The Platte River flows into and out of Platte Lake on its way to Lake Michigan at Platte Beach. This river is one of Michigan's most important Pacific salmon streams — the DNR's Platte River State Fish Hatchery is upstream, and coho and chinook salmon migrate through the lake during fall runs. The lake is also close to Crystal Lake and Big Platte Lake, all part of the broader Benzie County watershed.
Platte Lake freezes in winter and supports ice fishing, but use caution near the Platte River inlet and outlet — current flow keeps ice thinner in those areas. Always check local ice reports before heading out.

Platte Lake sits in Benzie County just inland from Sleeping Bear Dunes National Lakeshore — roughly 2,600 acres of remarkably clear water with a sandy bottom. Reviews consistently describe the water as "crystal clear" and "unbelievably clean," which tracks with the oligotrophic lakes typical of this glacial terrain. The west end features a well-known sandbar that draws boaters and swimmers in summer, creating a social scene on the water. The lake has both shallow wading areas and deeper sections suitable for water skiing and tubing.
The Platte River — famous as one of Michigan's most important coho and chinook salmon runs — flows through here on its way to Lake Michigan at Platte Beach. That connection means Platte Lake sees salmon staging in fall and steelhead moving through in spring. There's one public launch with a single-lane ramp, small parking lot, and seasonal restrooms. It handles smaller to mid-size powerboats fine, but expect to wait during peak weekends — you're launching and loading one boat at a time. The surrounding area is stacked with attractions: Sleeping Bear Dunes, Crystal Lake, and Traverse City are all within easy reach.
