Survey readout
Munising Bay is mapped to a depth of 88 ft on the NOAA NCEI survey and covers about 5,713 acres in Alger County, Michigan. Coverage is sparse: about 63% of this lake lies well away from any surveyed contour, so most of the shape shown there is interpolated between distant measurements rather than mapped.
Derived from NOAA NCEI Great Lakes bathymetry data.
The maximum depth and the “deepest” marker describe Munising Bay itself. The map also renders the surrounding open-lake water inside the frame. Depths in that water reach about 469 ft.

Treat these as graves. Lives were lost on many Great Lakes wrecks, including 2 recorded here, and human remains may still be present. Michigan’s bottomlands also hold submerged cultural sites that long predate these ships. Look, photograph, and leave everything exactly as you found it.
Removing or disturbing wreckage on Great Lakes bottomlands is a felony under Michigan Part 761, 1994 PA 451, at a fair market value of $100 or more. Positions are historical reference only — not navigation, and not dive-planning data. Wreck records are published by the Michigan Underwater Preserve Council, which publishes a guide to the Alger preserve.
