10,900-acre reservoir near Manhattan. Big Corps reservoir north of Manhattan, known for white bass runs. The lake tops out around 50 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 rest of this page walks each species through its year, using the map's own scoring.
Tuttle Creek Lake maps at 10,580 acres behind 59.3 miles of shoreline. A development index of 4.1 means a maze of bays and points: far more casting targets than a round bowl of the same size. About 39% of the surface sits shallower than 15 ft — that's the weed-and-bait zone. Tip to tip the water measures near 14.7 mi with a 4.2-mi widest point. It sits in Pottawatomie County. If the bite dies, Pottawatomie County State Fishing Lake No. 1 is 16 mi to the northeast.
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 15 to 35 ft one. Start at Weed flat. It's a weed flat holding about 6 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 | Weed flat (6 ft) | Spinnerbait, Chatterbait |
| Summer | 8 to 20 ft | dawn & dusk | Sharp break (9 ft) | Texas-rigged 10" worm, Deep-diving crankbait |
| Fall | 4 to 15 ft | midday & dawn | Weed flat (6 ft) | Squarebill crankbait (shad), Spinnerbait |
| Winter | 15 to 35 ft | midday | Sharp break (22 ft) | Blade bait, Jigging spoon |
When the water first warms, channel catfish slide up into 3 to 12 ft. Summer is an 8 to 25 ft game here, winter a 20 to 40 ft one. Start at Old creek channel. It's a creek channel holding about 30 ft of water and rates prime come fall. The feeding windows run after dark and the evening.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 3 to 12 ft | dusk | Big Blue River inflow (1 ft) | |
| Summer | 8 to 25 ft | night & dusk | Old creek channel (30 ft) | |
| Fall | 10 to 30 ft | dusk | Old creek channel (30 ft) | |
| Winter | 20 to 40 ft | midday | Old creek channel (30 ft) |
Come spring, look for crappie tight to the bank in 2 to 8 ft. They move out to 10 to 25 ft in summer and finish the year down in 15 to 35 ft. If you only fish one area, make it Old creek channel: a creek channel around 30 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 | Weed flat (6 ft) | 1/16 oz jig + tube, Curly-tail grub |
| Summer | 10 to 25 ft | dawn & dusk | Sharp break (22 ft) | Jig trolled/spider-rigged, Small crankbait (trolled) |
| Fall | 8 to 20 ft | dawn | Sharp break (9 ft) | Jig + minnow combo, Small swimbait (1.5-2") |
| Winter | 15 to 35 ft | midday | Old creek channel (30 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 10 to 25 ft. If you only fish one area, make it Shallow bay flat: a weed flat around 1 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 (1 ft) | 1/32 oz jig + micro plastic, Tiny popper (evenings) |
| Summer | 4 to 15 ft | dawn & dusk | Weed flat (6 ft) | Small sponge spider (fly), Micro tube jig |
| Fall | 6 to 18 ft | midday | Weed flat (6 ft) | Micro jig + waxworm, Small spoon tipped |
| Winter | 10 to 25 ft | midday | Shallow feeding flat (20 ft) | Tungsten ice jig + plastic, Tiny spoon |
The spring pattern is a shallow one: saugeye in 3 to 12 ft. As the season builds they drop to 8 to 22 ft, wintering in 12 to 30 ft. Top water on the chart: Sharp break, a drop-off in the 22 ft range, prime in fall. Time it for the evening and early morning. Summer baits: a crawler harness (shallow) or a jig + crawler gets it done.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 3 to 12 ft | dusk & dawn | Rock reef (6 ft) | 1/8 oz jig + twister tail, Blade bait |
| Summer | 8 to 22 ft | dusk & dawn | Sharp break (22 ft) | Crawler harness (shallow), Jig + crawler |
| Fall | 8 to 28 ft | dusk & dawn | Sharp break (22 ft) | Blade bait, Jigging rap |
| Winter | 12 to 30 ft | dusk & dawn | Old creek channel (30 ft) | Jigging spoon + minnow head, Blade bait |
In spring, white bass run shallow here, mostly 2 to 12 ft. Summer pushes them deeper, 8 to 25 ft, and winter fish settle into 15 to 40 ft. Old creek channel is the standout, a creek channel at roughly 30 ft, rated prime for winter white bass. Time it for early morning and the evening. You won't need more than a slab spoon or a small topwater (schooling fish) most summer days.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 2 to 12 ft | dawn & dusk | Big Blue River inflow (1 ft) | Curly-tail jig (white), Small lipless crank |
| Summer | 8 to 25 ft | dawn & dusk | Sharp break (22 ft) | Slab spoon, Small topwater (schooling fish) |
| Fall | 6 to 25 ft | dawn & dusk | Main-lake point (1 ft) | Jigging spoon, Blade bait |
| Winter | 15 to 40 ft | midday | Old creek channel (30 ft) | Jigging spoon (deep), Blade bait |
