Fishing Platte Lake

Benzie County, Michigan · DNR Survey 2010

Scout's Fishing Notes

Platte Lake offers exceptional smallmouth bass fishing with 76% of fish over the 14-inch minimum and excellent growth rates 0.7 inches above state average. The lake is recognized as one of the better smallmouth bass destinations in northwestern Lower Peninsula. Walleye fishing has improved dramatically since switching to spring fingerling stocking in 2002 - all walleye caught in the 2010 survey were from stocked year classes, averaging over 20 inches with 96% legal size and growth rates 1.5 inches above average. Rock bass dominate the fishery by numbers, comprising 64% of the catch, with many exceeding 11 inches and qualifying for Master Angler status. The lake's shallow areas feature sand substrate with gravel shoals in 2-10 feet, while deep areas are marl or muck/marl combination with a maximum depth of 90 feet. Northern pike numbers have declined significantly since the 1970s-80s when fish nearly 40 inches were common; a fish ladder was installed in 2004 to improve spawning access to Deadstream Swamp. Yellow perch suffer from chronic stunting with growth 1.5 inches below average and only 19% reaching keeper size - a problem documented for decades. The lake connects to Lake Michigan via the Platte River, allowing access for steelhead, salmon, and other migratory species. Heavy shoreline development with 34 docks per mile creates good structure but reduces natural woody debris. Water quality remains excellent with low phosphorus (10-11 µg/l) and nitrogen levels, plus good clarity at 6.7 feet Secchi depth.

Overall QualityGenerally healthy gamefish populations with excellent smallmouth bass fishing and good walleye fishing dependent on stocking. Quality varies by species with some stunted populations like yellow perch.

Ice Fishing

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.

DNR Management Direction

Continue walleye stocking at 50/acre (125,800 fish) every other year starting 2011 with spring fingerlings. Monitor with fall electrofishing surveys. Native species like bluegill, pumpkinseed, rock bass, and smallmouth bass should thrive without direct management. Protect remaining riparian wetlands critical to lake health.

Frequently Asked Questions

What fish are in Platte Lake?

Platte Lake is connected to the Platte River, one of Michigan's premier salmon rivers. Coho and chinook salmon stage in the lake during fall runs. The lake also holds smallmouth bass, largemouth bass, panfish, and pike. The clear water and sandy bottom create good smallmouth habitat.

Can you ice fish on Platte Lake?

Platte Lake does freeze in winter and ice fishing is possible, though always check current ice conditions before heading out. The lake's connection to the Platte River means some areas near inflows and outflows may have thinner ice.
