Grand River trout and smallmouth get a cooling-water boost

What's biting

What's next

Expect temperatures to keep sliding through the coming week as nights lengthen. The 64°F readings sit in a comfortable range for active feeding, and each degree lost pushes fish to feed harder ahead of winter. Watch for river water to cool a few more degrees, which typically draws Brown Trout and Rainbow Trout up from the lake toward the Grand River system, a classic Great Lakes fall pattern.

A New Moon means dark nights and a strong pull on feeding periods around dawn and dusk. Plan early-morning and last-light sessions, when low light favors both trout moving into moving water and smallmouth cruising shallow cover. Fishing the Midwest notes that fall fish often relocate to the greenest remaining weeds, so check any live vegetation near deeper edges before moving on.

Flows near 1,970 cfs on the Grand mean current breaks and seams matter. Fish the softer water beside faster current, and expect clarity to hold unless a heavy rain event bumps the river. Check state regulations before keeping any fish, as seasons and limits vary by water.

Context

Mid October is typically the heart of the fall transition on west Michigan waters. Lake Michigan tributaries usually see trout begin to stage and run as water temperatures drop into the 50s and low 60s, and smallmouth start shifting from summer haunts toward deeper structure. Current readings look on schedule for the season, with water cooling steadily rather than crashing. Late October into November often brings the strongest river action as temperatures fall further.
