4,800-acre reservoir near Deposit. The lake tops out around 144 ft. The depth chart comes from U.S. Geological Survey 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 4,499 acres, worked by 48.3 miles of shoreline. An index of 5.1 puts the bank firmly in maze territory: point after pocket after cove, every one a casting target. Littoral water — the productive band under ~15 ft — makes up 12% of this chart. End to end it runs roughly 10.6 mi, about 6.1 mi across. It sits in Delaware County. Arctic Lake sits 9 mi northwest — the closest neighbouring chart.
When the water first warms, rainbow trout slide up into 5 to 20 ft. By summer they slide out to 8 to 30 ft, and by winter most fish are in 8 to 40 ft. If you only fish one area, make it Rock reef: a rock pile around 10 ft that scores prime in fall. In summer the feeding windows fall in early morning and the evening. Keep a dodger + spoon (deep troll) or a flutter spoon rigged through the warm months.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 5 to 20 ft | dawn & dusk | Main-lake point (18 ft) | Inline spinner (silver), Small spoon |
| Summer | 8 to 30 ft | dawn & dusk | Rock reef (10 ft) | Dodger + spoon (deep troll), Flutter spoon |
| Fall | 10 to 35 ft | dawn & dusk | Rock reef (10 ft) | Casting spoon, Jerkbait over shoals |
| Winter | 8 to 40 ft | dawn | Sharp break (17 ft) | Jigging spoon, Tube jig (white) |
Early season smallmouth bass use the shallows, holding in 3 to 12 ft. Summer is a 10 to 30 ft game here, winter a 20 to 45 ft one. The chart's best answer is Rock reef — rock pile, 10 ft, prime for spring. Best bite is early morning and the evening. Tie on a drop shot (goby/minnow) or a ned rig and you're in the game.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 3 to 12 ft | dawn & dusk | Rock reef (10 ft) | Ned rig, Tube jig |
| Summer | 10 to 30 ft | dawn & dusk | Rock reef (10 ft) | Drop shot (goby/minnow), Ned rig |
| Fall | 8 to 25 ft | midday & dawn | Main-lake point (18 ft) | Jerkbait, Blade bait |
| Winter | 20 to 45 ft | midday | Sharp break (17 ft) | Blade bait, Hair jig |
In spring, yellow perch run shallow here, mostly 3 to 12 ft. Midsummer fish sit out in 10 to 30 ft before dropping to 15 to 35 ft for winter. Summer yellow perch concentrate at Sharp break, a prime-rated drop-off around 17 ft. Fish it in early morning and you'll meet the bite. You won't need more than a drop-shot micro plastics or a small spoon tipped with worm most summer days.
| 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 | Sharp break (17 ft) | Drop-shot micro plastics, Small spoon tipped with worm |
| Fall | 12 to 35 ft | midday | Sharp break (17 ft) | Jigging spoon (small), Perch rig / spreader |
| Winter | 15 to 35 ft | midday & dawn | Offshore hump (15 ft) | Tungsten jig + spikes, Rattle spoon (small) |
Early season crappie use the shallows, holding in 2 to 8 ft. Summer is a 10 to 25 ft game here, winter a 15 to 35 ft one. The chart's best answer is Back-bay flat — feeding flat, 3 ft, prime for spring. Best bite is early morning and the evening. Tie on a jig trolled/spider-rigged or a small crankbait (trolled) and you're in the game.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 2 to 8 ft | midday & dawn | Back-bay flat (3 ft) | 1/16 oz jig + tube, Curly-tail grub |
| Summer | 10 to 25 ft | dawn & dusk | Offshore hump (15 ft) | Jig trolled/spider-rigged, Small crankbait (trolled) |
| Fall | 8 to 20 ft | dawn | Sharp break (17 ft) | Jig + minnow combo, Small swimbait (1.5-2") |
| Winter | 15 to 35 ft | midday | Offshore hump (15 ft) | Tungsten jig + soft plastic, Tiny jigging spoon |
When the water first warms, common carp slide up into 2 to 10 ft. By summer they slide out to 3 to 15 ft, and by winter most fish are in 10 to 30 ft. If you only fish one area, make it Back-bay flat: a feeding flat around 3 ft that scores prime in spring. In summer the feeding windows fall in early morning and the evening.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 2 to 10 ft | midday & dawn | Back-bay flat (3 ft) | |
| Summer | 3 to 15 ft | dawn & dusk | Back-bay flat (3 ft) | |
| Fall | 5 to 18 ft | midday | Feeding flat (15 ft) | |
| Winter | 10 to 30 ft | midday | open water |
The spring pattern is a shallow one: brown trout in 3 to 25 ft. Midsummer fish sit out in 25 to 60 ft before dropping to 5 to 35 ft for winter. The spot to know is Sharp break, a drop-off in about 62 ft of water that rates prime for brown trout in summer. Plan around after dark and early morning in the warm months. Summer baits: a spoon at the thermocline or a deep stickbait (night) gets it done.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 3 to 25 ft | dawn & dusk | Main-lake point (18 ft) | Stickbait off planer boards (shallow), Small spoon along mud lines |
| Summer | 25 to 60 ft | night & dawn | Sharp break (62 ft) | Spoon at the thermocline, Deep stickbait (night) |
| Fall | 5 to 30 ft | dusk & dawn | Rock reef (10 ft) | Jerkbait over gravel, Casting spoon |
| Winter | 5 to 35 ft | dawn | Break off the point (6 ft) | Jigging spoon, Small stickbait (slow) |
