43-acre pond near Hancock. NH GRANIT / NH Fish & Game survey water. The lake tops out around 15 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. Species by species, here's what the data says the year looks like.
On the chart, Halfmoon Pond draws 43 acres inside 1 miles of shoreline. Nearly circular (index 1.1), so the story is the bottom, not the bank. Figure 0.4 mi of water from one end to the other, 0.2 mi at the beam. You'll find it in Hillsborough County. The nearest mapped water is Horseshoe Pond, 1 mi to the east.
Spring puts largemouth bass in skinny water — 2 to 10 ft is the zone. Warm water sends them out to 5 to 15 ft; cold water stacks them in 5 to 15 ft. Shallow bay flat is the standout, a weed flat at roughly 3 ft, rated prime for spring largemouth bass. Plan around early morning and the evening in the warm months. A texas-rigged 10" worm or a deep-diving crankbait covers the summer program.
