Fall trout and perch bite builds as NH waters cool

Water in the Merrimack and Lake Winnipesaukee area is sitting in the high 40s to low 50s, with USGS gauge 01072870 reading 49°F, gauge 01073319 at 50°F and gauge 01091000 at 51°F. That is firmly in fall pattern range. Flow is modest, with gauge 01091000 at 27.4 cfs and gauge 01073319 at 12.6 cfs, so clear, low water favors careful presentations. Regionally, The Fisherman — New England Freshwater reports white perch to 1 pound 10 ounces in brackish Merrimack River sections on jigs sweetened with mummichog and on worms, with fish on bottom or suspended at mid depth. The same source notes stocked rainbow trout being taken from shore, and that anything orange, in PowerBait or hardware, is selling well to trout anglers.

What's next

Expect water temperatures to keep sliding with each cold night. With the first quarter moon, the evening and early morning hours near dusk and dawn are the windows to plan around, when bass and trout tend to feed more freely in cooling shallows.

If the cooling trend holds, trout activity should improve as surface layers drop toward the 40s, and The Fisherman — New England Freshwater notes lake trout fishing typically improves as autumn progresses. Largemouth Bass in shallow water were described as okay by the same source, so slow, compact presentations near remaining green weed edges make sense. Tactical Bassin points to jerkbaits and blade-assisted swimbaits as strong fall choices when bass are chasing baitfish, a technique worth carrying to the lake.

Low flow on the smaller gauges means fish hold tight to seams and deeper pockets. Approach quietly and downsize leaders where water runs clear. Check state regulations and stocking notices before harvesting.

Context

Mid-to-late October is typically the transition from the fall feeding spree to the pre-winter slowdown in northern New England freshwater. Water in the upper 40s to low 50s is on schedule for the date. Baitfish concentrate as weeds die back, and gamefish follow them, so structure and remaining green cover become more important than open water. Stocked trout programs often add fish in fall, which can make shore access productive for anglers without boats.
