Lake Diane is a small lake in Hillsdale County in Michigan's southern tier, popular as a family vacation destination. The lake has a single DNR boat launch — a small, well-maintained two-lane ramp with an outhouse — that reviewers note can get busy, especially around holidays. The lake community is tight-knit and puts on impressive Fourth of July fireworks that draw attention from visitors.
Fishing-wise, Lake Diane has a reputation as a musky spot, which is notable for a smaller southern Michigan lake. Reviewers also mention general fishing success. The lake bottom reportedly has stumps and a mucky character in places, so watch your prop in the shallows. Several rental properties and retreats line the shore — Lake Diane Retreat is particularly well-known for multi-generational family reunions — and there are campgrounds nearby including Lake Diane Retreat, Castaway Campground, and Bluffs. The surrounding Hillsdale County countryside is quiet and rural, described by visitors as a "very pretty part of the country."
