155-acre reservoir in Essex County, Massachusetts. The lake tops out around 6 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 155 acres wrapped in 2 miles of bank. The basin is a simple one (shoreline index 1.2) — close to a bowl, so the structure on the chart matters more than the bank. Every acre of it sits shallower than ~15 ft: one big littoral zone, cover and forage throughout. The basin spans about 0.7 mi end to end and 0.6 mi across at its widest. Essex County claims this one. Its nearest charted neighbour, Lake Attitash, is 4 mi to the northwest.
Early season largemouth bass use the shallows, holding in 1 to 6 ft. Even in summer they hold at 2 to 6 ft; winter keeps them in 2 to 6 ft. Put Shallow bay flat first on the milk run — a weed flat near 1 ft that grades prime for spring. In summer the feeding windows fall in 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 | 1 to 6 ft | dawn & dusk | Shallow bay flat (1 ft) | Spinnerbait, Chatterbait |
| Summer | 2 to 6 ft | dawn & dusk | Shallow bay flat (1 ft) | Texas-rigged 10" worm, Deep-diving crankbait |
| Fall | 2 to 6 ft | midday & dawn | Old creek channel (3 ft) | Squarebill crankbait (shad), Spinnerbait |
| Winter | 2 to 6 ft | midday | Old creek channel (3 ft) | Blade bait, Jigging spoon |
Spring crappie on Upper Artichoke Reservoir hold shallow, usually 2 to 6 ft. Depth-wise the year is flat: 2 to 6 ft in summer, 2 to 6 ft once it turns cold. The chart's best answer is Old creek channel — creek channel, 3 ft, prime for fall. Prime time lands in early morning and the evening. The summer box starts with a jig trolled/spider-rigged or a small crankbait (trolled).
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 2 to 6 ft | midday & dawn | Shallow bay flat (1 ft) | 1/16 oz jig + tube, Curly-tail grub |

Shallow bay flat is the standout, a weed flat at roughly 1 ft, rated prime for spring chain pickerel. Time it for early morning and the evening. You won't need more than a weedless spoon + trailer or a buzzbait most summer days.

|---|---|---|---|---|
| Spring | 1 to 6 ft | midday & dawn | Shallow bay flat (1 ft) | Inline spinner (silver), Small spoon (red/white) |
