Artificial Lure here and it’s a fresh Lake St. Clair fishing report for August 15th, 2025. We’re heading into late summer with classic Michigan weather: a cool morning around 65°F, calm to light SSW winds, and patchy clouds in the forecast. Expect air temps to push into the mid-70s by midday. According to NOAA, sunrise hit at 6:33 AM, with sunset due in at 8:38 PM. There's no significant tidal activity on St. Clair, but wind-driven currents from the southwest could make for active fish near shorelines and river mouths.

The bite’s been strong this week, especially after the recent Bassmaster Elite and Open tournaments wrapped up just days ago. Tournament anglers hammered solid bags of smallmouth, including multiple 4- and 5-pound class fish. Evan Kung hauled in over 20 pounds on the final day, and several pros cracked the 23-pound barrier earlier in the week near Anchor Bay and Harley Ensign. According to Bassmaster.com and the pros themselves, smallmouth schools are size-specific: if you’re only getting 3-pounders, move and find those big class groups that seem to hang tight to each other.

Most action’s been on sand and grass edges just off primary drop-offs—these transition zones are loaded with bait, and that’s where the predators are. On Instagram this week, locals have been showing off big smallmouth caught on finesse baits: ned rigs, green pumpkin tubes, and drop shots rigged with 3–4 inch baitfish imitations are producing when twitched over mixed grass and sand. If you’re more into chucking hardware, crankbaits in shad patterns and compact swimbaits on light heads are putting fish in the well. Early and late in the day, topwater walkers and poppers are also drawing explosive strikes tight to weed beds, especially if you spot bait dimpling the surface.

If you’re eyeing other species, the DNR and Lake St. Clair charters report steady catches of musky and walleye. Trolling deep crankbaits and large rubber baits for musky, especially off the river mouths and in the South Channel, has been productive. Walleye are mixed in and hitting nightcrawler harnesses behind bottom bouncers, especially in the evenings near the St. Clair River inlet and over the dumps.

Yellow perch have started to group up on the mid-lake humps around the 11–16 foot range, taking live minnows and small jigs. With over 19 million fish stocked across Michigan this year—the DNR calls 2025 a “banner season”—expect perch and walleye numbers to keep improving into fall.

Hot spots for the day:
- Anchor Bay’s eastern grass lines and the Harley Ensign area for smallmouth.
- Mile Roads, especially near 9 and 400 Club, are producing multi-species bags.
- Try the mouth of the Thames River for mixed bag action—walleye, bass, and pike are cruising these flows.
- Sturgeon anglers are working deeper holes off the Belle River Hump with cut bait after dark and connecting with giants.

Locals have mentioned a slight uptick in algae here and there, and there’s an $800K trial happening to beat back muck and invasive growth thanks to Rep. St. Germaine’s push. It hasn’t affected most main-lake fishing, but you may notice some cloudy patches near shoreline access—shift to deeper grass if the water’s too murky.

Bring sunscreen, a good pair of polarized glasses, and plenty of water. Live bait is a winner for perch and walleye today, but for trophy smallmouth, finesse plastics in goby or shad pattern are getting it done. If you’re musky hunting, big blades and rubber remain king. Don’t forget your license—DNR wardens are present this summer.
