848-acre lake near Cook County. The lake tops out around 210 ft. Depth here is modeled from the true shoreline and max depth rather than surveyed; use it to plan, not to navigate. What the data behind the map says about each species, season by season:
Mountain maps at 848 acres behind 15.3 miles of shoreline. A development index of 3.8 means a maze of bays and points: far more casting targets than a round bowl of the same size. Roughly 38% of the water is 15 ft or less as modeled, the band where the food chain lives. End to end it runs roughly 7 mi, about 0.5 mi across. It sits in Cook County. If the bite dies, West Pike is 2 mi to the southeast.
When the water first warms, lake trout slide up into 10 to 40 ft. By summer they slide out to 50 to 120 ft, and by winter most fish are in 20 to 80 ft. If you only fish one area, make it Main-lake point: a point around 53 ft that scores prime in fall. In summer the feeding windows fall in early morning. Keep a white tube jig (deep) or a magnum spoon on downrigger rigged through the warm months.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 10 to 40 ft | dawn & dusk | Main-lake point (53 ft) | Casting spoon over shoals, Jerkbait (shallow) |
| Summer | 50 to 120 ft | dawn | open water | White tube jig (deep), Magnum spoon on downrigger |
| Fall | 10 to 50 ft | dusk & dawn | Main-lake point (53 ft) | Heavy casting spoon, Jigging rap over reefs |
| Winter | 20 to 80 ft | dawn | open water | White tube jig, Airplane jig |
When the water first warms, smallmouth bass slide up into 3 to 12 ft. Summer is a 10 to 30 ft game here, winter a 20 to 45 ft one. The feeding windows run early morning and the evening. Keep a drop shot (goby/minnow) or a ned rig rigged through the warm months.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 3 to 12 ft | dawn & dusk | open water | Ned rig, Tube jig |
| Summer | 10 to 30 ft | dawn & dusk | open water | Drop shot (goby/minnow), Ned rig |
| Fall | 8 to 25 ft | midday & dawn | open water | Jerkbait, Blade bait |
| Winter | 20 to 45 ft | midday | open water | Blade bait, Hair jig |
