Fall cooldown sets up Wabash smallmouth and Lake Michigan trout
Gauge 03353200 reads 65°F with 12.2 cfs, and gauge 05524500 reads 64°F at 128 cfs, so the water sits in the mid-60s on the day before a New Moon turns the page toward colder nights. Gauge 395223086214202 reports 60°F. That is a comfortable range for Smallmouth Bass, which tend to feed hard as water falls out of the summer peak. Tactical Bassin notes that fall bass hold near hard structure such as dock pilings, laydowns and rocks, and recommends jigs, soft jerkbaits and topwater in shallow water. Fishing the Midwest points to green, living weeds as the first place to look as other weed beds die back.

Expect water temperatures to keep slipping over the next few days if nights stay cool. That should push Smallmouth Bass toward deeper rock and wood, so plan on starting shallow at first light and moving out as the sun climbs. Tactical Bassin's fall finesse advice, tiny topwater and swimbaits plus compact jigs, fits the tougher days when fish turn picky.
The New Moon means dark nights and no moonlight to disturb feeding, so dawn and the last hour of daylight are the windows worth planning around. Gauge 03335500 shows 4,880 cfs on the larger river, a strong flow. Heavy current there calls for fishing eddies and slack seams rather than open channel.

Context
Mid-October in northern Indiana typically falls right on schedule for the fall transition. Summer weed beds are thinning, baitfish are relocating, and predators follow them toward firmer structure. Lake Michigan tributaries typically start to draw trout once temperatures cool, while inland river bass feed up before winter.
