20-acre pond in Middlesex County, Massachusetts. The lake tops out around 15 ft. The depth chart comes from published agency bathymetric survey data, so the contours are survey-derived rather than computer-modeled. Species by species, here's what the data says the year looks like.
On the chart, Wedge Pond draws 20 acres inside 0.7 miles of shoreline. The basin is a simple one (shoreline index 1.1) — close to a bowl, so the structure on the chart matters more than the bank. End to end it runs roughly 0.3 mi, about 0.2 mi across. The water lies in Middlesex County. Closest neighbour on DepthScout: Upper Mystic Lake, 1 mi south of here.
In spring, largemouth bass run shallow here, mostly 2 to 10 ft. Summer pushes them deeper, 5 to 15 ft, and winter fish settle into 5 to 15 ft. Shallow bay flat is the standout, a weed flat at roughly 3 ft, rated prime for spring largemouth bass. Time it for early morning and the evening. You won't need more than a texas-rigged 10" worm or a deep-diving crankbait most summer days.
Depth note: when a documented seasonal range extends below this chart, the table shows the deepest mapped working water, not a verified holding depth.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 2 to 10 ft | dawn & dusk | Shallow bay flat (3 ft) | Spinnerbait, Chatterbait |
| Summer | 5 to 15 ft chart-limited; documented 8 to 20 ft | dawn & dusk | Break off the point (15 ft) | Texas-rigged 10" worm, Deep-diving crankbait |
| Fall | 4 to 15 ft | midday & dawn | Main-lake point (4 ft) | Squarebill crankbait (shad), Spinnerbait |
| Winter | 5 to 15 ft chart-limited; documented 15 to 35 ft | midday | Break off the point (15 ft) | Blade bait, Jigging spoon |
Spring yellow perch on Wedge Pond hold shallow, usually 3 to 12 ft. By summer they slide out to 5 to 15 ft, and by winter most fish are in 5 to 15 ft. The chart's best answer is Shallow bay flat — weed flat, 3 ft, prime for spring. Prime time lands in early morning. The summer box starts with a drop-shot micro plastics or a small spoon tipped with worm.

| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 3 to 12 ft | midday & dawn | Shallow bay flat (3 ft) | Small jig + curly tail, Perch-pattern micro crank |
| Summer | 5 to 15 ft chart-limited; documented 10 to 30 ft | dawn | Deep basin (15 ft) | Drop-shot micro plastics, Small spoon tipped with worm |
| Fall | 5 to 15 ft chart-limited; documented 12 to 35 ft | midday | Deep basin (15 ft) | Jigging spoon (small), Perch rig / spreader |
| Winter | 5 to 15 ft chart-limited; documented 15 to 35 ft | midday & dawn | Deep basin (15 ft) | Tungsten jig + spikes, Rattle spoon (small) |
Early season chain pickerel use the shallows, holding in 2 to 10 ft. Expect a summer slide to 3 to 15 ft, then a winter hold in 4 to 15 ft. Put Shallow bay flat first on the milk run — a weed flat near 3 ft that grades prime for spring. In summer the feeding windows fall in early morning and the evening. Tie on a weedless spoon + trailer or a buzzbait and you're in the game.

The spring pattern is a shallow one: bluegill in 1 to 6 ft. As the season builds they drop to 4 to 15 ft, wintering in 5 to 15 ft. Top water on the chart: Shallow bay flat, a weed flat in the 3 ft range, prime in spring. Time it for early morning and the evening. Summer baits: a small sponge spider (fly) or a micro tube jig gets it done.
