11,456-acre reservoir near Somerville. The lake tops out around 29 ft. The depth chart comes from Texas Water Development Board bathymetric survey data, so the contours are survey-derived rather than computer-modeled. Here is how the season plays out for each species, straight from the data behind the map.
Traced from the shoreline, Somerville Lake runs 11,295 acres with 62.2 miles of edge — 4 islands included. A development index of 4.2 means a maze of bays and points: far more casting targets than a round bowl of the same size. The shallow band under 15 ft claims about 59% of the surface — that's where the groceries are. Call it 9.9 mi long by 4.4 mi wide at the broadest reach. You'll find it in Burleson County. Closest neighbour on DepthScout: Fayette County Reservoir, 28 mi south of here.
In spring, largemouth bass run shallow here, mostly 2 to 10 ft. Midsummer fish sit out in 8 to 20 ft before dropping to 9 to 29 ft for winter. Spring largemouth bass concentrate at Shallow bay flat, a prime-rated weed flat around 3 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 (3 ft) | Spinnerbait, Chatterbait |
| Summer | 8 to 20 ft | dawn & dusk | Break off the point (14 ft) | Texas-rigged 10" worm, Deep-diving crankbait |
| Fall | 4 to 15 ft | midday & dawn | Main-lake point (6 ft) | Squarebill crankbait (shad), Spinnerbait |
| Winter | 9 to 29 ft | midday | Break off the point (14 ft) | Blade bait, Jigging spoon |
When the water first warms, white bass slide up into 2 to 12 ft. By summer they slide out to 8 to 25 ft, and by winter most fish are in 9 to 29 ft. If you only fish one area, make it Jerdelle Creek inflow: an inflow / creek mouth around 2 ft that scores prime in spring. In summer the feeding windows fall in early morning and the evening. Keep a slab spoon or a small topwater (schooling fish) rigged through the warm months.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 2 to 12 ft | dawn & dusk | Jerdelle Creek inflow (2 ft) | Curly-tail jig (white), Small lipless crank |
| Summer | 8 to 25 ft | dawn & dusk | Main-lake point (6 ft) | Slab spoon, Small topwater (schooling fish) |
| Fall | 6 to 25 ft | dawn & dusk | Main-lake point (6 ft) | Jigging spoon, Blade bait |
| Winter | 9 to 29 ft | midday | Deep basin (28 ft) | Jigging spoon (deep), Blade bait |
Spring puts white bass & hybrids in skinny water — 3 to 15 ft is the zone. Warm water sends them out to 9 to 29 ft; cold water stacks them in 9 to 29 ft. Deep basin is the standout, a deep basin at roughly 28 ft, rated prime for winter white bass & hybrids. Plan around early morning and the evening in the warm months. A jigging spoon or a topwater (when schooling) covers the summer program.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 3 to 15 ft | midday & dawn | Jerdelle Creek inflow (2 ft) | Rooster tail / inline spinner, Curly-tail jig (white/chartreuse) |
| Summer | 9 to 29 ft | dawn & dusk | Break off the point (14 ft) | Jigging spoon, Topwater (when schooling) |
| Fall | 8 to 25 ft | midday & dawn | Main-lake point (6 ft) | Small blade bait, Jigging spoon |
| Winter | 9 to 29 ft | midday | Deep basin (28 ft) | Jigging spoon, Blade bait (vertical) |
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 9 to 29 ft. Deep basin is the standout, a deep basin at roughly 28 ft, rated prime for winter 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 (3 ft) | 1/16 oz jig + tube, Curly-tail grub |
| Summer | 10 to 25 ft | dawn & dusk | Old creek channel (24 ft) | Jig trolled/spider-rigged, Small crankbait (trolled) |
| Fall | 8 to 20 ft | dawn | Break off the point (14 ft) | Jig + minnow combo, Small swimbait (1.5-2") |
| Winter | 9 to 29 ft | midday | Deep basin (28 ft) | Tungsten jig + soft plastic, Tiny jigging spoon |
The spring pattern is a shallow one: bluegill in 1 to 6 ft. Midsummer fish sit out in 4 to 15 ft before dropping to 10 to 25 ft for winter. The spot to know is Shallow bay flat, a weed flat in about 3 ft of water that rates prime for bluegill in spring. Plan around early morning and the evening in the warm months. 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 (3 ft) | 1/32 oz jig + micro plastic, Tiny popper (evenings) |
| Summer | 4 to 15 ft | dawn & dusk | Shallow bay flat (3 ft) | Small sponge spider (fly), Micro tube jig |
| Fall | 6 to 18 ft | midday | Break off the point (14 ft) | Micro jig + waxworm, Small spoon tipped |
| Winter | 10 to 25 ft | midday | Deep basin (28 ft) | Tiny spoon |
In spring, channel catfish run shallow here, mostly 3 to 12 ft. Midsummer fish sit out in 8 to 25 ft before dropping to 9 to 29 ft for winter. Summer channel catfish concentrate at Old creek channel, a prime-rated creek channel around 24 ft. Fish it in after dark and the evening and you'll meet the bite.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 3 to 12 ft | dusk | Jerdelle Creek inflow (2 ft) | |
| Summer | 8 to 25 ft | night & dusk | Old creek channel (24 ft) | |
| Fall | 9 to 29 ft | dusk | Old creek channel (24 ft) | |
| Winter | 9 to 29 ft | midday | Deep basin (28 ft) |
