1,888-acre reservoir near Washington County. The lake tops out around 25 ft. The contours are modeled from the water's real shoreline and maximum depth. Treat them as a rough guide, and never use them for navigation. Below is the species-by-species picture, pulled from the same data the map uses.
The outline encloses 2,246 acres, worked by 10.9 miles of shoreline. With a 1.6 development index there's bank structure worth casting at, in moderation. Roughly 74% of the water is 15 ft or less as modeled, the band where the food chain lives. Call it 3.7 mi long by 1.5 mi wide at the broadest reach. It sits in Washington County. If the bite dies, Oliver Reservoir is 61 mi to the northwest.
Come spring, look for white bass & hybrids tight to the bank in 3 to 15 ft. They move out to 8 to 25 ft in summer and finish the year down in 8 to 25 ft. If you only fish one area, make it Main-lake point: a point around 8 ft that scores prime in fall. Best bite is early morning and the evening. A jigging spoon or a topwater (when schooling) is the honest summer answer here.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 3 to 15 ft | midday & dawn | Main-lake point (8 ft) | Rooster tail / inline spinner, Curly-tail jig (white/chartreuse) |
| Summer | 8 to 25 ft | dawn & dusk | Main-lake point (8 ft) | Jigging spoon, Topwater (when schooling) |
| Fall | 8 to 25 ft | midday & dawn | Main-lake point (8 ft) | Small blade bait, Jigging spoon |
| Winter | 8 to 25 ft | midday | Deep basin (21 ft) | Jigging spoon, Blade bait (vertical) |
Early season common carp use the shallows, holding in 2 to 10 ft. Expect a summer slide to 3 to 15 ft, then a winter hold in 8 to 25 ft. Put Shallow bay flat first on the milk run — a weed flat near 3 ft that grades prime for 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 | Shallow bay flat (3 ft) | |
| Summer | 3 to 15 ft | dawn & dusk | Shallow bay flat (3 ft) | |
| Fall | 5 to 18 ft | midday | Shallow bay flat (3 ft) | |
| Winter | 8 to 25 ft | midday | Deep basin (21 ft) |
When the water first warms, channel catfish slide up into 3 to 12 ft. Summer is an 8 to 25 ft game here, winter an 8 to 25 ft one. Start at Deep basin. It's a deep basin holding about 21 ft of water and rates prime come winter. The feeding windows run after dark and the evening.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 3 to 12 ft | dusk | Shallow bay flat (3 ft) | |
| Summer | 8 to 25 ft | night & dusk | Deep basin (21 ft) | |
| Fall | 8 to 25 ft | dusk | Deep basin (21 ft) | |
| Winter | 8 to 25 ft | midday | Deep basin (21 ft) |
Come spring, look for crappie tight to the bank in 2 to 8 ft. They move out to 10 to 25 ft in summer and finish the year down in 8 to 25 ft. If you only fish one area, make it Deep basin: a deep basin around 21 ft that scores prime in winter. Best bite is early morning and the evening. A jig trolled/spider-rigged or a small crankbait (trolled) is the honest summer answer here.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 2 to 8 ft | midday & dawn | Shallow bay flat (3 ft) | 1/16 oz jig + tube, Curly-tail grub |
| Summer | 10 to 25 ft | dawn & dusk | Break off the point (11 ft) | Jig trolled/spider-rigged, Small crankbait (trolled) |
| Fall | 8 to 20 ft | dawn | Break off the point (11 ft) | Jig + minnow combo, Small swimbait (1.5-2") |
| Winter | 8 to 25 ft | midday | Deep basin (21 ft) | Tungsten jig + soft plastic, Tiny jigging spoon |
Spring freshwater drum on Prewitt Reservoir hold shallow, usually 5 to 20 ft. By summer they slide out to 7 to 25 ft, and by winter most fish are in 8 to 25 ft. The chart's best answer is Deep basin — deep basin, 21 ft, prime for winter. Prime time lands in the evening. The summer box starts with a jig + crawler combo or a small crankbait (slow).
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 5 to 20 ft | midday & dawn | open water | Jig + curly tail (bounced), Small blade bait |
| Summer | 7 to 25 ft | dusk | Break off the point (11 ft) | Jig + crawler combo, Small crankbait (slow) |
| Fall | 7 to 25 ft | midday | Deep basin (21 ft) | Blade bait (vertical), Jigging spoon |
| Winter | 8 to 25 ft | midday | Deep basin (21 ft) | Jigging spoon (slow) |
The spring pattern is a shallow one: saugeye in 3 to 12 ft. As the season builds they drop to 8 to 22 ft, wintering in 8 to 25 ft. Top water on the chart: Break off the point, a drop-off in the 11 ft range, prime in fall. Time it for the evening and early morning. Summer baits: a crawler harness (shallow) or a jig + crawler gets it done.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 3 to 12 ft | dusk & dawn | Main-lake point (8 ft) | 1/8 oz jig + twister tail, Blade bait |
| Summer | 8 to 22 ft | dusk & dawn | Main-lake point (8 ft) | Crawler harness (shallow), Jig + crawler |
| Fall | 7 to 25 ft | dusk & dawn | Break off the point (11 ft) | Blade bait, Jigging rap |
