13-acre lake in Custer County, Nebraska. The lake tops out around 12 ft. The depth chart is built from real state fisheries GPS surveys, so the humps, channels and drop-offs you see are measured, not guessed. The season-by-season read for each species follows, from the map's own numbers.
The outline encloses 13 acres, worked by 0.6 miles of shoreline. A shoreline index of 1.1 says round and simple: fish relate to depth changes here, not shoreline features. There is no deep basin to speak of — the entire surface is under ~15 ft, prime weed water end to end. It sits in Custer County. Brady Lake sits 30 mi south — the closest neighbouring chart.
When the water first warms, largemouth bass slide up into 2 to 10 ft. Summer is a 4 to 12 ft game here, winter a 4 to 12 ft one. Start at Shallow bay flat. It's a weed flat holding about 4 ft of water and rates prime come spring. The feeding windows run early morning and the evening. Keep a texas-rigged 10" worm or a deep-diving crankbait rigged through the warm months.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 2 to 10 ft | dawn & dusk | Shallow bay flat (4 ft) | Spinnerbait, Chatterbait |
| Summer | 4 to 12 ft | dawn & dusk | Shallow bay flat (4 ft) | Texas-rigged 10" worm, Deep-diving crankbait |
| Fall | 3 to 12 ft | midday & dawn | Shallow bay flat (4 ft) | Squarebill crankbait (shad), Spinnerbait |
| Winter | 4 to 12 ft | midday | Deep basin (12 ft) | Blade bait, Jigging spoon |
When the water first warms, bluegill slide up into 1 to 6 ft. By summer they slide out to 3 to 12 ft, and by winter most fish are in 4 to 12 ft. If you only fish one area, make it Shallow bay flat: a weed flat around 4 ft that scores prime in spring. In summer the feeding windows fall in early morning and the evening. Keep a small sponge spider (fly) or a micro tube jig rigged through the warm months.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 1 to 6 ft | midday & dusk | Shallow bay flat (4 ft) | 1/32 oz jig + micro plastic, Tiny popper (evenings) |
| Summer | 3 to 12 ft | dawn & dusk | Shallow bay flat (4 ft) | Small sponge spider (fly), Micro tube jig |
| Fall | 4 to 12 ft | midday | Shallow bay flat (4 ft) | Micro jig + waxworm, Small spoon tipped |
| Winter | 4 to 12 ft | midday | Deep basin (12 ft) | Tungsten ice jig + plastic, Tiny spoon |
When the water first warms, channel catfish slide up into 3 to 12 ft. There's no big seasonal slide here — summer means 4 to 12 ft, winter 4 to 12 ft. Start at Deep basin. It's a deep basin holding about 12 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 (4 ft) | |
| Summer | 4 to 12 ft | night & dusk | Deep basin (12 ft) | |
| Fall | 4 to 12 ft | dusk | Deep basin (12 ft) | |
| Winter | 4 to 12 ft | midday | Deep basin (12 ft) |
