Navigation Structures at Pentwater Harbor

The Navigation Structures at Pentwater Harbor are navigational structures located at the west end of Lowell Street in Pentwater, Michigan. They were listed on the National Register of Historic Places in 2001.
In 1855, Charles Mears constructed a 70-foot-wide channel from Pentwater Lake to Lake Michigan, lined with timber cribbing, to accommodate his lumbering interests. In 1858, he built a pier extending over 600 feet into Lake Michigan where ships could dock. Additional pier structures were built to line the channel. The first incarnation of the channel was relatively shallow, but Mears continued to improve it, and by 1865 it was deep enough that a lake-going steamer, the Daylite, was able to sail into Pentwater Lake.
