Fall stocking and cooling water set up Merrimack trout and perch

What's biting

What's next

Expect water temperatures to keep sliding a degree or two over the coming days if nights stay cool, which pushes bass toward slower retrieves and tighter structure. Low flows mean clear, settled water, so lighter line and natural colors should help in the river sections.

Tactical Bassin points to shallow jigs, soft jerkbaits and topwater as overlooked fall tools, and the Fishing the Midwest write-up notes that green, living weeds tend to hold fish as other weed beds die back. Those are general fall patterns rather than local reports, but they fit the conditions on the water now.

The moon is a waxing crescent, so evenings are only lightly lit. Plan for early morning and the last hour of daylight, when cooler water makes fish most willing to feed. Midday sun can warm the shallows by a degree or two and briefly turn the bite on.

Context

Mid October is on schedule for a Merrimack and Winnipesaukee fall transition. Surface water is typically cooling out of the 60s into the low 50s, weed growth is fading, and fish begin relocating toward remaining green cover and baitfish. Stocked trout add a reliable option for shore anglers, and perch and smallmouth often bunch up as the season closes. Check current state regulations and stocking updates before heading out.
