1,108-acre lake near T1 R5 WELS. The lake tops out around 38 ft. The depth chart comes from published agency bathymetric survey data, so the contours are survey-derived rather than computer-modeled. What the data behind the map says about each species, season by season:
Traced from the shoreline, Molunkus Lake runs 1,106 acres with 13 miles of edge. The 2.8 development index tells the story — a convoluted bank whose fishable edge far outruns the acreage. Littoral water — the productive band under ~15 ft — makes up 51% of this chart. Call it 4 mi long by 1.4 mi wide at the broadest reach. The water lies in Aroostook County. The nearest mapped water is Salmon Stream Lake, 9 mi to the northwest.
Spring puts brook trout in skinny water — 2 to 15 ft is the zone. Warm water sends them out to 10 to 30 ft; cold water stacks them in 3 to 20 ft. Break off the point is the standout, a drop-off at roughly 19 ft, rated prime for summer brook trout. Plan around early morning and the evening in the warm months. A small spoon fished deep or a trolled lake-clear wobbler + worm covers the summer program.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 2 to 15 ft | dawn & dusk | Main-lake point (8 ft) | Small inline spinner (gold), Tiny spoon |
| Summer | 10 to 30 ft | dawn & dusk | Break off the point (19 ft) | Small spoon fished deep, Trolled lake-clear wobbler + worm |
| Fall | 2 to 15 ft | midday & dawn | Main-lake point (8 ft) | Small spoon (orange), Spinner |
| Winter | 3 to 20 ft | dawn | Break off the point (19 ft) | Small jigging spoon, Tungsten jig + plastic |
In spring, landlocked salmon run shallow here, mostly 1 to 15 ft. Midsummer fish sit out in 11 to 38 ft before dropping to 10 to 38 ft for winter. Summer landlocked salmon concentrate at Deep basin, a prime-rated deep basin around 36 ft. Fish it in early morning and the evening and you'll meet the bite. You won't need more than a dodger + streamer down deep or a thin spoon on lead core most summer days.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 1 to 15 ft | dawn & dusk | Main-lake point (8 ft) | Streamer flies (Grey Ghost) off boards, Thin spoon (Mooselook style) |
| Summer | 11 to 38 ft | dawn & dusk | Deep basin (36 ft) | Dodger + streamer down deep, Thin spoon on lead core |
| Fall | 5 to 30 ft | dawn & dusk | Main-lake point (8 ft) | Casting spoon at the mouths, Streamers |
| Winter | 10 to 38 ft | dawn | Deep basin (36 ft) | Small jigging spoon, Swedish pimple + smelt |
The spring pattern is a shallow one: smallmouth bass in 3 to 12 ft. As the season builds they drop to 10 to 30 ft, wintering in 11 to 38 ft. Top water on the chart: Main-lake point, a point in the 8 ft range, prime in fall. Time it for early morning and the evening. Summer baits: a drop shot (goby/minnow) or a ned rig gets it done.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 3 to 12 ft | dawn & dusk | Main-lake point (8 ft) | Ned rig, Tube jig |
| Summer | 10 to 30 ft | dawn & dusk | Break off the point (19 ft) | Drop shot (goby/minnow), Ned rig |
| Fall | 8 to 25 ft | midday & dawn | Main-lake point (8 ft) | Jerkbait, Blade bait |
| Winter | 11 to 38 ft | midday | Break off the point (19 ft) | Blade bait, Hair jig |
