Rating depth structure for rainbow trout.
Recent public catches load as you reach this section.
15-acre lake in Maine. The lake tops out around 18 ft. The depth chart comes from Maine Department of Inland Fisheries and Wildlife / Maine Department of Environmental Protection bathymetric survey data, so the contours are survey-derived rather than computer-modeled. Here is how the season plays out for each species, straight from the data behind the map.
The drawn water covers 15 acres wrapped in 0.7 miles of bank. Its 1.3 shoreline index means few bank features; the contours below do the pattern work. About 93% of the surface sits shallower than 15 ft — that's the weed-and-bait zone. Call it 0.3 mi long. Its nearest charted neighbour, Island Pond, is 1 mi to the northeast.
Spring rainbow trout on Upper Pond hold shallow, usually 5 to 18 ft. Depth-wise the year is flat: 5 to 18 ft in summer, 4 to 18 ft once it turns cold. Put Deep basin first on the milk run — a deep basin near 18 ft that grades good for winter. The feeding windows run early morning and the evening. The summer box starts with a dodger + spoon (deep troll) or a flutter spoon.
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 | 5 to 18 ft chart-limited; documented 5 to 20 ft | dawn & dusk | open water | Inline spinner (silver), Small spoon |
| Summer | 5 to 18 ft chart-limited; documented 8 to 30 ft | dawn & dusk | Deep basin (18 ft) | Dodger + spoon (deep troll), Flutter spoon |
| Fall | 5 to 18 ft chart-limited; documented 10 to 35 ft | dawn & dusk | Deep basin (18 ft) | Casting spoon, Jerkbait over shoals |
| Winter | 4 to 18 ft chart-limited; documented 8 to 40 ft | dawn | Deep basin (18 ft) | Jigging spoon, Tube jig (white) |
In spring, brown trout run shallow here, mostly 2 to 18 ft. Summer keeps them at 5 to 18 ft, and they winter in 3 to 18 ft. Deep basin is the standout, a deep basin at roughly 18 ft, rated good for summer brown trout. Time it for after dark and early morning. You won't need more than a spoon at the thermocline or a deep stickbait (night) most summer days.

| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 2 to 18 ft chart-limited; documented 3 to 25 ft | dawn & dusk | open water | Stickbait off planer boards (shallow), Small spoon along mud lines |
| Summer | 5 to 18 ft chart-limited; documented 25 to 60 ft | night & dawn | Deep basin (18 ft) | Spoon at the thermocline, Deep stickbait (night) |
| Fall | 3 to 18 ft chart-limited; documented 5 to 30 ft | dusk & dawn | open water | Jerkbait over gravel, Casting spoon |
| Winter | 3 to 18 ft chart-limited; documented 5 to 35 ft | dawn | Deep basin (18 ft) | Jigging spoon, Small stickbait (slow) |
Early season brook trout use the shallows, holding in 2 to 15 ft. Summer is a 5 to 18 ft game here, winter a 3 to 18 ft one. The chart's best answer is Deep basin — deep basin, 18 ft, good for summer. Best bite is early morning and the evening. Tie on a small spoon fished deep or a trolled lake-clear wobbler + worm and you're in the game.

| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 2 to 15 ft | dawn & dusk | open water | Small inline spinner (gold), Tiny spoon |
| Summer | 5 to 18 ft chart-limited; documented 10 to 30 ft | dawn & dusk | Deep basin (18 ft) | Small spoon fished deep, Trolled lake-clear wobbler + worm |
| Fall | 2 to 15 ft | midday & dawn | open water | Small spoon (orange), Spinner |
| Winter | 3 to 18 ft chart-limited; documented 3 to 20 ft | dawn | Deep basin (18 ft) | Small jigging spoon, Tungsten jig + plastic |
The spring pattern is a shallow one: yellow perch in 3 to 12 ft. As the season builds they drop to 5 to 18 ft, wintering in 5 to 18 ft. Top water on the chart: Deep basin, a deep basin in the 18 ft range, prime in fall. Time it for early morning. Summer baits: a drop-shot micro plastics or a small spoon tipped with worm gets it done.

Upper Pond is about 18 ft (5 m) deep at its deepest point. The depth chart comes from Maine Department of Inland Fisheries and Wildlife / Maine Department of Environmental Protection bathymetric survey data, so the contours are survey-derived rather than computer-modeled.
Anglers target rainbow trout, brown trout, brook trout, yellow perch on Upper Pond.
Deep basin is the top-rated area: a deep basin in about 18 ft of water that rates prime for yellow perch in fall. Scroll up to the map for the complete spot list by species and season.
For rainbow trout, the summer bite is best in early morning and the evening. Each species page section below lists the seasonal windows, and the map shows a live NOW badge when you're inside one.
