Great Lakes Commercial Fishing Catches 1929-2014

Since 1971 the Great Lakes Science Center (GLSC), formerly known as the National Fishery Center-Great Lakes (National Biological Service), the Great Lakes Fishery Laboratory (U.S. Fish and Wildlife Service)(FWS/GLFL), and the Ann Arbor Biological Laboratory (Bureau of Commercial Fisheries), have acted as repositories for the processing, reporting, and storage of U.S. Great Lakes commercial fishery

Lake Michigan Fish Acoustic Data from 2011 to 2016

Area backscattering (ABC), mean acoustic size (sigma), and fish density in the intervals and layers of acoustic survey transects of Lake Michigan in the years 2011-2016. The data were collected to provide information on the temporal and spatial dynamics of the pelagic fish community of Lake Michigan. This information is used to provide an understanding of community and population drivers and in a

Western Lake Erie Restoration Assessment Dikes

This dataset is the output of a python script/ArcGIS model that identifies dikes as having a difference in elevation above a certain threshold. If the elevation difference was below a certain threshold the area was not considered a dike; however, if the difference in elevation between two points was significantly high then the area was marked as a dike. Areas continuous with eachother were conside

Saginaw Bay Restoration Assessment Dikes

This dataset is the output of a python script/ArcGIS model that identifies dikes as having a difference in elevation above a certain threshold. If the elevation difference was below a certain threshold the area was not considered a dike; however, if the difference in elevation between two points was significantly high then the area was marked as a dike. Areas continuous with eachother were conside

Connecting River Systems Restoration Assessment Degree Flowlines

This represents the flowline network in Connecting River Systems Restoration Assessment (CRSRA). It is attributed with the number of disconnections between the reach and the connecting river system. These data will help identify the condition of hydrologic separation between potential restoration areas and the connecting river system. Low numbers represent fewer disconnections such as culverts bet

Western Lake Erie Restoration Assessment Composite Model

Well-established conservation planning principles and techniques framed by geodesign were used to assess the restorability of areas that historically supported coastal wetlands along the U.S. shore of western Lake Erie. The resulting analysis supported planning efforts to identify, prioritize, and track wetland restoration opportunity and investment in the region. To accomplish this, publicly avai

Connecting River Systems Restoration Assessment Composite Model

Well-established conservation planning principles and techniques framed by geodesign were used to assess the restorability of areas that historically supported coastal wetlands along the U.S. shore of the connecting rivers (Detroit River and St. Clair River). The resulting analysis supported planning efforts to identify, prioritize, and track wetland restoration opportunity and investment in the r

Lake Erie Fish Community Data

This data is intended for use by Lake Erie fisheries managers, academia, the fishing industry, and the public. The data sets are annually evaluated to provide estimates of abundance of key forage and predator species, to assess seasonal and spatial distributions of fishes, and assess year class strength of key forage and predator species in the western basin of Lake Erie. The data sets are then pr
