103-acre lake in Worcester County, Massachusetts. The lake tops out around 40 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.
Traced from the shoreline, Lake Whalom runs 103 acres with 1.6 miles of edge. At index 1.1 the outline is almost a bowl — read the depth changes, not the shoreline. About 39% of the surface sits shallower than 15 ft — that's the weed-and-bait zone. Figure 0.6 mi of water from one end to the other, 0.4 mi at the beam. You'll find it in Worcester County. The nearest mapped water is Fort Pond, 4 mi to the southeast.
In spring, largemouth bass run shallow here, mostly 2 to 10 ft. Midsummer fish sit out in 8 to 20 ft before dropping to 15 to 35 ft for winter. Spring largemouth bass concentrate at Shallow bay flat, a prime-rated weed flat around 3 ft. Fish it in early morning and the evening and you'll meet the bite. You won't need more than a texas-rigged 10" worm or a deep-diving crankbait most summer days.

A drop shot (goby/minnow) or a ned rig covers the summer program.
