190-acre lake near Freedom. NH GRANIT / NH Fish & Game survey water. The lake tops out around 50 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.
Drawn out, this is 190 acres of water rimmed by 2.4 miles of bank. Its 1.2 shoreline index means few bank features; the contours below do the pattern work. About 38% of the surface sits shallower than 15 ft — that's the weed-and-bait zone. Tip to tip the water measures near 1 mi with a 0.4-mi widest point. You'll find it in Carroll County. The nearest mapped water is LITTLE LOON POND, 0 mi to the southwest.
The spring pattern is a shallow one: brook trout in 2 to 15 ft. As the season builds they drop to 10 to 30 ft, wintering in 3 to 20 ft. Top water on the chart: Shallow bay flat, a weed flat in the 1 ft range, good in spring. Time it for early morning and the evening. Summer baits: a small spoon fished deep or a trolled lake-clear wobbler + worm gets it done.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 2 to 15 ft | dawn & dusk | Shallow bay flat (1 ft) | Small inline spinner (gold), Tiny spoon |
| Summer | 10 to 30 ft | dawn & dusk | open water | 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 20 ft | dawn | Shallow bay flat (1 ft) | Small jigging spoon, Tungsten jig + plastic |
Start shallow in spring: rainbow trout sit in 5 to 20 ft that time of year. Summer pushes them deeper, 8 to 30 ft, and winter fish settle into 8 to 40 ft. The spot to know is Deep basin, a deep basin in about 50 ft of water that rates good for rainbow trout in winter. Warm-month bites cluster around early morning and the evening. Throw a dodger + spoon (deep troll) or a flutter spoon until the fish tell you otherwise.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 5 to 20 ft | dawn & dusk | Shallow bay flat (1 ft) | Inline spinner (silver), Small spoon |
| Summer | 8 to 30 ft | dawn & dusk | open water | Dodger + spoon (deep troll), Flutter spoon |
| Fall | 10 to 35 ft | dawn & dusk | open water | Casting spoon, Jerkbait over shoals |
| Winter | 8 to 40 ft | dawn | Deep basin (50 ft) | Jigging spoon, Tube jig (white) |
In spring, smallmouth bass run shallow here, mostly 3 to 12 ft. Midsummer fish sit out in 10 to 30 ft before dropping to 20 to 45 ft for winter. Winter smallmouth bass concentrate at Deep basin, a good-rated deep basin around 50 ft. Fish it in early morning and the evening and you'll meet the bite. You won't need more than a drop shot (goby/minnow) or a ned rig most summer days.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 3 to 12 ft | dawn & dusk | open water | Ned rig, Tube jig |
| Summer | 10 to 30 ft | dawn & dusk | open water | Drop shot (goby/minnow), Ned rig |
| Fall | 8 to 25 ft | midday & dawn | open water | Jerkbait, Blade bait |
| Winter | 20 to 45 ft | midday | Deep basin (50 ft) | Blade bait, Hair jig |
Start shallow in spring: brown bullhead sit in 2 to 8 ft that time of year. Warm water sends them out to 3 to 12 ft; cold water stacks them in 10 to 25 ft. Top water on the chart: Shallow bay flat, a weed flat in the 1 ft range, prime in spring. Fish it in after dark and the evening and you'll meet the bite.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 2 to 8 ft | dusk & night | Shallow bay flat (1 ft) | |
| Summer | 3 to 12 ft | night & dusk | Shallow bay flat (1 ft) | |
| Fall | 5 to 15 ft | dusk | open water | |
| Winter | 10 to 25 ft | midday | open water |
Spring chain pickerel on Loon Lake hold shallow, usually 2 to 10 ft. They move out to 3 to 15 ft in summer and finish the year down in 5 to 18 ft. Put Shallow bay flat first on the milk run — a weed flat near 1 ft that grades prime for spring. The feeding windows run early morning and the evening. The summer box starts with a weedless spoon + trailer or a buzzbait.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 2 to 10 ft | midday & dawn | Shallow bay flat (1 ft) | Inline spinner (silver), Small spoon (red/white) |
| Summer | 3 to 15 ft | dawn & dusk | Shallow bay flat (1 ft) | Weedless spoon + trailer, Buzzbait |
| Fall | 4 to 15 ft | midday & dawn | Shallow bay flat (1 ft) | Jerkbait along weed edges, Spinnerbait |
| Winter | 5 to 18 ft | dawn | Shallow bay flat (1 ft) | Jigging spoon (through ice) |
Start shallow in spring: landlocked salmon sit in 1 to 15 ft that time of year. Summer pushes them deeper, 15 to 50 ft, and winter fish settle into 10 to 40 ft. The spot to know is Deep basin, a deep basin in about 50 ft of water that rates prime for landlocked salmon in summer. Warm-month bites cluster around early morning and the evening. Throw a dodger + streamer down deep or a thin spoon on lead core until the fish tell you otherwise.
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 | 1 to 15 ft | dawn & dusk | open water | Streamer flies (Grey Ghost) off boards, Thin spoon (Mooselook style) |
| Summer | 15 to 50 ft chart-limited; documented 25 to 60 ft | dawn & dusk | Deep basin (50 ft) | Dodger + streamer down deep, Thin spoon on lead core |
| Fall | 5 to 30 ft | dawn & dusk | open water | Casting spoon at the mouths, Streamers |
| Winter | 10 to 40 ft | dawn | Deep basin (50 ft) | Small jigging spoon, Swedish pimple + smelt |
