Rating depth structure for brook trout.

649-acre lake near Hopkins Academy Grant Township. The lake tops out around 22 ft. The depth chart comes from Maine Department of Environmental Protection bathymetric survey data, so the contours are survey-derived rather than computer-modeled. The rest of this page walks each species through its year, using the map's own scoring.
The drawn water covers 648 acres wrapped in 7.4 miles of bank, with 2 islands in the mix. With a 2.1 development index there's bank structure worth casting at, in moderation. Littoral water — the productive band under ~15 ft — makes up 77% of this chart. Call it 2.9 mi long by 0.7 mi wide at the broadest reach. It sits in Penobscot County. Cedar Lake sits 5 mi southwest — the closest neighbouring chart.
Spring brook trout on Nollesemic Lake hold shallow, usually 2 to 15 ft. By summer they slide out to 7 to 22 ft, and by winter most fish are in 3 to 20 ft. The chart's best answer is Deep basin — deep basin, 21 ft, prime for summer. Prime time lands in early morning and the evening. The summer box starts with a small spoon fished deep or a trolled lake-clear wobbler + worm.
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 15 ft | dawn & dusk | Main-lake point (2 ft) | Small inline spinner (gold), Tiny spoon |
| Summer | 7 to 22 ft chart-limited; documented 10 to 30 ft | dawn & dusk | Deep basin (21 ft) | Small spoon fished deep, Trolled lake-clear wobbler + worm |
| Fall | 2 to 15 ft | midday & dawn | Main-lake point (2 ft) | Small spoon (orange), Spinner |
| Winter | 3 to 20 ft | dawn | Deep basin (21 ft) | Small jigging spoon, Tungsten jig + plastic |
When the water first warms, brown bullhead slide up into 2 to 8 ft. By summer they slide out to 3 to 12 ft, and by winter most fish are in 7 to 22 ft. If you only fish one area, make it Deep basin: a deep basin around 21 ft that scores prime in winter. In summer the feeding windows fall in after dark and the evening.

| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 2 to 8 ft | dusk & night | Shallow bay flat (2 ft) | |
| Summer | 3 to 12 ft | night & dusk | Back-bay flat (3 ft) | |
| Fall | 5 to 15 ft | dusk | Back-bay flat (3 ft) | |
| Winter | 7 to 22 ft chart-limited; documented 10 to 25 ft | midday | Deep basin (21 ft) |
The spring pattern is a shallow one: pumpkinseed in 1 to 8 ft. As the season builds they drop to 2 to 10 ft, wintering in 6 to 18 ft. Top water on the chart: Shallow bay flat, a weed flat in the 2 ft range, prime in spring. Time it for the evening and early morning. Summer baits: a micro tube or a sponge spider (fly) gets it done.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 1 to 8 ft | midday & dusk | Shallow bay flat (2 ft) | Micro jig under a float, Tiny beetle-spin |
| Summer | 2 to 10 ft | dusk & dawn | Shallow bay flat (2 ft) | Micro tube, Sponge spider (fly) |
| Fall | 4 to 14 ft | dusk & dawn | Back-bay flat (3 ft) | Micro jig + waxworm, Small spoon tipped |
| Winter | 6 to 18 ft | dawn | Back-bay flat (3 ft) | Tungsten ice jig + plastic, Tiny spoon |
Start shallow in spring: yellow perch sit in 3 to 12 ft that time of year. Warm water sends them out to 7 to 22 ft; cold water stacks them in 7 to 22 ft. Top water on the chart: Back-bay flat, a weed flat in the 3 ft range, prime in spring. Fish it in early morning and you'll meet the bite. Throw a drop-shot micro plastics or a small spoon tipped with worm until the fish tell you otherwise.

| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 3 to 12 ft | midday & dawn | Back-bay flat (3 ft) | Small jig + curly tail, Perch-pattern micro crank |
| Summer | 7 to 22 ft chart-limited; documented 10 to 30 ft | dawn | Deep basin (21 ft) | Drop-shot micro plastics, Small spoon tipped with worm |
| Fall | 7 to 22 ft chart-limited; documented 12 to 35 ft | midday | Deep basin (21 ft) | Jigging spoon (small), Perch rig / spreader |
| Winter | 7 to 22 ft chart-limited; documented 15 to 35 ft | midday & dawn | Deep basin (21 ft) | Tungsten jig + spikes, Rattle spoon (small) |
Spring white perch on Nollesemic Lake hold shallow, usually 4 to 15 ft. By summer they slide out to 7 to 22 ft, and by winter most fish are in 7 to 22 ft. The chart's best answer is Deep basin — deep basin, 21 ft, prime for summer. Prime time lands in early morning. The summer box starts with a small spinner rig drifted or a 1/8 oz jigging spoon.

| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 4 to 15 ft | dusk | Back-bay flat (3 ft) | Small jig + curly tail, Inline spinner (silver) |
| Summer | 7 to 22 ft chart-limited; documented 15 to 40 ft | dawn | Deep basin (21 ft) | Small spinner rig drifted, 1/8 oz jigging spoon |
| Fall | 7 to 22 ft chart-limited; documented 15 to 45 ft | midday | Deep basin (21 ft) | Jigging spoon (small), Blade bait |
| Winter | 7 to 22 ft chart-limited; documented 20 to 50 ft | dusk | Deep basin (21 ft) | Small rattle spoon, Tungsten + spikes |
The spring pattern is a shallow one: chain pickerel in 2 to 10 ft. Midsummer fish sit out in 3 to 15 ft before dropping to 5 to 18 ft for winter. The spot to know is Shallow bay flat, a weed flat in about 2 ft of water that rates prime for chain pickerel in spring. Plan around early morning and the evening in the warm months. Summer baits: a weedless spoon + trailer or a buzzbait gets it done.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 2 to 10 ft | midday & dawn | Shallow bay flat (2 ft) | Inline spinner (silver), Small spoon (red/white) |
| Summer | 3 to 15 ft | dawn & dusk | Back-bay flat (3 ft) | Weedless spoon + trailer, Buzzbait |
| Fall | 4 to 15 ft | midday & dawn | Back-bay flat (3 ft) | Jerkbait along weed edges, Spinnerbait |
| Winter | 5 to 18 ft | dawn | Back-bay flat (3 ft) | Jigging spoon (through ice) |
