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.

Variable phenology but consistent loss of ice cover of 1213 Minnesota lakes
Lake ice cover is declining globally with important implications for lake ecosystems. Ice loss studies often rely on small numbers of lakes with long-term data. We analyzed variation and trends in ice cover phenology from 1,213 lakes over 74 years (1949-2022) in Minnesota (USA), during which ice cover duration declined at a rate of 2 days per decade (14 days total) and became more...
Management strategy evaluation to assess trade-offs associated with invasive Blue Catfish fisheries and predation impacts
ObjectiveMany species are intentionally introduced beyond their native range to provide benefits to humans (e.g., food, recreation, or biocontrol). However, introduced species can become invasive and can harm native species, prompting resource managers to explore options to simultaneously conserve native biota and enhance fishing opportunities. Management of Chesapeake Bay Blue Catfish...
Sea Lamprey control reduction during the COVID-19 pandemic corresponds to rapid increase in Sea Lamprey abundance
The Sea Lamprey Petromyzon marinus control program in the Laurentian Great Lakes is one of the longest-running and most successful invasive species suppression programs in the world. Although several techniques are used to suppress Sea Lamprey, the control program relies heavily on regular application of lampricide to kill stream-dwelling larvae. The COVID-19 pandemic disrupted...

Improve Control Efficiency Through Better Understanding of Grass Carp Movements and Habitat Use
The goal of this project is to address the threat of invasive Grass Carp by developing a comprehensive understanding of seasonal movements, habitat use, and areas of aggregation to determine when and where eradication efforts would be most effective.
Identifying Spawning Tributaries and Specific Spawning Areas of Grass Carp
Grass carp ( Ctenopharyngodon idella) is an invasive species translocated to the United States in the 1960s due to its potential for nuisance aquatic vegetation control. Following escapes, authorized stockings, and unauthorized stockings, the grass carp range rapidly expanded in the U.S.
