176-acre lake near Gardner. Kansas public fishing water with KDWP bathymetric map coverage and KBS surveyed contours. The lake tops out around 40 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.
Gardner City Lake's chart carries 4.2 miles of bank. That shoreline is heavily fingered (development index 2.8) — bays, points and pockets everywhere, which multiplies the fishable edge. About 48% of the surface sits shallower than 15 ft — that's the weed-and-bait zone.
When the water first warms, largemouth bass slide up into 2 to 10 ft. Summer is a 8 to 20 ft game here, winter a 15 to 35 ft one. Start at Back-bay flat. It's a weed flat holding about 2 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 | Back-bay flat (2 ft) | Spinnerbait, Chatterbait |
| Summer | 8 to 20 ft | dawn & dusk | Shallow bay flat (18 ft) | Texas-rigged 10" worm, Deep-diving crankbait |
| Fall | 4 to 15 ft | midday & dawn | Main-lake point (9 ft) | Squarebill crankbait (shad), Spinnerbait |
| Winter | 15 to 35 ft | midday | Break off the point (21 ft) | Blade bait, Jigging spoon |
When the water first warms, channel catfish slide up into 3 to 12 ft. Summer is a 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 11 ft of water and rates prime come summer. The feeding windows run after dark and the evening.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 3 to 12 ft | dusk | Creek inflow (2 ft) | |
| Summer | 8 to 25 ft | night & dusk | Old creek channel (11 ft) | |
| Fall | 10 to 30 ft | dusk | Old creek channel (11 ft) | |
| Winter | 20 to 40 ft | midday | Deep basin (38 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 11 ft that scores prime in fall. 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 | 10 to 25 ft | dawn & dusk | Old creek channel (11 ft) | Jig trolled/spider-rigged, Small crankbait (trolled) |
| Fall | 8 to 20 ft | dawn | Old creek channel (11 ft) | Jig + minnow combo, Small swimbait (1.5-2") |
| Winter | 15 to 35 ft | midday | Deep basin (38 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 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.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 1 to 6 ft | midday & dusk | Back-bay flat (2 ft) | 1/32 oz jig + micro plastic, Tiny popper (evenings) |
| Summer | 4 to 15 ft | dawn & dusk | Back-bay flat (2 ft) | Small sponge spider (fly), Micro tube jig |
| Fall | 6 to 18 ft | midday | Shallow bay flat (18 ft) | Micro jig + waxworm, Small spoon tipped |
| Winter | 10 to 25 ft | midday | Shallow bay flat (18 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: Break off the point, a drop-off in the 21-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 | Creek inflow (2 ft) | 1/8 oz jig + twister tail, Blade bait |
| Summer | 8 to 22 ft | dusk & dawn | Main-lake point (9 ft) | Crawler harness (shallow), Jig + crawler |
| Fall | 8 to 28 ft | dusk & dawn | Break off the point (21 ft) | Blade bait, Jigging rap |
| Winter | 12 to 30 ft | dusk & dawn | Old creek channel (11 ft) | Jigging spoon + minnow head, Blade bait |
