Bismarck Conservation Area grew around a lead-mining reservoir

Bismarck Conservation Area is a Lead Belt story hiding in plain sight. MDC describes a 1,188-acre area around DiSalvo Lake, which was built in 1944 by the Hanna Mining Company as a reservoir for nearby lead-mining operations.

Now the same landscape works as public conservation land. MDC describes upland forest, wet-mesic bottomland forest, and an igneous glade and savanna complex under restoration. DiSalvo Lake adds fishing and water access to the mix.

Check MDC before visiting, especially for fishing, camping, hunting seasons, and any current access limits. Bismarck is shared across county lines, so the agency map matters.

Mining, geology, water, and public land overlap here. The old industrial reason for the lake is part of the story, but the current use is outdoor access and habitat.
