The King Brook Reservoir was created in 1962 by damming the King Brook, a tributary of the Souhegan River. The reservoir covers 105 acres and has a maximum depth of 25 feet. 

Trails that skirt the shores of Heald and Castor Ponds offer views of beaver lodges. The orchard and fields offer early succession habitats for foxes, hares, and different species of warblers. You’ll also find great blue herons in the rookery to the north, plus belted kingfisher, Canada geese, wood ducks, beavers, deer, fox, squirrels, moose, and otter. Look for orchard blossoms and vernal pools in spring, mountain laurel blooming in early summer, a carpet of water lilies on King Brook Reservoir in late summer, and blooming pink bladderwort on Camp Pond in late summer.
