Fall bass and perch settle in as NH waters cool
Gauge readings across the Merrimack and Lake Winnipesaukee region show water temps of 51 to 52°F this morning, with flow at 78.3 cfs on gauge 01072870, 17.4 cfs on gauge 01073319 and 34.8 cfs on gauge 01091000. Gauge 01073500 reads 117 cfs. Water in the low 50s puts freshwater fish into their fall feeding pattern, when predators key on baitfish and the bite tends to be best in the warmest part of the day. Tactical Bassin points to an October shallow bite, with jigs, soft jerkbaits and topwater working for bass that relate to subtle cover and are often overlooked. Field & Stream adds that fall bass anglers can cover water with spinnerbaits to find active fish, and that turnover rarely hits a whole lake at once, so clean, clear water is the target.

Flows are modest and temps are stable in the low 50s, so expect steady conditions over the next few days unless a front brings heavy rain. A rain-driven rise would push flow up and color the rivers, so check the gauges before you go.
Plan around the afternoon, when the sun has had time to take the edge off the water. Early mornings will be coolest and the bite may start slowly. Fishing the Midwest notes that fall fish tend to relocate to the greenest living weeds as the rest die back, a useful pattern to look for on shallow flats. Fishing the Midwest also describes a plain bottom-bouncer and nightcrawler rig that catches walleyes in cooler water.
The waxing crescent moon gives little light overnight, so dawn and dusk remain the best low-light windows.
Context
Mid-October is on schedule for the shift toward cold-water patterns in this part of New England. Weed beds are dying back, baitfish are concentrating, and fish are feeding up ahead of winter. Lakes begin to turn over around now, so expect some off-color water in shallow bays and plan to move toward cleaner water if you find it. Fishing pressure drops once boats come off the water, which can make the quieter days on the lake more productive. Check state regs before harvesting.
