Rating depth structure for largemouth bass.
Recent public catches load as you reach this section.
257-acre pond in Barnstable County, Massachusetts. The lake tops out around 30 ft. The depth chart comes from published agency bathymetric survey data, so the contours are survey-derived rather than computer-modeled. Here's the year, species by species, as the scoring engine sees it.
On the chart, Upper Millpond draws 257 acres inside 2.7 miles of shoreline. A shoreline index of 1.2 says round and simple: fish relate to depth changes here, not shoreline features. Roughly 37% of the water is 15 ft or less, the band where the food chain lives. Call it 1.1 mi long by 0.5 mi wide at the broadest reach. You'll find it in Barnstable County. Closest neighbour on DepthScout: Walkers Pond, 1 mi southwest of here.
These fish are listed in an exact-water agency record as forage or ecological context. They are not target-species profiles and do not affect DepthScout's Prime, Good, or Fair spot ratings.

The spring pattern is a shallow one: largemouth bass in 2 to 10 ft. Midsummer fish sit out in 8 to 20 ft before dropping to 9 to 30 ft for winter. The spot to know is Shallow bay flat, a weed flat in about 1 ft of water that rates prime for largemouth bass in spring. Plan around early morning and the evening in the warm months. Summer baits: a texas-rigged 10" worm or a deep-diving crankbait gets it done.
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 (1 ft) | Spinnerbait, Chatterbait |
| Summer | 8 to 20 ft | dawn & dusk | Shallow feeding flat (20 ft) | Texas-rigged 10" worm, Deep-diving crankbait |
| Fall | 4 to 15 ft | midday & dawn | Shallow bay flat (1 ft) | Squarebill crankbait (shad), Spinnerbait |
| Winter | 9 to 30 ft chart-limited; documented 15 to 35 ft | midday | Deep basin (30 ft) | Blade bait, Jigging spoon |
Start shallow in spring: smallmouth bass sit in 3 to 12 ft that time of year. Warm water sends them out to 10 to 30 ft; cold water stacks them in 9 to 30 ft. Top water on the chart: Deep basin, a deep basin in the 30 ft range, good in winter. Fish it in early morning and the evening and you'll meet the bite. Throw a drop shot (goby/minnow) or a ned rig until the fish tell you otherwise.

| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 3 to 12 ft | dawn & dusk | open water | Ned rig, Tube jig |
| Summer | 10 to 30 ft | dawn & dusk | open water | Drop shot (goby/minnow), Ned rig |
| Fall | 8 to 25 ft | midday & dawn | open water | Jerkbait, Blade bait |
| Winter | 9 to 30 ft chart-limited; documented 20 to 45 ft | midday | Deep basin (30 ft) | Blade bait, Hair jig |
Come spring, look for yellow perch tight to the bank in 3 to 12 ft. They move out to 10 to 30 ft in summer and finish the year down in 9 to 30 ft. If you only fish one area, make it Deep basin: a deep basin around 30 ft that scores prime in fall. Best bite is early morning. A drop-shot micro plastics or a small spoon tipped with worm is the honest summer answer here.

| 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 |
| Summer | 10 to 30 ft | dawn | Deep basin (30 ft) | Drop-shot micro plastics, Small spoon tipped with worm |
| Fall | 9 to 30 ft chart-limited; documented 12 to 35 ft | midday | Deep basin (30 ft) | Jigging spoon (small), Perch rig / spreader |
| Winter | 9 to 30 ft chart-limited; documented 15 to 35 ft | midday & dawn | Deep basin (30 ft) | Tungsten jig + spikes, Rattle spoon (small) |
When the water first warms, chain pickerel slide up into 2 to 10 ft. Summer is a 3 to 15 ft game here, winter a 5 to 18 ft one. Start at Shallow bay flat. It's a weed flat holding about 1 ft of water and rates prime come spring. The feeding windows run early morning and the evening. Keep a weedless spoon + trailer or a buzzbait rigged through the warm months.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 2 to 10 ft | midday & dawn | Shallow bay flat (1 ft) | Inline spinner (silver), Small spoon (red/white) |
| Summer | 3 to 15 ft | dawn & dusk | Shallow bay flat (1 ft) | Weedless spoon + trailer, Buzzbait |
| Fall | 4 to 15 ft | midday & dawn | Shallow bay flat (1 ft) | Jerkbait along weed edges, Spinnerbait |
| Winter | 5 to 18 ft | dawn | Shallow feeding flat (20 ft) | Jigging spoon (through ice) |
In spring, white perch run shallow here, mostly 4 to 15 ft. Summer pushes them deeper, 9 to 30 ft, and winter fish settle into 9 to 30 ft. Deep basin is the standout, a deep basin at roughly 30 ft, rated prime for summer white perch. Time it for early morning. You won't need more than a small spinner rig drifted or a 1/8 oz jigging spoon most summer days.

| Winter | 9 to 30 ft chart-limited; documented 20 to 50 ft | dusk | Deep basin (30 ft) | Small rattle spoon, Tungsten + spikes |
Early season pumpkinseed use the shallows, holding in 1 to 8 ft. Summer is a 2 to 10 ft game here, winter a 6 to 18 ft one. The chart's best answer is Shallow bay flat — weed flat, 1 ft, prime for spring. Best bite is the evening and early morning. Tie on a micro tube or a sponge spider (fly) and you're in the game.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 1 to 8 ft | midday & dusk | Shallow bay flat (1 ft) | Micro jig under a float, Tiny beetle-spin |
| Summer | 2 to 10 ft | dusk & dawn | Shallow bay flat (1 ft) | Micro tube, Sponge spider (fly) |
| Fall | 4 to 14 ft | dusk & dawn | Shallow bay flat (1 ft) | Micro jig + waxworm, Small spoon tipped |
| Winter | 6 to 18 ft | dawn | Shallow feeding flat (20 ft) | Tungsten ice jig + plastic, Tiny spoon |
