135-acre lake near Jackson County. The lake tops out around 27 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.
The drawn water covers 147 acres wrapped in 2.1 miles of bank. Nearly circular (index 1.2), so the story is the bottom, not the bank. About 77% of the surface sits shallower than 15 ft — that's the weed-and-bait zone. Tip to tip the water measures near 0.7 mi with a 0.4-mi widest point. Jackson County claims this one. Its nearest charted neighbour, Welch Lake, is 3 mi to the northeast.
The spring pattern is a shallow one: yellow perch in 3 to 12 ft. As the season builds they drop to 8 to 27 ft, wintering in 8 to 27 ft. Top water on the chart: Deep basin, a deep basin in the 27 ft range, prime in fall. Time it for early morning. Summer baits: a drop-shot micro plastics or a small spoon tipped with worm gets it done.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 3 to 12 ft | midday & dawn | Shallow bay flat (1 ft) | Small jig + curly tail, Perch-pattern micro crank |
| Summer | 8 to 27 ft | dawn | Deep basin (27 ft) | Drop-shot micro plastics, Small spoon tipped with worm |
| Fall | 8 to 27 ft | midday | Deep basin (27 ft) | Jigging spoon (small), Perch rig / spreader |
| Winter | 8 to 27 ft | midday & dawn | Deep basin (27 ft) | Tungsten jig + spikes, Rattle spoon (small) |
When the water first warms, northern pike slide up into 2 to 8 ft. By summer they slide out to 8 to 20 ft, and by winter most fish are in 5 to 15 ft. If you only fish one area, make it Break off the point: a drop-off around 15 ft that scores prime in fall. In summer the feeding windows fall in early morning and the evening. Keep a bucktail or a weedless spoon over cabbage rigged through the warm months.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 2 to 8 ft | midday & dawn | Shallow bay flat (1 ft) | #5 inline spinner, Spoon (red/white) |
| Summer | 8 to 20 ft | dawn & dusk | Break off the point (15 ft) | Bucktail, Weedless spoon over cabbage |
| Fall | 6 to 18 ft | midday & dawn | Break off the point (15 ft) | Big rubber (Bull Dawg style), Husky-style jerkbait |
| Winter | 5 to 15 ft | midday | Break off the point (15 ft) | Tip-ups, Large jigging spoon |
When the water first warms, smallmouth bass slide up into 3 to 12 ft. By summer they slide out to 8 to 27 ft, and by winter most fish are in 8 to 27 ft. If you only fish one area, make it Break off the point: a drop-off around 15 ft that scores prime in winter. In summer the feeding windows fall in early morning and the evening. Keep a drop shot (goby/minnow) or a ned rig rigged through the warm months.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 3 to 12 ft | dawn & dusk | Main-lake point (1 ft) | Ned rig, Tube jig |
| Summer | 8 to 27 ft | dawn & dusk | Break off the point (15 ft) | Drop shot (goby/minnow), Ned rig |
| Fall | 8 to 25 ft | midday & dawn | Break off the point (15 ft) | Jerkbait, Blade bait |
| Winter | 8 to 27 ft | midday | Break off the point (15 ft) | Blade bait, Hair jig |
Come spring, look for largemouth bass tight to the bank in 2 to 10 ft. Expect a summer slide to 8 to 20 ft, then a winter hold in 8 to 27 ft. Start at Break off the point. It's a drop-off holding about 15 ft of water and rates prime come winter. Prime time lands in early morning and the evening. A texas-rigged 10" worm or a deep-diving crankbait is the honest summer answer here.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 2 to 10 ft | dawn & dusk | Shallow bay flat (1 ft) | Spinnerbait, Chatterbait |
| Summer | 8 to 20 ft | dawn & dusk | Break off the point (15 ft) | Texas-rigged 10" worm, Deep-diving crankbait |
| Fall | 4 to 15 ft | midday & dawn | Main-lake point (1 ft) | Squarebill crankbait (shad), Spinnerbait |
| Winter | 8 to 27 ft | midday | Break off the point (15 ft) | Blade bait, Jigging spoon |
Start shallow in spring: rock bass sit in 2 to 10 ft that time of year. Warm water sends them out to 5 to 20 ft; cold water stacks them in 8 to 27 ft. Top water on the chart: Break off the point, a drop-off in the 15 ft range, prime in fall. Fish it in the evening and you'll meet the bite. Throw a ned rig (small) or a marabou jig until the fish tell you otherwise.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 2 to 10 ft | midday & dawn | Main-lake point (1 ft) | 1/16 oz jig + grub, Small inline spinner |

| Fall | 8 to 22 ft | midday | Break off the point (15 ft) | Small tube jig, Inline spinner |
| Winter | 8 to 27 ft | midday | Deep basin (27 ft) | Tungsten jig + plastic, Small spoon + spike |

If you only fish one area, make it Deep basin: a deep basin around 27 ft that scores prime in winter. In summer the feeding windows fall in early morning and the evening. Keep a jig trolled/spider-rigged or a small crankbait (trolled) rigged through the warm months.
