Fall Bite Bonanza on the St. Clair Flats

Artificial Lure reporting live for October 18th, 2025, with your Lake St. Clair fishing report. The sun cracked the horizon at 7:44 AM this morning, with sunset coming up at 6:48 PM. Weather is classic mid-October: mid-50s at dawn, peaking around the low 60s by mid-afternoon, with winds out of the south at 10 to 12 knots. Skies are partly cloudy, making for comfortable, brisk casts and a solid chop on the open water. Water temperatures are hanging at 60 degrees Fahrenheit, so bring a light jacket and keep your hands dry between bites—fall on the St. Clair flats will chill you quick, even during the bite windows, which are prime this morning from about 8 to 10 and again after dinner from 8:30 to 10:30, per FishingReminder. Today’s moon is a waning crescent, setting up lower light for the early bite. There’s no meaningful tidal swing here, but water levels are holding steady and clarity is above average—expect some weed drift in the shallows. Fishing’s been heating up the past few days, especially for big fall walleyes. According to the Lake St. Clair Michigan Fishing Report on Spreaker, jiggers working the shipping channel edges and the mouth of the Detroit River have pulled nice limits at first light and just before dark. Jigging Rapalas and 1/2 oz hair jigs tipped with shiners are the ticket for walleyes, while deeper water is still good for trolling with crawler harnesses and bottom-bouncers. Perch action continues to impress, especially at L’anse Creuse Bay and near the 400 Club. Reports from the docks and boats mention hand-sized slabs being hauled up on minnows and small plastics, particularly Chartreuse or Motor Oil colored drop-shot presentations. The Jefferson Beach Marina basin is producing decent numbers right now if you’re after an easy launch or shore spot; L’anse Creuse and Campau Bay have been especially productive for both perch and bonus smallies. Muskie chasers: now’s the time. Several double-nickel fish have been boated this week trolling 8-12” crankbaits and large rubber baits, especially black, white, or perch patterns. Focus your efforts south and east of Grassy Island, and out from Mitchell’s Bay if you’re ready to cross. The pros recommend varying your trolling speed in these cooler fall waters—to 4 or 4.5 mph—for more vicious strikes. Also, the shallower edges near Stoney Point have produced for casting magnum Bulldogs and bucktails, especially on the windblown side. Bass anglers are still finding good numbers—mostly smallmouth—along the drop-offs and rocky humps, with Ned rigs, tubes in natural goby, and green pumpkin craws doing work. Don’t ignore the Milk River mouth or the scattered points north of Harsens Island. For bait, live emerald shiners and large golden shiners are the top natural picks; hot artificial lures right now are Fire Tiger, Perch, and Gold patterns for crankbaits, and anything with flash for spinner rigs and blade baits.
