2,568-acre lake near T13 R8 WELS. The lake tops out around 46 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.
The outline encloses 2,562 acres, worked by 12.6 miles of shoreline, broken up by 7 islands. A middling shoreline index (1.8) gives it some bays to work without being a maze. The shallow band under 15 ft claims about 56% of the surface — that's where the groceries are. Tip to tip the water measures near 4 mi with a 1.9-mi widest point. Aroostook County claims this one. Its nearest charted neighbour, Round Pond, is 2 mi to the northeast.
Come spring, look for brook trout tight to the bank in 2 to 15 ft. They move out to 10 to 30 ft in summer and finish the year down in 3 to 20 ft. If you only fish one area, make it Chase Brook inflow: an inflow / creek mouth around 11 ft that scores prime in spring. Best bite is early morning and the evening. A small spoon fished deep or a trolled lake-clear wobbler + worm is the honest summer answer here.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 2 to 15 ft | dawn & dusk | Chase Brook inflow (11 ft) | Small inline spinner (gold), Tiny spoon |
| Summer | 10 to 30 ft | dawn & dusk | Chase Brook inflow (11 ft) | Small spoon fished deep, Trolled lake-clear wobbler + worm |
| Fall | 2 to 15 ft | midday & dawn | Chase Brook inflow (11 ft) | Small spoon (orange), Spinner |
| Winter | 3 to 20 ft | dawn | Chase Brook inflow (11 ft) | Small jigging spoon, Tungsten jig + plastic |
Spring burbot on Fish River Lake hold shallow, usually 14 to 46 ft. Depth-wise the year is flat: 14 to 46 ft in summer, 12 to 46 ft once it turns cold. Put Deep basin first on the milk run — a deep basin near 46 ft that grades prime for spring. The feeding windows run after dark and midday. The summer box starts with a heavy jig + cut bait.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 14 to 46 ft | night & dusk | Deep basin (46 ft) | Glow jigging spoon + cut bait, Rattle bait (dark) |
| Summer | 14 to 46 ft | night & midday | Deep basin (46 ft) | Heavy jig + cut bait |
| Fall | 14 to 46 ft | night & dusk | Deep basin (46 ft) | Glow spoon + minnow head, Blade bait (slow) |
| Winter | 12 to 46 ft | night & dusk | Deep basin (46 ft) | Glow tungsten + cut bait, Rattle spoon + minnow head |
When the water first warms, landlocked salmon slide up into 1 to 15 ft. Summer is a 14 to 46 ft game here, winter a 10 to 40 ft one. Start at Chase Brook inflow. It's an inflow / creek mouth holding about 11 ft of water and rates prime come spring. The feeding windows run early morning and the evening. Keep a dodger + streamer down deep or a thin spoon on lead core rigged through the warm months.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 1 to 15 ft | dawn & dusk | Chase Brook inflow (11 ft) | Streamer flies (Grey Ghost) off boards, Thin spoon (Mooselook style) |
| Summer | 14 to 46 ft | dawn & dusk | Deep basin (46 ft) | Dodger + streamer down deep, Thin spoon on lead core |
| Fall | 5 to 30 ft | dawn & dusk | Chase Brook inflow (11 ft) | Casting spoon at the mouths, Streamers |
| Winter | 10 to 40 ft | dawn | Break off the point (14 ft) | Small jigging spoon, Swedish pimple + smelt |
Early season brown bullhead use the shallows, holding in 2 to 8 ft. Summer is a 3 to 12 ft game here, winter a 10 to 25 ft one. The chart's best answer is Shallow bay flat — weed flat, 7 ft, prime for spring. Best bite is after dark and the evening.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 2 to 8 ft | dusk & night | Shallow bay flat (7 ft) | |
| Summer | 3 to 12 ft | night & dusk | Shallow bay flat (7 ft) | |
| Fall | 5 to 15 ft | dusk | Old creek channel (14 ft) | |
| Winter | 10 to 25 ft | midday | Old creek channel (14 ft) |
Spring lake trout on Fish River Lake hold shallow, usually 10 to 40 ft. They move out to 14 to 46 ft in summer and finish the year down in 12 to 46 ft. Put Deep basin first on the milk run — a deep basin near 46 ft that grades prime for summer. The feeding windows run early morning. The summer box starts with a white tube jig (deep) or a magnum spoon on downrigger.
| 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 | 14 to 46 ft | dawn | Deep basin (46 ft) | White tube jig (deep), Magnum spoon on downrigger |
| Fall | 9 to 46 ft | dusk & dawn | Secondary point (6 ft) | Heavy casting spoon, Jigging rap over reefs |
| Winter | 12 to 46 ft | dawn | Deep basin (46 ft) | White tube jig, Airplane jig |
