68-acre lake near Thayer. Public southeast Kansas city lake with KBS surveyed bathymetric contours. The lake tops out around 30 ft. The depth chart comes from published agency bathymetric survey data, so the contours are survey-derived rather than computer-modeled. Here is how the season plays out for each species, straight from the data behind the map.
The drawn outline gives you 2.2 miles of bank to pick apart. With a shoreline index of 2.5, this water is all arms and coves — edge habitat well beyond its acreage. The shallow band under 15 ft claims about 56% of the surface — that's where the groceries are. End to end it runs roughly 0.7 mi, about 0.3 mi across. You'll find it in Neosho County. The nearest mapped water is Thayer Old City Lake, 1 mi to the east.
The spring pattern is a shallow one: largemouth bass in 2 to 10 ft. Midsummer fish sit out in 8 to 20 ft before dropping to 9 to 30 ft for winter. The spot to know is Break off the point, a drop-off in about 8 ft of water that rates prime for largemouth bass in winter. Plan around early morning and the evening in the warm months. Summer baits: a texas-rigged 10" worm or a deep-diving crankbait gets it done.
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 (1 ft) | Spinnerbait, Chatterbait |
| Summer | 8 to 20 ft | dawn & dusk | Break off the point (8 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 | 9 to 30 ft chart-limited; documented 15 to 35 ft | midday | Break off the point (8 ft) | Blade bait, Jigging spoon |
The spring pattern is a shallow one: channel catfish in 3 to 12 ft. Midsummer fish sit out in 8 to 25 ft before dropping to 9 to 30 ft for winter. The spot to know is Deep basin, a deep basin in about 30 ft of water that rates prime for channel catfish in winter. Plan around after dark and the evening in 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 | 3 to 12 ft | dusk | open water | |
| Summer | 8 to 25 ft | night & dusk | Break off the point (8 ft) | |
| Fall | 10 to 30 ft | dusk | Deep basin (30 ft) | |
| Winter | 9 to 30 ft chart-limited; documented 20 to 40 ft | midday | Deep basin (30 ft) |
Start shallow in spring: crappie sit in 2 to 8 ft that time of year. Warm water sends them out to 10 to 25 ft; cold water stacks them in 9 to 30 ft. Top water on the chart: Deep basin, a deep basin in the 30 ft range, prime in winter. Fish it in early morning and the evening and you'll meet the bite. Throw a jig trolled/spider-rigged or a small crankbait (trolled) until the fish tell you otherwise.

| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 2 to 8 ft | midday & dawn | Shallow bay flat (1 ft) | 1/16 oz jig + tube, Curly-tail grub |
| Summer | 10 to 25 ft | dawn & dusk | Break off the point (8 ft) | Jig trolled/spider-rigged, Small crankbait (trolled) |
| Fall | 8 to 20 ft | dawn | Break off the point (8 ft) | Jig + minnow combo, Small swimbait (1.5-2") |
| Winter | 9 to 30 ft chart-limited; documented 15 to 35 ft | midday | Deep basin (30 ft) | Tungsten jig + soft plastic, Tiny jigging spoon |
In spring, bluegill run shallow here, mostly 1 to 6 ft. Midsummer fish sit out in 4 to 15 ft before dropping to 10 to 25 ft for winter. Spring bluegill concentrate at Shallow bay flat, a prime-rated weed flat around 1 ft. Fish it in early morning and the evening and you'll meet the bite. You won't need more than a small sponge spider (fly) or a micro tube jig most summer days.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 1 to 6 ft | midday & dusk | Shallow bay flat (1 ft) | 1/32 oz jig + micro plastic, Tiny popper (evenings) |
| Summer | 4 to 15 ft | dawn & dusk | Shallow bay flat (1 ft) | Small sponge spider (fly), Micro tube jig |
| Fall | 6 to 18 ft | midday | Break off the point (8 ft) | Micro jig + waxworm, Small spoon tipped |
| Winter | 10 to 25 ft | midday | Deep basin (30 ft) | Tiny spoon |
