917-acre lake near T9 R11 WELS. The lake tops out around 59 ft. The depth chart comes from published agency 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 914 acres wrapped in 9.5 miles of bank, broken up by 7 islands. A development index of 2.3 means a maze of bays and points: far more casting targets than a round bowl of the same size. 88% of the surface is littoral (under ~15 ft) — cover, weeds and forage water. Tip to tip the water measures near 2.2 mi with a 1.3-mi widest point. It sits in Piscataquis County. If the bite dies, Leadbetter Pond is 2 mi to the southeast.
Early season brook trout use the shallows, holding in 2 to 15 ft. Expect a summer slide to 10 to 30 ft, then a winter hold in 3 to 20 ft. Put Creek inflow first on the milk run — an inflow / creek mouth near 2 ft that grades prime for spring. In summer the feeding windows fall in 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 | Creek inflow (2 ft) | Small inline spinner (gold), Tiny spoon |
| Summer | 10 to 30 ft | dawn & dusk | Deep basin (29 ft) | Small spoon fished deep, Trolled lake-clear wobbler + worm |
| Fall | 2 to 15 ft | midday & dawn | Creek inflow (2 ft) | Small spoon (orange), Spinner |
| Winter | 3 to 20 ft | dawn | Creek inflow (2 ft) | Small jigging spoon, Tungsten jig + plastic |
When the water first warms, burbot slide up into 18 to 59 ft. There's no big seasonal slide here — summer means 18 to 59 ft, winter 15 to 59 ft. If you only fish one area, make it Deep basin: a deep basin around 29 ft that scores prime in spring. In summer the feeding windows fall in after dark and midday. Keep a heavy jig + cut bait rigged through the warm months.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 18 to 59 ft | night & dusk | Deep basin (29 ft) | Glow jigging spoon + cut bait, Rattle bait (dark) |
| Summer | 18 to 59 ft | night & midday | Deep basin (29 ft) | Heavy jig + cut bait |
| Fall | 18 to 59 ft | night & dusk | Deep basin (29 ft) | Glow spoon + minnow head, Blade bait (slow) |
| Winter | 15 to 59 ft | night & dusk | Deep basin (29 ft) | Glow tungsten + cut bait, Rattle spoon + minnow head |
When the water first warms, lake trout slide up into 10 to 40 ft. By summer they slide out to 18 to 59 ft, and by winter most fish are in 15 to 59 ft. If you only fish one area, make it Deep basin: a deep basin around 29 ft that scores prime in summer. In summer the feeding windows fall in early morning. Keep a white tube jig (deep) or a magnum spoon on downrigger rigged through the warm months.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 10 to 40 ft | dawn & dusk | Break off the point (14 ft) | Casting spoon over shoals, Jerkbait (shallow) |
| Summer | 18 to 59 ft | dawn | Deep basin (29 ft) | White tube jig (deep), Magnum spoon on downrigger |
| Fall | 10 to 50 ft | dusk & dawn | Break off the point (14 ft) | Heavy casting spoon, Jigging rap over reefs |
| Winter | 15 to 59 ft | dawn | Deep basin (29 ft) | White tube jig, Airplane jig |
Come spring, look for brown bullhead tight to the bank in 2 to 8 ft. Expect a summer slide to 3 to 12 ft, then a winter hold in 10 to 25 ft. Start at Shallow bay flat. It's a weed flat holding about 2 ft of water and rates prime come spring. Prime time lands 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 | Shallow bay flat (2 ft) | |
| Fall | 5 to 15 ft | dusk | Shallow bay flat (2 ft) | |
| Winter | 10 to 25 ft | midday | Deep basin (29 ft) |

Anglers target brook trout, burbot, lake trout, brown bullhead on Spider Lake.
Creek inflow is the top-rated area: an inflow / creek mouth in about 2 ft of water that rates prime for brook trout in spring. Every other rated spot, per species and season, is on the map above.
For brook 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.
