monitoring Project, the USGS Michigan Water Science Center has been collecting long-term water quality data for Michigan's rivers and streams.
The USGS compiles water use information by State including estimated amounts, sources, and categories of use every five years since 1950.
The U.S. Geological Survey, in partnership with the National Park Service began a project in 2012 exploring levels of the algal toxins in surface drinking water and recreational waters in 3 National Park Service Parks: Sleeping Bear Dunes National Lakeshore, Isle Royale National Park, and Pictured Rocks National Lakeshore.
The Molecular Ecology Laboratory applies genetic and genomic technologies to address a variety of complex questions and conservation issues facing the management of the Nation's fish and wildlife resources. Together with our partners, we design and implement studies to document genetic diversity and the distribution of genetic variation among individuals, populations, and species. Information...
Great Lakes Restoration Initiative edge-of-field monitoring focuses on identifying and reducing agricultural sources of excess nutrients which threaten the health of the Great Lakes. The USGS supports these efforts by utilizing edge-of-field monitoring to assess the quantity and quality of agricultural runoff and evaluate conservation practices that aim to reduce sediment and nutrient loss....
Pre-deployment briefing for the Upper Missouri River Pallid Sturgeon Drift Study. Fish biologists and physical scientists from Montana Fish Wildlife and Parks, US Geological Survey, U.S. Fish and Wildlife Service, University of Montana, Nebraska Game and Parks Commission, and US Army Corps of Engineers go over the sample design and assignments.
This is an introductory video to an adaptive management approach for the invasive plant Phragmites australis in the Great Lakes basin. An adaptive management framework is an iterative process of robust decision making aimed at reducing uncertainty over time, for a variety of stakeholders with differing backgrounds and interests, via system monitoring.
