Published Jan. 11, 2024

Chippewa Harbor is located in Isle Royale, MI in Keweenaw County (National Park) on Lake Superior. The Project was authorized by the Rivers and Harbors Acts of March 2, 1945. The existing project provides for an entrance channel 75 feet wide and 14 feet deep, connecting the outer and inner harbors.  The Harbor is subject to extreme fluctuations of water level for a temporary nature, due to wind and barometric conditions. Fluctuations vary from 1 foot above the mean lake level prevailing at the time. The harbor services primarily recreational navigation interests.
