Great Lakes Connecting Channels

This layer was created in 2018 using ArcGIS 10.5. The layer uses the shoreline of the 10-minute grids (v3), with divisions between the Great Lakes and connecting channels based off of: Michigan waters 1. Descriptions in the 2000 Consent Decree for the boundaries between the St. Mary’s River and Lakes Huron and Superior, and the boundary between Lakes Michigan and Huron. 2. The description in Fisheries Order 200 for the boundary between the St. Clair River and Lake Huron. 3. The description in Fisheries Order 242 for the boundary between Lake St. Clair and the Detroit River boundary 4. Descriptions in the Michigan Fishing Guide 2016-2017 for the boundary between the Detroit River and Lake Erie. 5. Boundaries in the 1:24,000 National Hydrography Dataset (downloaded 2012) for the boundary in Michigan waters between Lake St. Clair and the St. Clair River. Canadian waters 1. Descriptions in the Ontario Recreational Fishing Regulations 2017, Zone 19 for the boundaries in Canadian waters between the St. Clair River and Lakes Huron and St. Clair, and the boundaries between the Detroit River and Lakes St. Clair and Erie. This layer was created to be used in conjunction with the 10-minute grid layer, and as such uses the same shoreline and includes Canadian waters of Lake St. Clair, the Detroit River, and the St. Clair River.
