Merrimack smallmouths turning on spinnerbaits and topwater

What's biting

What's next

Conditions are moving toward the fall feed. As water cools, smallmouths typically feed more aggressively and roam shallower edges, so the shore bite should hold over the next few days if nothing changes sharply. We have no wind or sky data for this run, so check the local forecast before heading out. A waning crescent moon means darker nights, so the best action is likely at first light and in the last hour before dark. Bring a range of retrieve speeds: a steady spinnerbait pass covers water quickly, and a slower topwater cadence works when fish are holding tight to cover.

Context

Early October is a typical point in the New England fall smallmouth cycle. Water cools through the month, baitfish concentrate, and bass feed heavily ahead of winter. Larger New Hampshire lakes, Winnipesaukee among them, commonly turn over in the fall, which mixes the water column and can scatter fish for a few weeks before they settle into deeper cover. A bite that is already active on the Merrimack this early in the fall is a normal, on-schedule pattern. Check current NH fishing regulations before harvesting any fish.
