264-acre pond in Plymouth County, Massachusetts. The lake tops out around 100 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 follows comes from the same scoring engine that paints the spots above.
The drawn water covers 264 acres wrapped in 2.8 miles of bank. At index 1.2 the outline is almost a bowl — read the depth changes, not the shoreline. About 13% of the surface sits shallower than 15 ft — that's the weed-and-bait zone. Call it 1.2 mi long by 0.5 mi wide at the broadest reach. Plymouth County claims this one. Its nearest charted neighbour, Long Pond (Plymouth), is 0 mi to the northwest.
Come spring, look for largemouth bass tight to the bank in 2 to 10 ft. Expect a summer slide to 8 to 20 ft, then a winter hold in 15 to 35 ft. Start at Shallow bay flat. It's a feeding flat holding about 7 ft of water and rates prime come spring. Prime time lands in early morning and the evening. A texas-rigged 10" worm or a deep-diving crankbait is the honest summer answer here.

When the water first warms, smallmouth bass slide up into 3 to 12 ft. By summer they slide out to 10 to 30 ft, and by winter most fish are in 20 to 45 ft. In summer the feeding windows fall in early morning and the evening. Keep a drop shot (goby/minnow) or a ned rig rigged through the warm months.

Keep a jig trolled/spider-rigged or a small crankbait (trolled) rigged through the warm months.
