1,439-acre reservoir near Bloomington; 2025 GPS/sonar survey by the Lake Lemon Conservancy District. The lake tops out around 27 ft. The depth data here comes from a modern GPS/sonar survey of 2025, provided by the lake's own community organization. Here is how the season plays out for each species, straight from the data behind the map.
Drawn out, this is 1,393 acres of water rimmed by 18.1 miles of bank. An index of 3.5 puts the bank firmly in maze territory: point after pocket after cove, every one a casting target. The shallow band under 15 ft claims about 90% of the surface — that's where the groceries are. Call it 4.1 mi long by 1.3 mi wide at the broadest reach. You'll find it in Monroe County. The nearest mapped water is Yellowwood Lake, 6 mi to the southeast.
The spring pattern is a shallow one: largemouth bass in 2 to 10 ft. Midsummer fish sit out in 8 to 20 ft before dropping to 8 to 27 ft for winter. The spot to know is Shallow bay flat, a weed flat in about 7 ft of water that rates prime for largemouth bass in spring. Plan around early morning and the evening in the warm months. Summer baits: a texas-rigged 10" worm or a deep-diving crankbait gets it done.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 2 to 10 ft | dawn & dusk | Shallow bay flat (7 ft) | Spinnerbait, Chatterbait |
| Summer | 8 to 20 ft | dawn & dusk | Break off the point (9 ft) | Texas-rigged 10" worm, Deep-diving crankbait |
| Fall | 4 to 15 ft | midday & dawn | Secondary point (3 ft) | Squarebill crankbait (shad), Spinnerbait |
| Winter | 8 to 27 ft | midday | Break off the point (9 ft) | Blade bait, Jigging spoon |
Start shallow in spring: crappie sit in 2 to 8 ft that time of year. Warm water sends them out to 10 to 25 ft; cold water stacks them in 8 to 27 ft. Top water on the chart: Deep basin, a deep basin in the 21 ft range, prime in winter. Fish it in early morning and the evening and you'll meet the bite. Throw a jig trolled/spider-rigged or a small crankbait (trolled) until the fish tell you otherwise.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 2 to 8 ft | midday & dawn | Shallow bay flat (7 ft) | 1/16 oz jig + tube, Curly-tail grub |
| Summer | 10 to 25 ft | dawn & dusk | Deep basin (21 ft) | Jig trolled/spider-rigged, Small crankbait (trolled) |
| Fall | 8 to 20 ft | dawn | Break off the point (9 ft) | Jig + minnow combo, Small swimbait (1.5-2") |
| Winter | 8 to 27 ft | midday | Deep basin (21 ft) | Tungsten jig + soft plastic, Tiny jigging spoon |
In spring, bluegill run shallow here, mostly 1 to 6 ft. Midsummer fish sit out in 4 to 15 ft before dropping to 10 to 25 ft for winter. Spring bluegill concentrate at Back-bay flat, a prime-rated weed flat around 4 ft. Fish it in early morning and the evening and you'll meet the bite. You won't need more than a small sponge spider (fly) or a micro tube jig most summer days.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 1 to 6 ft | midday & dusk | Back-bay flat (4 ft) | 1/32 oz jig + micro plastic, Tiny popper (evenings) |
| Summer | 4 to 15 ft | dawn & dusk | Shallow bay flat (7 ft) | Small sponge spider (fly), Micro tube jig |
| Fall | 6 to 18 ft | midday | Shallow bay flat (7 ft) | Micro jig + waxworm, Small spoon tipped |
| Winter | 10 to 25 ft | midday | Deep basin (21 ft) | Tungsten ice jig + plastic, Tiny spoon |
The spring pattern is a shallow one: channel catfish in 3 to 12 ft. Midsummer fish sit out in 8 to 25 ft before dropping to 8 to 27 ft for winter. The spot to know is Deep basin, a deep basin in about 21 ft of water that rates prime for channel catfish in winter. Plan around after dark and the evening in the warm months.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 3 to 12 ft | dusk | Shallow bay flat (7 ft) | |
| Summer | 8 to 25 ft | night & dusk | Deep basin (21 ft) | |
| Fall | 8 to 27 ft | dusk | Deep basin (21 ft) | |
| Winter | 8 to 27 ft | midday | Deep basin (21 ft) |
Structure-wise the chart holds 7 features, led in depth by Deep basin at roughly 21 ft.
