Rating depth structure for largemouth bass.
Shared by DepthScout anglers. Exact spots stay private, always.
528-acre lake near Union. The lake tops out around 45 ft. The depth chart comes from published agency bathymetric survey data, so the contours are survey-derived rather than computer-modeled. Species by species, here's what the data says the year looks like.
On the chart, Seven Tree Pond draws 527 acres inside 6.7 miles of shoreline — 3 islands included. Index 2.1 on the shoreline: a few honest points and pockets, nothing labyrinthine. About 29% of the surface sits shallower than 15 ft — that's the weed-and-bait zone. The basin spans about 2.5 mi end to end and 0.6 mi across at its widest. You'll find it in Knox County. The nearest mapped water is Crawford Pond, 1 mi to the east.
Start shallow in spring: brook trout sit in 2 to 15 ft that time of year. Summer pushes them deeper, 10 to 30 ft, and winter fish settle into 3 to 20 ft. The spot to know is Saint George River inflow, an inflow / creek mouth in about 9 ft of water that rates prime for brook trout in spring. Warm-month bites cluster around early morning and the evening. Throw a small spoon fished deep or a trolled lake-clear wobbler + worm until the fish tell you otherwise.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 2 to 15 ft | dawn & dusk | Saint George River inflow (9 ft) | Small inline spinner (gold), Tiny spoon |
| Summer | 10 to 30 ft | dawn & dusk | Saint George River inflow (9 ft) | Small spoon fished deep, Trolled lake-clear wobbler + worm |
| Fall | 2 to 15 ft | midday & dawn | Saint George River inflow (9 ft) | Small spoon (orange), Spinner |
| Winter | 3 to 20 ft | dawn | Saint George River inflow (9 ft) | Small jigging spoon, Tungsten jig + plastic |
In spring, largemouth bass run shallow here, mostly 2 to 10 ft. Midsummer fish sit out in 8 to 20 ft before dropping to 15 to 35 ft for winter. Spring largemouth bass concentrate at Shallow bay flat, a prime-rated weed flat around 6 ft. Fish it in early morning and the evening and you'll meet the bite. You won't need more than a texas-rigged 10" worm or a deep-diving crankbait most summer days.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 2 to 10 ft | dawn & dusk | Shallow bay flat (6 ft) | Spinnerbait, Chatterbait |
| Summer | 8 to 20 ft | dawn & dusk | Main-lake point (14 ft) | Texas-rigged 10" worm, Deep-diving crankbait |
| Fall | 4 to 15 ft | midday & dawn | Main-lake point (14 ft) | Squarebill crankbait (shad), Spinnerbait |
| Winter | 15 to 35 ft | midday | Old creek channel (20 ft) | Blade bait, Jigging spoon |
Spring puts smallmouth bass in skinny water — 3 to 12 ft is the zone. Warm water sends them out to 10 to 30 ft; cold water stacks them in 20 to 45 ft. Main-lake point is the standout, a point at roughly 14 ft, rated prime for fall smallmouth bass. Plan around early morning and the evening in the warm months. A drop shot (goby/minnow) or a ned rig covers the summer program.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 3 to 12 ft | dawn & dusk | Saint George River inflow (9 ft) | Ned rig, Tube jig |
| Summer | 10 to 30 ft | dawn & dusk | Main-lake point (14 ft) | Drop shot (goby/minnow), Ned rig |
| Fall | 8 to 25 ft | midday & dawn | Main-lake point (14 ft) | Jerkbait, Blade bait |
| Winter | 20 to 45 ft | midday | Deep basin (44 ft) | Blade bait, Hair jig |
Start shallow in spring: white perch sit in 4 to 15 ft that time of year. Summer pushes them deeper, 15 to 40 ft, and winter fish settle into 14 to 45 ft. The spot to know is Saint George River inflow, an inflow / creek mouth in about 9 ft of water that rates prime for white perch in spring. Warm-month bites cluster around early morning. Throw a small spinner rig drifted or a 1/8 oz jigging spoon until the fish tell you otherwise.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 4 to 15 ft | dusk | Saint George River inflow (9 ft) | Small jig + curly tail, Inline spinner (silver) |
| Summer | 15 to 40 ft | dawn | Shallow feeding flat (20 ft) | Small spinner rig drifted, 1/8 oz jigging spoon |
| Fall | 15 to 45 ft | midday | Deep basin (44 ft) | Jigging spoon (small), Blade bait |
| Winter | 14 to 45 ft | dusk | Deep basin (44 ft) | Small rattle spoon, Tungsten + spikes |
Spring puts crappie in skinny water — 2 to 8 ft is the zone. Warm water sends them out to 10 to 25 ft; cold water stacks them in 15 to 35 ft. Old creek channel is the standout, a creek channel at roughly 20 ft, rated prime for fall crappie. Plan around early morning and the evening in the warm months. A jig trolled/spider-rigged or a small crankbait (trolled) covers the summer program.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 2 to 8 ft | midday & dawn | Shallow bay flat (6 ft) | 1/16 oz jig + tube, Curly-tail grub |
| Summer | 10 to 25 ft | dawn & dusk | Old creek channel (20 ft) | Jig trolled/spider-rigged, Small crankbait (trolled) |

The spot to know is Shallow bay flat, a weed flat in about 6 ft of water that rates prime for brown bullhead in spring. Plan around after dark and the evening in the warm months.
