Rating depth structure for largemouth bass.
Recent public catches load as you reach this section.
108-acre lake near Sedan. Public southeast Kansas city lake with KBS surveyed bathymetric contours. The lake tops out around 22 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.
The drawn outline gives you 2.9 miles of bank to pick apart. A development index of 2.5 means a maze of bays and points: far more casting targets than a round bowl of the same size. The shallow band under 15 ft claims about 72% of the surface — that's where the groceries are. Tip to tip the water measures near 0.9 mi with a 0.5-mi widest point. It sits in Chautauqua County. Sedan City North Lake sits 1 mi north — the closest neighbouring chart.
When the water first warms, largemouth bass slide up into 2 to 10 ft. Summer is an 8 to 20 ft game here, winter a 7 to 22 ft one. Start at Shallow bay flat. It's a weed flat holding about 9 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.
Depth note: when a documented seasonal range extends below this chart, the table shows the deepest mapped working water, not a verified holding depth.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 2 to 10 ft | dawn & dusk | Shallow bay flat (9 ft) | Spinnerbait, Chatterbait |
| Summer | 8 to 20 ft | dawn & dusk | Shallow bay flat (9 ft) | Texas-rigged 10" worm, Deep-diving crankbait |
| Fall | 4 to 15 ft | midday & dawn | Secondary point (7 ft) | Squarebill crankbait (shad), Spinnerbait |
| Winter | 7 to 22 ft chart-limited; documented 15 to 35 ft | midday | Break off the point (13 ft) | Blade bait, Jigging spoon |
When the water first warms, channel catfish slide up into 3 to 12 ft. Summer is a 7 to 22 ft game here, winter a 7 to 22 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 (9 ft) | |
| Summer | 7 to 22 ft chart-limited; documented 8 to 25 ft | night & dusk | Deep basin (21 ft) | |
| Fall | 7 to 22 ft chart-limited; documented 10 to 30 ft | dusk | Deep basin (21 ft) | |
| Winter | 7 to 22 ft chart-limited; documented 20 to 40 ft | midday | Deep basin (21 ft) |
Come spring, look for crappie tight to the bank in 2 to 8 ft. They move out to 7 to 22 ft in summer and finish the year down in 7 to 22 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 | Back-bay flat (2 ft) | 1/16 oz jig + tube, Curly-tail grub |
| Summer | 7 to 22 ft chart-limited; documented 10 to 25 ft | dawn & dusk | Shallow bay flat (9 ft) | Jig trolled/spider-rigged, Small crankbait (trolled) |
| Fall | 8 to 20 ft | dawn | Shallow bay flat (9 ft) | Jig + minnow combo, Small swimbait (1.5-2") |
| Winter | 7 to 22 ft chart-limited; documented 15 to 35 ft | midday | Deep basin (21 ft) | Tungsten jig + soft plastic, Tiny jigging spoon |
When the water first warms, bluegill slide up into 1 to 6 ft. By summer they slide out to 4 to 15 ft, and by winter most fish are in 7 to 22 ft. If you only fish one area, make it Back-bay flat: a weed flat around 2 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.
