327-acre state park lake near North Liberty. The lake tops out around 18 ft. The depth chart comes from published agency bathymetric survey data, so the contours are survey-derived rather than computer-modeled. What the data behind the map says about each species, season by season:
The drawn water covers 333 acres wrapped in 7 miles of bank. That shoreline is heavily fingered (development index 2.7) — bays, points and pockets everywhere, which multiplies the fishable edge. Littoral water — the productive band under ~15 ft — makes up 94% of this chart. Tip to tip the water measures near 1.9 mi with a 1-mi widest point. It sits in St. Joseph County. Its nearest charted neighbour, Rupel Lake, is 3 mi to the southwest.
Come spring, look for rainbow trout tight to the bank in 5 to 18 ft. Through summer count on 5 to 18 ft; the winter hold is 4 to 18 ft. Start at Old creek channel. It's a creek channel holding about 7 ft of water and rates prime come summer. Prime time lands in early morning and the evening. A dodger + spoon (deep troll) or a flutter spoon is the honest summer answer here.
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 | 5 to 18 ft chart-limited; documented 5 to 20 ft | dawn & dusk | Creek inflow (2 ft) | Inline spinner (silver), Small spoon |
| Summer | 5 to 18 ft chart-limited; documented 8 to 30 ft | dawn & dusk | Old creek channel (7 ft) | Dodger + spoon (deep troll), Flutter spoon |
| Fall | 5 to 18 ft chart-limited; documented 10 to 35 ft | dawn & dusk | Old creek channel (7 ft) | Casting spoon, Jerkbait over shoals |
| Winter | 4 to 18 ft chart-limited; documented 8 to 40 ft | dawn | Break off the point (12 ft) | Jigging spoon, Tube jig (white) |
Start shallow in spring: walleye sit in 4 to 15 ft that time of year. Warm water sends them out to 5 to 18 ft; cold water stacks them in 5 to 18 ft. Top water on the chart: Break off the point, a drop-off in the 12 ft range, prime in fall. Fish it in the evening and early morning and you'll meet the bite. Throw a crawler harness on bottom bouncer or a deep crankbait (trolled) until the fish tell you otherwise.

|---|---|---|---|---|
| Spring | 4 to 15 ft | dusk & dawn | Creek inflow (2 ft) | 1/8 oz jig + minnow, Hair jig |

Spring smallmouth bass on Worster Lake (Potato Creek) hold shallow, usually 3 to 12 ft. They move out to 5 to 18 ft in summer and finish the year down in 5 to 18 ft. Put Break off the point first on the milk run — a drop-off near 12 ft that grades prime for winter. The feeding windows run early morning and the evening. The summer box starts with a drop shot (goby/minnow) or a ned rig.

Early season channel catfish use the shallows, holding in 3 to 12 ft. Summer is a 5 to 18 ft game here, winter a 5 to 18 ft one. The chart's best answer is Old creek channel — creek channel, 7 ft, prime for summer. Best bite is after dark and the evening.

Spring white bass & hybrids on Worster Lake (Potato Creek) hold shallow, usually 3 to 15 ft. They move out to 5 to 18 ft in summer and finish the year down in 5 to 18 ft. Put Deep basin first on the milk run — a deep basin near 18 ft that grades prime for winter. The feeding windows run early morning and the evening. The summer box starts with a jigging spoon or a topwater (when schooling).

Spring bluegill on Worster Lake (Potato Creek) hold shallow, usually 1 to 6 ft. By summer they slide out to 4 to 15 ft, and by winter most fish are in 5 to 18 ft. The chart's best answer is Shallow bay flat — weed flat, 2 ft, prime for spring. Prime time lands in early morning and the evening. The summer box starts with a small sponge spider (fly) or a micro tube jig.
