21-acre lake in LaGrange County, Indiana. The lake tops out around 21 ft. The depth chart comes from published agency bathymetric survey data, so the contours are survey-derived rather than computer-modeled. Every species below gets its seasonal read from the same numbers driving the chart.
Shoreline on the chart totals 2.1 miles. A middling shoreline index (1.6) gives it some bays to work without being a maze. The shallow band under 15 ft claims about 73% of the surface — that's where the groceries are. End to end it runs roughly 0.8 mi, about 0.3 mi across. LaGrange County claims this one. Shipshewana Lake sits 2 mi east — the closest neighbouring chart.
Early season largemouth bass use the shallows, holding in 2 to 10 ft. Expect a summer slide to 8 to 20 ft, then a winter hold in 6 to 21 ft. Put Break off the point first on the milk run — a drop-off near 15 ft that grades prime for winter. In summer the feeding windows fall in early morning and the evening. Tie on a texas-rigged 10" worm or a deep-diving crankbait and you're in the game.
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 | 2 to 10 ft | dawn & dusk | Shallow bay flat (1 ft) | Spinnerbait, Chatterbait |
| Summer | 8 to 20 ft | dawn & dusk | Break off the point (15 ft) | Texas-rigged 10" worm, Deep-diving crankbait |
| Fall | 4 to 15 ft | midday & dawn | Main-lake point (1 ft) | Squarebill crankbait (shad), Spinnerbait |
| Winter | 6 to 21 ft chart-limited; documented 15 to 35 ft | midday | Break off the point (15 ft) | Blade bait, Jigging spoon |
Spring bluegill on Cass Lake hold shallow, usually 1 to 6 ft. They move out to 4 to 15 ft in summer and finish the year down in 6 to 21 ft. Put Shallow bay flat first on the milk run — a weed flat near 1 ft that grades prime for spring. The feeding windows run early morning and the evening. The summer box starts with a small sponge spider (fly) or a micro tube jig.

Spring northern pike on Cass Lake hold shallow, usually 2 to 8 ft. By summer they slide out to 8 to 20 ft, and by winter most fish are in 5 to 15 ft. The chart's best answer is Break off the point — drop-off, 15 ft, prime for fall. Prime time lands in early morning and the evening. The summer box starts with a bucktail or a weedless spoon over cabbage.

|---|---|---|---|---|
| Spring | 2 to 8 ft | midday & dawn | Shallow bay flat (1 ft) | #5 inline spinner, Spoon (red/white) |

Spring puts pumpkinseed in skinny water — 1 to 8 ft is the zone. Warm water sends them out to 2 to 10 ft; cold water stacks them in 6 to 18 ft. Shallow bay flat is the standout, a weed flat at roughly 1 ft, rated prime for spring pumpkinseed. Plan around the evening and early morning in the warm months. A micro tube or a sponge spider (fly) covers the summer program.

|---|---|---|---|---|
| Spring | 1 to 8 ft | midday & dusk | Shallow bay flat (1 ft) | Micro jig under a float, Tiny beetle-spin |
| Summer | 2 to 10 ft | dusk & dawn | Shallow bay flat (1 ft) | Micro tube, Sponge spider (fly) |
| Fall | 4 to 14 ft | dusk & dawn | Shallow bay flat (1 ft) | Micro jig + waxworm, Small spoon tipped |

Spring puts rock bass in skinny water — 2 to 10 ft is the zone. Warm water sends them out to 5 to 20 ft; cold water stacks them in 6 to 21 ft.
