350-acre reservoir in Coal County, Oklahoma. The lake tops out around 25 ft. The depth chart comes from published agency bathymetric survey data, so the contours are survey-derived rather than computer-modeled. Here's the year, species by species, as the scoring engine sees it.
Drawn out, this is 350 acres of water rimmed by 12 miles of bank. The 4.6 development index tells the story — a convoluted bank whose fishable edge far outruns the acreage. The shallow band under 15 ft claims about 68% of the surface — that's where the groceries are. Figure 2 mi of water from one end to the other, 1.2 mi at the beam. The water lies in Coal County. Closest neighbour on DepthScout: Atoka Lake, 11 mi southeast of here.
In spring, largemouth bass run shallow here, mostly 2 to 10 ft. Summer pushes them deeper, 8 to 20 ft, and winter fish settle into 8 to 25 ft. Break off the point is the standout, a drop-off at roughly 15 ft, rated prime for winter largemouth bass. Time it for early morning and the evening. 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 (1 ft) | Spinnerbait, Chatterbait |
| Summer | 8 to 20 ft | dawn & dusk | Break off the point (15 ft) | Texas-rigged 10" worm, Deep-diving crankbait |
| Fall | 4 to 15 ft | midday & dawn | Main-lake point (1 ft) | Squarebill crankbait (shad), Spinnerbait |
| Winter | 8 to 25 ft | midday | Break off the point (15 ft) | Blade bait, Jigging spoon |
In spring, channel catfish run shallow here, mostly 3 to 12 ft. Summer pushes them deeper, 8 to 25 ft, and winter fish settle into 8 to 25 ft. Deep basin is the standout, a deep basin at roughly 25 ft, rated prime for winter channel catfish. Time it for after dark and the evening.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 3 to 12 ft | dusk | open water | |
| Summer | 8 to 25 ft | night & dusk | Deep basin (25 ft) | |
| Fall | 8 to 25 ft | dusk | Deep basin (25 ft) | |
| Winter | 8 to 25 ft | midday | Deep basin (25 ft) |
Spring puts crappie in skinny water — 2 to 8 ft is the zone. As the season builds they drop to 10 to 25 ft, wintering in 8 to 25 ft. Winter crappie concentrate at Deep basin, a prime-rated deep basin around 25 ft. Warm-month bites cluster around early morning and the evening. 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 (1 ft) | 1/16 oz jig + tube, Curly-tail grub |
| Summer | 10 to 25 ft | dawn & dusk | Break off the point (15 ft) | Jig trolled/spider-rigged, Small crankbait (trolled) |
| Fall | 8 to 20 ft | dawn | Break off the point (15 ft) | Jig + minnow combo, Small swimbait (1.5-2") |
| Winter | 8 to 25 ft | midday | Deep basin (25 ft) | Tungsten jig + soft plastic, Tiny jigging spoon |
The spring pattern is a shallow one: bluegill in 1 to 6 ft. As the season builds they drop to 4 to 15 ft, wintering in 10 to 25 ft. Top water on the chart: Shallow bay flat, a weed flat in the 1 ft range, prime in spring. Time it for early morning and the evening. Summer baits: a small sponge spider (fly) or a micro tube jig gets it done.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 1 to 6 ft | midday & dusk | Shallow bay flat (1 ft) | 1/32 oz jig + micro plastic, Tiny popper (evenings) |
| Summer | 4 to 15 ft | dawn & dusk | Shallow bay flat (1 ft) | Small sponge spider (fly), Micro tube jig |
| Fall | 6 to 18 ft | midday | Break off the point (15 ft) | Micro jig + waxworm, Small spoon tipped |
| Winter | 10 to 25 ft | midday | Deep basin (25 ft) | Tiny spoon |
Structure-wise the chart holds 6 features, led in depth by Deep basin at roughly 25 ft.

Anglers target largemouth bass, channel catfish, crappie, bluegill on Coalgate City Lake. This isn't a survey of the lake — none is on record for it — but an informed estimate from the species listed for the nearest surveyed lakes in the region, filtered to this lake's depth and habitat.
Break off the point is the top-rated area: a drop-off in about 15 ft of water that rates prime for largemouth bass in winter. The map above holds the full rated-spot list for every species and season.
For largemouth bass, the summer bite is best in early morning and the evening. Each species page section below lists the seasonal windows, and the map shows a live NOW badge when you're inside one.
