Summary
This data contains coordinate locations for suspected historical spawning locations of lake whitefish (Coregonus clupeaformis) and cisco (Coregonus artedi) across the Lake Erie basin, including the Detroit River, Lake St. Clair, and the St. Clair River. Data points were summarized using ArcGIS 10.5. Data came from published and unpublished sources cited in the Atlas of the Spawning and Nursery Areas of Great Lakes Fishes (Goodyear et al. 1982) and other sources as described. Data points included were specific locations described as having the presence of eggs or spawning fish. Pseudo-absence data used for comparison purposes are also provided in this data release.

Data were collected and plotted on maps to bring all historical data into one location and to compare historical spawning locations of lake whitefish and cisco to contemporary egg and larval sampling locations (not included in this data release).
