§ 04Field notesNew Hampshire

Where it is

Lake Winnisquam sits in Belknap County, New Hampshire, covering about 4,214 acres. Season and conditions decide the productive water; the map is the starting point.

Seasonal pattern

Spring. Warming water pulls largemouth toward shallow, protected areas where they stage and spawn; the quickest-warming pockets lead.

Summer. Heat pushes fish off the shallows toward depth and shade; work the cooler ends of the day.

Fall. As water cools, forage and bass return toward shallower water; movement is wide, so covering water pays.

Winter. Cold water settles fish deep and slow; patience and a subtle presentation are the more dependable choice.

Key structure

  • Creek and cove mouths that funnel fish and bait
  • Weed edges and the clean lines along them
  • Inside turns where a bank changes angle
  • Submerged wood, brush, and laydown cover

The calendar decides which of these is worth time on a given day.

Forage

Panfish and resident baitfish form the forage on Lake Winnisquam; bass cycle through cover as those schools shift.

Access

Boating access to Lake Winnisquam is public; check ramps, water levels, and any seasonal closures before going.

Regulations

Check current state and local regulations before fishing; limits and seasons can change.
