83-acre pond near Pelham. NH GRANIT / NH Fish & Game survey water. The lake tops out around 20 ft. The depth chart is built from real state fisheries GPS surveys, so the humps, channels and drop-offs you see are measured, not guessed. What the data behind the map says about each species, season by season:
The drawn water covers 83 acres wrapped in 1.6 miles of bank. A shoreline index of 1.3 says round and simple: fish relate to depth changes here, not shoreline features. Littoral water — the productive band under ~15 ft — makes up 85% of this chart. End to end it runs roughly 0.7 mi, about 0.3 mi across. Hillsborough County claims this one. If the bite dies, Long Pond is 2 mi to the south.

The summer box starts with a texas-rigged 10" worm or a deep-diving crankbait.
