114-acre lake near Otsego County. The lake tops out around 30 ft. The depth chart comes from published agency bathymetric survey data, so the contours are survey-derived rather than computer-modeled. The season-by-season read for each species follows, from the map's own numbers.
There are 1.8 miles of drawn shoreline to work. The shoreline is moderately structured (index 1.5) — enough points and pockets to pattern. 69% of the surface is littoral (under ~15 ft) — cover, weeds and forage water. Call it 0.7 mi long by 0.3 mi wide at the broadest reach. You'll find it in Otsego County. For a second option, Clear Lake lies 2 mi southeast.
In spring, brook trout run shallow here, mostly 2 to 15 ft. Summer pushes them deeper, 10 to 30 ft, and winter fish settle into 3 to 20 ft. Deep basin is the standout, a deep basin at roughly 30 ft, rated prime for summer brook trout. Time it for early morning and the evening. You won't need more than a small spoon fished deep or a trolled lake-clear wobbler + worm most summer days.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 2 to 15 ft | dawn & dusk | Main-lake point (3 ft) | Small inline spinner (gold), Tiny spoon |
| Summer | 10 to 30 ft | dawn & dusk | Deep basin (30 ft) | Small spoon fished deep, Trolled lake-clear wobbler + worm |
| Fall | 2 to 15 ft | midday & dawn | Main-lake point (3 ft) | Small spoon (orange), Spinner |
| Winter | 3 to 20 ft | dawn | Break off the point (10 ft) | Small jigging spoon, Tungsten jig + plastic |
Spring puts rainbow trout in skinny water — 5 to 20 ft is the zone. As the season builds they drop to 8 to 30 ft, wintering in 6 to 30 ft. Winter rainbow trout concentrate at Break off the point, a prime-rated drop-off around 10 ft. Warm-month bites cluster around early morning and the evening. A dodger + spoon (deep troll) or a flutter spoon covers the summer program.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 5 to 20 ft | dawn & dusk | Secondary point (4 ft) | Inline spinner (silver), Small spoon |
| Summer | 8 to 30 ft | dawn & dusk | Break off the point (10 ft) | Dodger + spoon (deep troll), Flutter spoon |
| Fall | 9 to 30 ft | dawn & dusk | Break off the point (10 ft) | Casting spoon, Jerkbait over shoals |
| Winter | 6 to 30 ft | dawn | Break off the point (10 ft) | Jigging spoon, Tube jig (white) |
Come spring, look for brown trout tight to the bank in 3 to 25 ft. Expect a summer slide to 9 to 30 ft, then a winter hold in 4 to 30 ft. Start at Break off the point. It's a drop-off holding about 10 ft of water and rates prime come summer. Prime time lands in after dark and early morning. A spoon at the thermocline or a deep stickbait (night) is the honest summer answer here.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 3 to 25 ft | dawn & dusk | Main-lake point (3 ft) | Stickbait off planer boards (shallow), Small spoon along mud lines |
| Summer | 9 to 30 ft | night & dawn | Break off the point (10 ft) | Spoon at the thermocline, Deep stickbait (night) |
| Fall | 5 to 30 ft | dusk & dawn | Secondary point (4 ft) | Jerkbait over gravel, Casting spoon |
| Winter | 4 to 30 ft | dawn | Break off the point (10 ft) | Jigging spoon, Small stickbait (slow) |
Come spring, look for yellow perch tight to the bank in 3 to 12 ft. They move out to 10 to 30 ft in summer and finish the year down in 9 to 30 ft. If you only fish one area, make it Back-bay flat: a weed flat around 3 ft that scores prime in spring. Best bite is early morning. A drop-shot micro plastics or a small spoon tipped with worm is the honest summer answer here.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 3 to 12 ft | midday & dawn | Back-bay flat (3 ft) | Small jig + curly tail, Perch-pattern micro crank |
| Summer | 10 to 30 ft | dawn | Deep basin (30 ft) | Drop-shot micro plastics, Small spoon tipped with worm |
| Fall | 9 to 30 ft | midday | Deep basin (30 ft) | Jigging spoon (small), Perch rig / spreader |
| Winter | 9 to 30 ft | midday & dawn | Deep basin (30 ft) | Tungsten jig + spikes, Rattle spoon (small) |
Start shallow in spring: northern pike sit in 2 to 8 ft that time of year. Warm water sends them out to 8 to 20 ft; cold water stacks them in 5 to 15 ft. Top water on the chart: Shallow bay flat, a weed flat in the 2 ft range, prime in spring. Fish it in early morning and the evening and you'll meet the bite. Throw a bucktail or a weedless spoon over cabbage until the fish tell you otherwise.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 2 to 8 ft | midday & dawn | Shallow bay flat (2 ft) | #5 inline spinner, Spoon (red/white) |
| Summer | 8 to 20 ft | dawn & dusk | Break off the point (10 ft) | Bucktail, Weedless spoon over cabbage |
| Fall | 6 to 18 ft | midday & dawn | Break off the point (10 ft) | Big rubber (Bull Dawg style), Husky-style jerkbait |
| Winter | 5 to 15 ft | midday | Back-bay flat (3 ft) | Tip-ups, Large jigging spoon |
Start shallow in spring: smallmouth bass sit in 3 to 12 ft that time of year. Warm water sends them out to 10 to 30 ft; cold water stacks them in 9 to 30 ft. Top water on the chart: Break off the point, a drop-off in the 10 ft range, prime in winter. Fish it in early morning and the evening and you'll meet the bite. Throw a drop shot (goby/minnow) or a ned rig until the fish tell you otherwise.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 3 to 12 ft | dawn & dusk | Main-lake point (3 ft) | Ned rig, Tube jig |
| Summer | 10 to 30 ft | dawn & dusk | Break off the point (10 ft) | Drop shot (goby/minnow), Ned rig |
| Fall | 8 to 25 ft | midday & dawn | Break off the point (10 ft) | Jerkbait, Blade bait |
| Winter | 9 to 30 ft | midday | Break off the point (10 ft) | Blade bait, Hair jig |

Back-bay flat is the top-rated area: a weed flat in about 3 ft of water that rates prime for yellow perch 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.
