426-acre lake in Berkshire County, Massachusetts. 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. Below is the species-by-species picture, pulled from the same data the map uses.
The drawn water covers 426 acres wrapped in 3.6 miles of bank. At index 1.2 the outline is almost a bowl — read the depth changes, not the shoreline. Littoral water — the productive band under ~15 ft — makes up 88% of this chart. Tip to tip the water measures near 1.4 mi with a 0.6-mi widest point. It sits in Berkshire County. If the bite dies, Ashley Lake is 6 mi to the southwest.
Early season largemouth bass use the shallows, holding in 2 to 10 ft. Summer is an 8 to 20 ft game here, winter a 6 to 20 ft one. The chart's best answer is Old creek channel — creek channel, 5 ft, prime for fall. Best bite is early morning and the evening. Tie on a texas-rigged 10" worm or a deep-diving crankbait and you're in the game.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 2 to 10 ft | dawn & dusk | Shallow bay flat (1 ft) | Spinnerbait, Chatterbait |
| Summer | 8 to 20 ft | dawn & dusk | Shallow bay flat (1 ft) | Texas-rigged 10" worm, Deep-diving crankbait |
| Fall | 4 to 15 ft | midday & dawn | Old creek channel (5 ft) | Squarebill crankbait (shad), Spinnerbait |

Spring puts yellow perch in skinny water — 3 to 12 ft is the zone. Warm water sends them out to 6 to 20 ft; cold water stacks them in 6 to 20 ft. Deep basin is the standout, a deep basin at roughly 20 ft, rated prime for fall yellow perch. Plan around early morning in the warm months. A drop-shot micro plastics or a small spoon tipped with worm covers the summer program.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 3 to 12 ft | midday & dawn | Shallow bay flat (1 ft) | Small jig + curly tail, Perch-pattern micro crank |

In spring, chain pickerel run shallow here, mostly 2 to 10 ft. Midsummer fish sit out in 3 to 15 ft before dropping to 5 to 18 ft for winter. Spring chain pickerel concentrate at Shallow bay flat, a prime-rated weed flat around 1 ft. Fish it in early morning and the evening and you'll meet the bite. You won't need more than a weedless spoon + trailer or a buzzbait most summer days.

|---|---|---|---|---|
| Spring | 2 to 10 ft | midday & dawn | Shallow bay flat (1 ft) | Inline spinner (silver), Small spoon (red/white) |

The summer box starts with a small sponge spider (fly) or a micro tube jig.
