 Ohio Coastal Atlas Project
Lake Erie and its Watershed
The Map Library and GIS products are part of the Ohio Coastal Atlas suite of mapping resources developed to provide coastal decision-makers, professionals, educators, interest groups and the public with information about Lake Erie and its watershed.
A selection of maps and graphics that focus on Lake Erie and the Lake Erie Watershed which have been used in various OCM applications and/or created for our partner agencies needs are available below to download as PDF files.
While some maps are created to print at a variety of sizes including large poster format, most map files linked below scaled to print on 11x17 paper. Your printer settings can be adjusted to print the maps on other standard paper sizes. An interactive map viewer with many data layers is accessible by selecting "Create." Topic-specific, interactive Use Case Map Viewers is accessible by selecting "Expand."
For additional and/or higher resolution maps, please contact the Office of Coastal Management.
Each of the 164 public access locations in the 8 coastal counties along Ohio’s 312-mile coast are mapped. Link above is for print on 11x17-inch paper. For other map size options, visit the Lake Erie Public Access Guide page.
