Pleiness Lake — also known as Lost Lake — is a small natural lake in Eden Township, Mason County, tucked into the northwestern Lower Peninsula. At roughly 1.9 miles of shoreline, it's a compact, quiet water with a maximum depth of 38 feet and an average depth of just 9 feet. That shallow average means the lake warms up fast in summer and freezes reliably in winter. Locals describe it as one of the most peaceful lakes in Michigan, with bald eagles, cranes, and plenty of wildlife along the undeveloped stretches of shore.
There's one public launch on the lake, and a beach area also goes by the Lost Lake name. The shallow, weedy profile creates solid warm-water fish habitat — expect panfish and bass in the shallows, with the deeper 38-foot hole potentially holding some cooler-water species. Whiskey Creek Campground and Whelan Lake Area are both nearby, making this a good base camp lake for a quiet northwest Michigan getaway without the resort-town crowds.
