Lake Michigan dominates this coastal survey, which covers a vast offshore expanse east of the Wisconsin shoreline. While primarily a maritime chart of open water, it serves as a precise cartographic record of the lake’s bathymetric and navigational surface context during the early twenty-first century. This edition, produced by the U.S. Geological Survey, utilizes imagery from the June 2013 National Agriculture Imagery Program to maintain accuracy. The map provides essential coordinate data for the waters just off Port Washington, supporting modern hydrographic study and regional planning along the Ozaukee County coast.
