Great Lakes Science Center
Welcome! The Great Lakes Science Center (GLSC) is part of the Midcontinent Region of the USGS, DOI Regions 3 and 5. Our scientists work in the Great Lakes region and other parts of the country to meet the nation’s need for scientific information used by resource managers to restore, enhance, manage, and protect the living resources and habitats in the Great Lakes basin.

Impacts of artificial rearing on cisco Coregonus artedi morphology, including pugheadedness
Cisco (Coregonus artedi Lesueur, 1818) in the Laurentian Great Lakes declined throughout the 19th and 20th centuries. Managers are attempting to restore Great Lakes cisco and other coregonines using multiple approaches, including stocking. A potential obstacle to these efforts is that artificially reared coregonines can display deformities and morphological differences compared to wild fish, but t
First documentation of grass carp spawning in Lake Erie’s Central Basin
Grass carp (Ctenopharyngodon idella) are non-indigenous to North America having been translocated to the United States in the 1960s as a potential non-chemical solution for nuisance aquatic vegetation. Reproductively viable grass carp now exist in many watersheds in the United States. In the Great Lakes basin, grass carp were first discovered in the 1980s with direct confirmation of successful rep
Reproduction of grass carp (Ctenopharyngodon idella) in the Maumee River, Ohio: Part 1—Spawning area identification using bidirectional drift modeling
Control of invasive grass carp (Ctenopharyngodon idella) populations in the Western Lake Erie Basin merits adaptive management guided by the best available science. Presently (2024), capture of mature grass carp in rivers during spawning season is most efficient, so knowing when and where grass carp are spawning is essential information for natural resource agencies. Using bidirectional drift mode

Long-term Monitoring of Great Lakes Coastal Wetlands and Contributions to the Coastal Wetland Monitoring Program
The Coastal Wetland Monitoring Program (CWMP) is an EPA-led program to monitor the health of all Great Lakes coastal wetlands larger than four hectares. USGS scientists are working with Principal Investigators from many State and academic institutions to conduct data collection, implement standardized sampling protocols, analyze multiparameter data, and communicate results to the public.
Invasive Phragmites Science: Using Microbial Interactions to Foster the Restoration of Great Lakes Wetlands
The USGS is developing innovative Phragmites control measures to keep this rapidly spreading invasive plant from further expanding its range into new wetland habitats and to aid in the development of successful restoration strategies. Scientists are conducting studies and field tests to determine (1) if microbes (i.e., fungi and bacteria) that live within and around Phragmites are enabling the...
Restoring Wetland Habitat and Function at the Shiawassee National Wildlife Refuge
Hydrologic connectivity is essential to maintaining coastal wetland services and functionality. Impounded wetlands often do not provide essential services such as flood mitigation and nutrient retention, nor can they be utilized as spawning and nursery habitat by important Great Lakes fishes. The Shiawassee National Wildlife Refuge manages hundreds of acres of historical coastal wetland habitat...
