Cooling rivers set up a fall smallmouth window in NH

What's biting

What's next

Expect the water to keep drifting down through the weekend if nights stay cool. Smallmouth typically respond by stacking up near current breaks, deeper pools and rock transitions, and feeding harder through the warmest part of the afternoon than at dawn. Plan the main effort for midday to mid-afternoon, when the water has gained a degree or two.

Low flows at all four gauges mean clear water, so lighter line and natural colors usually outperform flashy presentations in the shallows. Tactical Bassin (blog) highlights an overlooked shallow approach for October bass, using jigs, soft jerkbaits and topwater around subtle cover, and that fits with fish still willing to feed up in skinny water on stable afternoons.

Walleye anglers working the lake should think slow and near the bottom. Fishing the Midwest describes a plain bottom-bouncer and nightcrawler rig as a dependable cool-water producer for fall walleyes, a rig that translates well to any deep structure edge. Waxing crescent moon means darker evenings, so low-light bites around dusk are modest rather than dramatic.

Context

Mid-October in southern and central New Hampshire is typically the back half of the fall transition. Weed beds are dying back, baitfish concentrate, and gamefish relocate toward remaining green cover and deeper structure. Fishing the Midwest notes that finding living green weeds is often a good starting point as waters cool. Water at 53°F sits right on schedule for the season, and the next few weeks usually bring a steady slide toward winter patterns. Check state regulations before keeping any fish.
