3,800-acre reservoir near Santa Rosa. The lake tops out around 100 ft. The depth picture is modeled, anchored to the true shoreline and the water's published max depth — a scouting aid, never a chart to run a boat by. Every species below gets its seasonal read from the same numbers driving the chart.
Shoreline on the chart totals 27.1 miles — 4 islands included. An index of 4.2 puts the bank firmly in maze territory: point after pocket after cove, every one a casting target. About 47% of the surface sits shallower than 15 ft on the modeled chart — that's the weed-and-bait zone. End to end it runs roughly 3.5 mi, about 3.3 mi across. The water lies in Guadalupe County. Closest neighbour on DepthScout: Park Lake, 8 mi south of here.
Come spring, look for walleye tight to the bank in 4 to 15 ft. They move out to 15 to 35 ft in summer and finish the year down in 20 to 40 ft. If you only fish one area, make it Main-lake point: a point around 25 ft that scores prime in fall. Best bite is the evening and early morning. A crawler harness on bottom bouncer or a deep crankbait (trolled) is the honest summer answer here.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 4 to 15 ft | dusk & dawn | open water | 1/8 oz jig + minnow, Hair jig |
| Summer | 15 to 35 ft | dusk & dawn | Main-lake point (25 ft) | Crawler harness on bottom bouncer, Deep crankbait (trolled) |
| Fall | 12 to 40 ft | dusk & night | Main-lake point (25 ft) | Jigging rap, Jig + big minnow |
| Winter | 20 to 40 ft | dusk & dawn | Main-lake point (25 ft) | Jigging spoon + minnow head, Rattle bait |
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 6 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.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 2 to 10 ft | dawn & dusk | Shallow bay flat (6 ft) | Spinnerbait, Chatterbait |
| Summer | 8 to 20 ft | dawn & dusk | Shallow bay flat (6 ft) | Texas-rigged 10" worm, Deep-diving crankbait |
| Fall | 4 to 15 ft | midday & dawn | Shallow bay flat (6 ft) | Squarebill crankbait (shad), Spinnerbait |
| Winter | 15 to 35 ft | midday | Break off the point (45 ft) | Blade bait, Jigging spoon |
Start shallow in spring: smallmouth bass sit in 3 to 12 ft that time of year. Summer pushes them deeper, 10 to 30 ft, and winter fish settle into 20 to 45 ft. The spot to know is Main-lake point, a point in about 25 ft of water that rates prime for smallmouth bass in fall. Warm-month bites cluster around early morning and the evening. Throw a drop shot (goby/minnow) or a ned rig until the fish tell you otherwise.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 3 to 12 ft | dawn & dusk | open water | Ned rig, Tube jig |
| Summer | 10 to 30 ft | dawn & dusk | Main-lake point (25 ft) | Drop shot (goby/minnow), Ned rig |
| Fall | 8 to 25 ft | midday & dawn | Main-lake point (25 ft) | Jerkbait, Blade bait |
| Winter | 20 to 45 ft | midday | Break off the point (45 ft) | Blade bait, Hair jig |
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: Shallow bay flat, a weed flat in the 6 ft range, good in spring. Time it for after dark and the evening.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 3 to 12 ft | dusk | Shallow bay flat (6 ft) | |
| Summer | 8 to 25 ft | night & dusk | Old creek channel (50 ft) | |
| Fall | 10 to 30 ft | dusk | Old creek channel (50 ft) | |
| Winter | 20 to 40 ft | midday | Deep basin (85 ft) |
Start shallow in spring: crappie sit in 2 to 8 ft that time of year. Summer pushes them deeper, 10 to 25 ft, and winter fish settle into 15 to 35 ft. The spot to know is Shallow bay flat, a weed flat in about 6 ft of water that rates prime for crappie in spring. Warm-month bites cluster around early morning and the evening. Throw a jig trolled/spider-rigged or a small crankbait (trolled) until the fish tell you otherwise.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 2 to 8 ft | midday & dawn | Shallow bay flat (6 ft) | 1/16 oz jig + tube, Curly-tail grub |
| Summer | 10 to 25 ft | dawn & dusk | Shallow bay flat (6 ft) | Jig trolled/spider-rigged, Small crankbait (trolled) |
| Fall | 8 to 20 ft | dawn | Shallow bay flat (6 ft) | Jig + minnow combo, Small swimbait (1.5-2") |
| Winter | 15 to 35 ft | midday | Deep basin (85 ft) | Tungsten jig + soft plastic, Tiny jigging spoon |
Spring white bass on Santa Rosa Lake hold shallow, usually 2 to 12 ft. They move out to 8 to 25 ft in summer and finish the year down in 15 to 40 ft. Put Main-lake point first on the milk run — a point near 25 ft that grades prime for fall. The feeding windows run early morning and the evening. The summer box starts with a slab spoon or a small topwater (schooling fish).
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 2 to 12 ft | dawn & dusk | open water | Curly-tail jig (white), Small lipless crank |
| Summer | 8 to 25 ft | dawn & dusk | Main-lake point (25 ft) | Slab spoon, Small topwater (schooling fish) |
