5-acre lake near Cumbria. The lake tops out around 30 ft. These contours are modeled — built from the real shoreline and the water's maximum depth — so read them as a guide, never as navigation. Here's the year, species by species, as the scoring engine sees it.
The drawn water covers 5 acres wrapped in 0.4 miles of bank. Nearly circular (index 1.3), so the story is the bottom, not the bank. 50% of the surface is littoral (under ~15 ft), per the model — cover, weeds and forage water.
Start shallow in spring: brown trout sit in 3 to 25 ft that time of year. Warm water sends them out to 9 to 30 ft; cold water stacks them in 4 to 30 ft. Top water on the chart: Shoreline break, a drop-off in the 14-ft range, prime in summer. Fish it in after dark and early morning and you'll meet the bite. Throw a spoon at the thermocline or a deep stickbait (night) until the fish tell you otherwise.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 3 to 25 ft | dawn & dusk | Shoreline break (14 ft) | Stickbait off planer boards (shallow), Small spoon along mud lines |
| Summer | 9 to 30 ft | night & dawn | Shoreline break (14 ft) | Spoon at the thermocline, Deep stickbait (night) |
| Fall | 5 to 30 ft | dusk & dawn | Shoreline break (14 ft) | Jerkbait over gravel, Casting spoon |
| Winter | 4 to 30 ft | dawn | Shoreline break (14 ft) | Jigging spoon, Small stickbait (slow) |
When the water first warms, european perch slide up into 3 to 12 ft. Summer is a 8 to 28 ft game here, winter a 9 to 30 ft one. Start at Shallow bay flat. It's a weed flat holding about 4 ft of water and rates prime come spring. The feeding windows run early morning. Keep a drop-shot micro plastics or a small crankbait (perch pattern) rigged through the warm months.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 3 to 12 ft | midday & dawn | Shallow bay flat (4 ft) | Small jig + curly tail, Inline spinner #1-2 |

Spring northern pike on Greendale Tarn hold shallow, usually 2 to 8 ft. They move out to 8 to 20 ft in summer and finish the year down in 5 to 15 ft. Put Shallow bay flat first on the milk run — a weed flat near 4 ft that grades prime for spring. The feeding windows run early morning and the evening. The summer box starts with a bucktail or a weedless spoon over cabbage.

Spring puts arctic char in skinny water — 4 to 15 ft is the zone. As the season builds they drop to 9 to 30 ft, wintering in 8 to 30 ft. Summer arctic char concentrate at Deep basin, a prime-rated deep basin around 26 ft. Warm-month bites cluster around early morning. A jigging spoon vertical or a tube jig (smelt) covers the summer program.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 4 to 15 ft | midday & dawn | Shoreline break (14 ft) | Small casting spoon (silver/orange), Jerkbait (small) |
