31-acre lake near Cass County. The lake tops out around 25 ft. The contours are modeled from the water's real shoreline and maximum depth. Treat them as a rough guide, and never use them for navigation. Here's the year, species by species, as the scoring engine sees it.
The drawn water covers 31 acres wrapped in 0.9 miles of bank. At index 1.2 the outline is almost a bowl — read the depth changes, not the shoreline. Roughly 44% of the water is 15 ft or less as modeled, the band where the food chain lives. Call it 0.4 mi long by 0.2 mi wide at the broadest reach. Cass County claims this one. If the bite dies, Broadwater Bay is 1 mi to the south.
In spring, walleye run shallow here, mostly 4 to 15 ft. Summer pushes them deeper, 8 to 25 ft, and winter fish settle into 8 to 25 ft. Shoreline break is the standout, a drop-off at roughly 11 ft, rated prime for fall walleye. Time it for the evening and early morning. You won't need more than a crawler harness on bottom bouncer or a deep crankbait (trolled) most summer days.
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 | 4 to 15 ft | dusk & dawn | Shoreline break (11 ft) | 1/8 oz jig + minnow, Hair jig |
| Summer | 8 to 25 ft chart-limited; documented 15 to 35 ft | dusk & dawn | Shoreline break (11 ft) | Crawler harness on bottom bouncer, Deep crankbait (trolled) |
| Fall | 8 to 25 ft chart-limited; documented 12 to 40 ft | dusk & night | Shoreline break (11 ft) | Jigging rap, Jig + big minnow |

When the water first warms, northern pike slide up into 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. If you only fish one area, make it Shallow bay flat: a weed flat around 3 ft that scores prime in spring. In summer the feeding windows fall in early morning and the evening. Keep a bucktail or a weedless spoon over cabbage rigged through the warm months.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 2 to 8 ft | midday & dawn | Shallow bay flat (3 ft) | #5 inline spinner, Spoon (red/white) |
| Summer | 8 to 20 ft | dawn & dusk | Shoreline break (11 ft) | Bucktail, Weedless spoon over cabbage |
| Fall | 6 to 18 ft | midday & dawn | Shoreline break (11 ft) | Big rubber (Bull Dawg style), Husky-style jerkbait |
| Winter | 5 to 15 ft | midday | Shallow bay flat (3 ft) | Tip-ups, Large jigging spoon |
When the water first warms, crappie slide up into 2 to 8 ft. By summer they slide out to 10 to 25 ft, and by winter most fish are in 8 to 25 ft. If you only fish one area, make it Deep basin: a deep basin around 21 ft that scores prime in winter. In summer the feeding windows fall in early morning and the evening. Keep a jig trolled/spider-rigged or a small crankbait (trolled) rigged through the warm months.
