3,941-acre reservoir near Vassar. Flint Hills reservoir popular for crappie and walleye. The lake tops out around 35 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. Here's the year, species by species, as the scoring engine sees it.
Drawn out, this is 3,942 acres of water rimmed by 41.3 miles of bank. That shoreline is heavily fingered (development index 4.7) — bays, points and pockets everywhere, which multiplies the fishable edge. Roughly 57% of the water is 15 ft or less, the band where the food chain lives. Tip to tip the water measures near 6.3 mi with a 3.6-mi widest point. You'll find it in Osage County. Closest neighbour on DepthScout: Carbondale Lake, 9 mi north of here.
Spring puts largemouth bass in skinny water — 2 to 10 ft is the zone. Warm water sends them out to 8 to 20 ft; cold water stacks them in 15 to 35 ft. Weed flat is the standout, a weed flat at roughly 4 ft, rated prime for spring largemouth bass. Plan around early morning and the evening in the warm months. A texas-rigged 10" worm or a deep-diving crankbait covers the summer program.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 2 to 10 ft | dawn & dusk | Weed flat (4 ft) | Spinnerbait, Chatterbait |
| Summer | 8 to 20 ft | dawn & dusk | Shoreline point (17 ft) | Texas-rigged 10" worm, Deep-diving crankbait |
| Fall | 4 to 15 ft | midday & dawn | Shoreline point (4 ft) | Squarebill crankbait (shad), Spinnerbait |
| Winter | 15 to 35 ft | midday | Break off the point (23 ft) | Blade bait, Jigging spoon |
Spring puts channel catfish in skinny water — 3 to 12 ft is the zone. Warm water sends them out to 8 to 25 ft; cold water stacks them in 11 to 35 ft. Deep basin is the standout, a deep basin at roughly 35 ft, rated prime for winter channel catfish. Plan around after dark and the evening in the warm months.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 3 to 12 ft | dusk | 110 Mile Creek inflow (1 ft) | |
| Summer | 8 to 25 ft | night & dusk | Shallow feeding flat (16 ft) | |
| Fall | 10 to 30 ft | dusk | Old creek channel (34 ft) | |
| Winter | 11 to 35 ft | midday | Deep basin (35 ft) |
In spring, crappie run shallow here, mostly 2 to 8 ft. Midsummer fish sit out in 10 to 25 ft before dropping to 15 to 35 ft for winter. Winter crappie concentrate at Deep basin, a prime-rated deep basin around 35 ft. Fish it in early morning and the evening and you'll meet the bite. You won't need more than a jig trolled/spider-rigged or a small crankbait (trolled) most summer days.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 2 to 8 ft | midday & dawn | Weed flat (4 ft) | 1/16 oz jig + tube, Curly-tail grub |
| Summer | 10 to 25 ft | dawn & dusk | Break off the point (23 ft) | Jig trolled/spider-rigged, Small crankbait (trolled) |
| Fall | 8 to 20 ft | dawn | Shallow feeding flat (16 ft) | Jig + minnow combo, Small swimbait (1.5-2") |
| Winter | 15 to 35 ft | midday | Deep basin (35 ft) | Tungsten jig + soft plastic, Tiny jigging spoon |
Start shallow in spring: bluegill sit in 1 to 6 ft that time of year. Warm water sends them out to 4 to 15 ft; cold water stacks them in 10 to 25 ft. Top water on the chart: Shallow bay flat, a weed flat in the 1 ft range, prime in spring. Fish it in early morning and the evening and you'll meet the bite. Throw a small sponge spider (fly) or a micro tube jig until the fish tell you otherwise.
| 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 | Weed flat (4 ft) | Small sponge spider (fly), Micro tube jig |
| Fall | 6 to 18 ft | midday | Weed flat (5 ft) | Micro jig + waxworm, Small spoon tipped |
| Winter | 10 to 25 ft | midday | Break off the point (23 ft) | Tungsten ice jig + plastic, Tiny spoon |
Spring walleye on Pomona Lake hold shallow, usually 4 to 15 ft. By summer they slide out to 15 to 35 ft, and by winter most fish are in 11 to 35 ft. The chart's best answer is Break off the point — drop-off, 23 ft, prime for fall. Prime time lands in the evening and early morning. The summer box starts with a crawler harness on bottom bouncer or a deep crankbait (trolled).
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 4 to 15 ft | dusk & dawn | 110 Mile Creek inflow (1 ft) | 1/8 oz jig + minnow, Hair jig |
| Summer | 15 to 35 ft | dusk & dawn | Break off the point (23 ft) | Crawler harness on bottom bouncer, Deep crankbait (trolled) |
| Fall | 11 to 35 ft | dusk & night | Break off the point (23 ft) | Jigging rap, Jig + big minnow |
| Winter | 11 to 35 ft | dusk & dawn | Deep basin (35 ft) | Jigging spoon + minnow head, Rattle bait |
Come spring, look for saugeye tight to the bank in 3 to 12 ft. They move out to 8 to 22 ft in summer and finish the year down in 12 to 30 ft. If you only fish one area, make it Break off the point: a drop-off around 23 ft that scores prime in fall. Best bite is the evening and early morning. A crawler harness (shallow) or a jig + crawler is the honest summer answer here.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 3 to 12 ft | dusk & dawn | 110 Mile Creek inflow (1 ft) | 1/8 oz jig + twister tail, Blade bait |
| Summer | 8 to 22 ft | dusk & dawn | Shoreline point (17 ft) | Crawler harness (shallow), Jig + crawler |
| Fall | 8 to 28 ft | dusk & dawn | Break off the point (23 ft) | Blade bait, Jigging rap |
| Winter | 12 to 30 ft | dusk & dawn | Break off the point (23 ft) | Jigging spoon + minnow head, Blade bait |
