4,009-acre reservoir near Granger. The lake tops out around 37 ft. The depth chart comes from Texas Water Development Board bathymetric survey data, so the contours are survey-derived rather than computer-modeled. The rest of this page walks each species through its year, using the map's own scoring.
Drawn out, this is 4,206 acres of water rimmed by 36 miles of bank. An index of 4 puts the bank firmly in maze territory: point after pocket after cove, every one a casting target. 60% of the surface is littoral (under ~15 ft) — cover, weeds and forage water. End to end it runs roughly 6 mi, about 3.6 mi across. You'll find it in Williamson County. The nearest mapped water is Lake Georgetown, 23 mi to the west.
Start shallow in spring: largemouth bass sit in 2 to 10 ft that time of year. Warm water sends them out to 8 to 20 ft; cold water stacks them in 15 to 35 ft. Top water on the chart: Shallow bay flat, a weed flat in the 5 ft range, prime in spring. Fish it in early morning and the evening and you'll meet the bite. Throw a texas-rigged 10" worm or a deep-diving crankbait until the fish tell you otherwise.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 2 to 10 ft | dawn & dusk | Shallow bay flat (5 ft) | Spinnerbait, Chatterbait |
| Summer | 8 to 20 ft | dawn & dusk | Secondary point (9 ft) | Texas-rigged 10" worm, Deep-diving crankbait |
| Fall | 4 to 15 ft | midday & dawn | Main-lake point (5 ft) | Squarebill crankbait (shad), Spinnerbait |
| Winter | 15 to 35 ft | midday | Old creek channel (14 ft) | Blade bait, Jigging spoon |
Early season white bass use the shallows, holding in 2 to 12 ft. Expect a summer slide to 8 to 25 ft, then a winter hold in 11 to 37 ft. Put San Gabriel River inflow first on the milk run — an inflow / creek mouth near 8 ft that grades prime for spring. In summer the feeding windows fall in early morning and the evening. Tie on a slab spoon or a small topwater (schooling fish) and you're in the game.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 2 to 12 ft | dawn & dusk | San Gabriel River inflow (8 ft) | Curly-tail jig (white), Small lipless crank |
| Summer | 8 to 25 ft | dawn & dusk | Secondary point (9 ft) | Slab spoon, Small topwater (schooling fish) |
| Fall | 6 to 25 ft | dawn & dusk | Secondary point (9 ft) | Jigging spoon, Blade bait |
| Winter | 11 to 37 ft | midday | Deep basin (34 ft) | Jigging spoon (deep), Blade bait |
The spring pattern is a shallow one: crappie in 2 to 8 ft. Midsummer fish sit out in 10 to 25 ft before dropping to 15 to 35 ft for winter. The spot to know is Old creek channel, a creek channel in about 14 ft of water that rates prime for crappie in fall. Plan around early morning and the evening in the warm months. Summer baits: a jig trolled/spider-rigged or a small crankbait (trolled) gets it done.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 2 to 8 ft | midday & dawn | Shallow bay flat (5 ft) | 1/16 oz jig + tube, Curly-tail grub |
| Summer | 10 to 25 ft | dawn & dusk | Old creek channel (14 ft) | Jig trolled/spider-rigged, Small crankbait (trolled) |
| Fall | 8 to 20 ft | dawn | Old creek channel (14 ft) | Jig + minnow combo, Small swimbait (1.5-2") |
| Winter | 15 to 35 ft | midday | Deep basin (34 ft) | Tungsten jig + soft plastic, Tiny jigging spoon |
