Fall turnover puts Winnipesaukee bass and walleye on the move

What's biting

What's next

Expect the cooling trend to keep building through the next few days, which should sharpen the bite during the low-light windows rather than change the overall pattern. Tonight's full moon adds extra low-light activity overnight and around dawn, so an early start this weekend is worth planning around.

For smallmouth working the deeper edges as water temperatures drop, Field & Stream recommends a weightless, rubber-band-rigged crayfish for a natural presentation to fish that are getting finicky as summer patterns break down. Walleye anglers can lean on the techniques Fishing the Midwest flags for the fall transition — a bottom-bouncer-and-nightcrawler plain rig or a bladed swim jig worked along shoreline flats as weeds thin out, both built to cover the same green-weed zones fish are relocating to.

Field & Stream's fall-rig guide also points to a bottom-bouncing minnow rig on a barrel swivel for big browns feeding aggressively as the water cools, a presentation worth carrying into any early-morning or evening session this week.

Context

Late September is squarely inside the classic fall-transition window for New Hampshire lake fisheries: surface cooling has begun in earnest, weed growth is starting to die back, and gamefish are shifting from open-water summer patterns toward structure and remaining green cover. Winnipesaukee's depth and volume mean that shift typically lags smaller, shallower ponds in the region, so this stretch is on schedule rather than early or late. The pattern generally strengthens through October as cooling continues, pushing more consistent low-light activity.
