Hamlin Lake home appraisals

Hamlin Township

Hamlin Township's median owner value was $281,400 in the 2020 to 2024 survey, according to Census Reporter, and Hamlin Lake explains much of that. The dammed lake covers about 4,990 acres and runs roughly 12 miles. Ludington State Park sits between the lake and Lake Michigan, which keeps a long stretch of shoreline out of private hands.

Two basins split by the narrows

Hamlin Lake forms where a dam backs up the Big Sable River before it reaches Lake Michigan. The western basin reaches about 80 feet deep and the eastern one about 34, with the narrows between them. The first dam powered a sawmill in the 1850s. A wooden dam failed in 1888 and flooded the town of Hamlin, and a 1912 rebuild failed too. A lake sale is worth reading for which basin it sat on.

A wooden dam gave way in 1888 and flooded the town of Hamlin.
