334-acre reservoir in Comanche County, Oklahoma. The lake tops out around 90 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.
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 | Deep basin (77 ft) | 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. Top water on the chart: Deep basin, a deep basin in the 77 ft range, good in winter. Time it for after dark and the evening.

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 texas-rigged 10" worm or a deep-diving crankbait gets it done.
