Fall jig bite builds as river water settles near 60

What's biting

What's next

Water in the upper 50s to low 60s should drift down a degree or two over the next few days if nights stay cool. Gauge 04118564 already reads 60°F. As temperatures fall, expect fish to slow down and hold tighter to structure, so slower jig presentations and patient retrieves should outperform fast search baits. Tactical Bassin's fall advice fits this: pitch jigs to hard cover, then work soft jerkbaits or topwater shallow when the sun is low.

Fishing the Midwest notes that fall gamefish often relocate to the green, living weeds as other weed beds die off and oxygen drops. Look for that remaining green cover near river mouths and backwaters.

Today's New Moon means dark nights. Many anglers treat first and last light as the best windows around a new moon, so plan dawn and dusk sessions. Flow at gauge 04119000 is well above the trickle at gauge 04108862 (6.69 cfs), so conditions will differ a lot between nearby waters. Check the flow trend before you commit to a spot, and work seams and eddies where current breaks.

Context

Mid-October is the heart of the fall transition for Michigan's Lake Michigan shoreline and Grand River mouth. Surface water cools through the 50s, baitfish move toward river mouths and sheltered water, and predators follow them. Readings near 60°F put this week roughly on schedule for the season, neither unusually warm nor early to cool. Smallmouth Bass typically begin shifting from shallow summer haunts toward rockier, deeper structure as water temperatures fall toward the 50s. Tributary and river-mouth fishing for trout typically improves as temperatures drop. Always check current state regulations for seasons and limits before harvesting.
