334-acre reservoir in Comanche County, Oklahoma. The lake tops out around 90 ft. The depth chart comes from Oklahoma Water Resources Board 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.
On the chart, Elmer Thomas Lake draws 335 acres inside 9.6 miles of shoreline. The 3.7 development index tells the story — a convoluted bank whose fishable edge far outruns the acreage. The shallow band under 15 ft claims about 36% of the surface — that's where the groceries are. End to end it runs roughly 1.4 mi, about 1.2 mi across. The water lies in Comanche County. For a second option, Lake Lawtonka lies 2 mi north.
In spring, bluegill run shallow here, mostly 1 to 6 ft. Summer pushes them deeper, 4 to 15 ft, and winter fish settle into 10 to 25 ft. Shallow bay flat is the standout, a weed flat at roughly 1 ft, rated prime for spring bluegill. Time it for early morning and the evening. 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 | 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 | Shallow bay flat (1 ft) | Micro jig + waxworm, Small spoon tipped |
| Winter | 10 to 25 ft | midday | open water | Tiny spoon |
The spring pattern is a shallow one: channel catfish in 3 to 12 ft. As the season builds they drop to 8 to 25 ft, wintering in 20 to 40 ft. 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 | open water | |
| Fall | 10 to 30 ft | dusk | open water | |

The spring pattern is a shallow one: largemouth bass in 2 to 10 ft. As the season builds they drop to 8 to 20 ft, wintering in 15 to 35 ft. Top water on the chart: Shallow bay flat, a weed flat in the 1 ft range, good in spring. Time it for early morning and the evening. 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 (1 ft) | Spinnerbait, Chatterbait |
| Summer | 8 to 20 ft | dawn & dusk | open water | Texas-rigged 10" worm, Deep-diving crankbait |
| Fall | 4 to 15 ft | midday & dawn | Main-lake point (1 ft) | Squarebill crankbait (shad), Spinnerbait |
| Winter | 15 to 35 ft | midday | open water | Blade bait, Jigging spoon |
The spring pattern is a shallow one: redear sunfish in 2 to 10 ft. Midsummer fish sit out in 4 to 18 ft before dropping to 10 to 30 ft for winter. The spot to know is Shallow bay flat, a weed flat in about 1 ft of water that rates good for redear sunfish in spring. Plan around early morning and the evening in the warm months. Summer baits: a micro jig or a small soft-plastic nymph gets it done.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 2 to 10 ft | midday & dusk | Shallow bay flat (1 ft) | Micro jig dragged near bottom, Tiny beetle-spin |
| Summer | 4 to 18 ft | dawn & dusk | Shallow bay flat (1 ft) | Micro jig, Small soft-plastic nymph |
| Fall | 7 to 24 ft | midday | open water | Tiny jig tipped with worm, Micro spoon |
| Winter | 10 to 30 ft | midday | open water | Tiny jigging spoon |
Spring puts green sunfish in skinny water — 1 to 8 ft is the zone. Warm water sends them out to 2 to 12 ft; cold water stacks them in 8 to 22 ft. Shallow bay flat is the standout, a weed flat at roughly 1 ft, rated prime for spring green sunfish. Plan around early morning and the evening in the warm months. A micro jig or a small grub covers the summer program.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 1 to 8 ft | midday | Shallow bay flat (1 ft) | Micro jig, Tiny beetle-spin |
| Summer | 2 to 12 ft | dawn & dusk | Shallow bay flat (1 ft) | Micro jig, Small grub |
| Fall | 4 to 16 ft | midday | open water | Small jig, Micro crankbait |
| Winter | 8 to 22 ft | midday | open water | Tiny hair jig, Micro spoon |
