Rating depth structure for brown bullhead.
Recent public catches load as you reach this section.
45-acre lake near Cass County. The lake tops out around 7 ft. Bathymetry on this water is estimated from its real outline and maximum depth. Use it to shortlist water, then verify with your electronics — and never navigate by it. The rest of this page walks each species through its year, using the map's own scoring.
The drawn water covers 45 acres wrapped in 1.4 miles of bank. A middling shoreline index (1.5) gives it some bays to work without being a maze. Nothing on this chart breaks 15 ft, which makes the whole surface littoral: weeds, bait and ambush cover everywhere. Figure 0.5 mi of water from one end to the other, 0.3 mi at the beam. Cass County claims this one. Its nearest charted neighbour, Diamond, is 1 mi to the northeast.
Spring brown bullhead on Bluebill hold shallow, usually 2 to 7 ft. Depth-wise the year is flat: 2 to 7 ft in summer, 2 to 7 ft once it turns cold. Put Deep basin first on the milk run — a deep basin near 6 ft that grades prime for winter. The feeding windows run after dark and the evening.
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 7 ft chart-limited; documented 2 to 8 ft | dusk & night | Shallow bay flat (3 ft) | |
| Summer | 2 to 7 ft chart-limited; documented 3 to 12 ft | night & dusk | Shallow bay flat (3 ft) | |
| Fall | 2 to 7 ft chart-limited; documented 5 to 15 ft | dusk | Deep basin (6 ft) | |
| Winter | 2 to 7 ft chart-limited; documented 10 to 25 ft | midday | Deep basin (6 ft) |
