31-acre lake near Lake County. The lake tops out around 31 ft. This chart interpolates between a real shoreline and a known maximum depth. It will point you at likely water, but it is not a navigation product. What the data behind the map says about each species, season by season:
Grub maps at 31 acres behind 1.5 miles of shoreline. A middling shoreline index (1.9) gives it some bays to work without being a maze. Roughly 59% of the water is 15 ft or less as modeled, the band where the food chain lives. Tip to tip the water measures near 0.7 mi with a 0.2-mi widest point. It sits in Lake County. If the bite dies, Splash is 1 mi to the northwest.
Spring smallmouth bass on Grub hold shallow, usually 3 to 12 ft. They move out to 10 to 30 ft in summer and finish the year down in 9 to 31 ft. Put Main-lake point first on the milk run — a point near 8 ft that grades prime for fall. The feeding windows run early morning and the evening. The summer box starts with a drop shot (goby/minnow) or a ned rig.
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 | 3 to 12 ft | dawn & dusk | Main-lake point (8 ft) | Ned rig, Tube jig |
| Summer | 10 to 30 ft | dawn & dusk | Break off the point (14 ft) | Drop shot (goby/minnow), Ned rig |
| Fall | 8 to 25 ft | midday & dawn | Main-lake point (8 ft) | Jerkbait, Blade bait |
| Winter | 9 to 31 ft chart-limited; documented 20 to 45 ft | midday | Break off the point (14 ft) | Blade bait, Hair jig |
Early season largemouth bass use the shallows, holding in 2 to 10 ft. Summer is an 8 to 20 ft game here, winter a 9 to 31 ft one. The chart's best answer is Shallow bay flat — weed flat, 4 ft, prime for spring. Best bite is early morning and the evening. Tie on a texas-rigged 10" worm or a deep-diving crankbait and you're in the game.
