43-acre lake near Black Hawk County. Iowa DNR survey water. The lake tops out around 20 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. What follows comes from the same scoring engine that paints the spots above.
Traced from the shoreline, Casey Lake (aka Hickory Hills Lake) runs 43 acres with 1.1 miles of edge. At index 1.1 the outline is almost a bowl — read the depth changes, not the shoreline. About 89% of the surface sits shallower than 15 ft — that's the weed-and-bait zone. End to end it runs roughly 0.4 mi, about 0.2 mi across. The water lies in Tama County. The nearest mapped water is Rodgers Park Lake, 13 mi to the east.
The spring pattern is a shallow one: largemouth bass in 2 to 10 ft. As the season builds they drop to 8 to 20 ft, wintering in 6 to 20 ft. Top water on the chart: Shallow bay flat, a weed flat in the 2 ft range, prime in spring. Time it for early morning and the evening. Summer baits: a texas-rigged 10" worm or a deep-diving crankbait gets it done.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 2 to 10 ft | dawn & dusk | Shallow bay flat (2 ft) | Spinnerbait, Chatterbait |
| Summer | 8 to 20 ft | dawn & dusk | Break off the point (11 ft) | Texas-rigged 10" worm, Deep-diving crankbait |
| Fall | 4 to 15 ft | midday & dawn | Secondary point (3 ft) | Squarebill crankbait (shad), Spinnerbait |
| Winter | 6 to 20 ft | midday | Break off the point (11 ft) | Blade bait, Jigging spoon |
In spring, bluegill run shallow here, mostly 1 to 6 ft. Summer pushes them deeper, 4 to 15 ft, and winter fish settle into 6 to 20 ft. Shallow bay flat is the standout, a weed flat at roughly 2 ft, rated prime for spring bluegill. Time it for early morning and the evening. 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 (2 ft) | 1/32 oz jig + micro plastic, Tiny popper (evenings) |
| Summer | 4 to 15 ft | dawn & dusk | Shallow bay flat (2 ft) | Small sponge spider (fly), Micro tube jig |
| Fall | 6 to 18 ft | midday | Break off the point (11 ft) | Micro jig + waxworm, Small spoon tipped |
| Winter | 6 to 20 ft | midday | Deep basin (19 ft) | Tungsten ice jig + plastic, Tiny spoon |
Start shallow in spring: crappie sit in 2 to 8 ft that time of year. Summer pushes them deeper, 6 to 20 ft, and winter fish settle into 6 to 20 ft. The spot to know is Deep basin, a deep basin in about 19 ft of water that rates prime for crappie in winter. Warm-month bites cluster around early morning and the evening. 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 (2 ft) | 1/16 oz jig + tube, Curly-tail grub |
| Summer | 6 to 20 ft | dawn & dusk | Break off the point (11 ft) | Jig trolled/spider-rigged, Small crankbait (trolled) |
| Fall | 8 to 20 ft | dawn | Break off the point (11 ft) | Jig + minnow combo, Small swimbait (1.5-2") |
| Winter | 6 to 20 ft | midday | Deep basin (19 ft) | Tungsten jig + soft plastic, Tiny jigging spoon |
Come spring, look for yellow perch tight to the bank in 3 to 12 ft. Expect a summer slide to 6 to 20 ft, then a winter hold in 6 to 20 ft. Start at Deep basin. It's a deep basin holding about 19 ft of water and rates prime come fall. Prime time lands in early morning. A drop-shot micro plastics or a small spoon tipped with worm is the honest summer answer here.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 3 to 12 ft | midday & dawn | Shallow bay flat (2 ft) | Small jig + curly tail, Perch-pattern micro crank |
| Summer | 6 to 20 ft | dawn | Deep basin (19 ft) | Drop-shot micro plastics, Small spoon tipped with worm |
| Fall | 6 to 20 ft | midday | Deep basin (19 ft) | Jigging spoon (small), Perch rig / spreader |
| Winter | 6 to 20 ft | midday & dawn | Deep basin (19 ft) | Tungsten jig + spikes, Rattle spoon (small) |
The spring pattern is a shallow one: channel catfish in 3 to 12 ft. As the season builds they drop to 6 to 20 ft, wintering in 6 to 20 ft. Top water on the chart: Deep basin, a deep basin in the 19 ft range, prime in winter. Time it for after dark and the evening.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 3 to 12 ft | dusk | Shallow bay flat (2 ft) | |
| Summer | 6 to 20 ft | night & dusk | Deep basin (19 ft) | |
| Fall | 6 to 20 ft | dusk | Deep basin (19 ft) | |
| Winter | 6 to 20 ft | midday | Deep basin (19 ft) |
Come spring, look for walleye tight to the bank in 4 to 15 ft. They move out to 6 to 20 ft in summer and finish the year down in 6 to 20 ft. If you only fish one area, make it Break off the point: a drop-off around 11 ft that scores prime in fall. Best bite is the evening and early morning. A crawler harness on bottom bouncer or a deep crankbait (trolled) is the honest summer answer here.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 4 to 15 ft | dusk & dawn | Secondary point (3 ft) | 1/8 oz jig + minnow, Hair jig |
| Summer | 6 to 20 ft | dusk & dawn | Break off the point (11 ft) | Crawler harness on bottom bouncer, Deep crankbait (trolled) |
| Fall | 6 to 20 ft | dusk & night | Break off the point (11 ft) | Jigging rap, Jig + big minnow |
| Winter | 6 to 20 ft | dusk & dawn | Deep basin (19 ft) | Jigging spoon + minnow head, Rattle bait |
