32,391-acre bay near Port O'Connor. The water tops out around 14 ft. The depth chart is built from real agency bathymetric surveys, so measured depths remain distinct from source interpolation. The channels, holes and drop-offs come from the source data, not a distance-from-shore model. What the data behind the map says about each species, season by season:
Traced from the shoreline, Espiritu Santo Bay runs 31,896 acres with 67.6 miles of edge — 15 islands included. The 2.7 development index tells the story — a convoluted bank whose fishable edge far outruns the acreage. The whole water is littoral — nothing here runs deeper than ~15 ft, so it's all weed-and-bait territory. Figure 15.9 mi of water from one end to the other, 5.3 mi at the beam. The nearest mapped water is Matagorda Bay, 19 mi to the northeast.
Start shallow in spring: red drum (redfish) sit in 1 to 8 ft that time of year. Summer pushes them deeper, 2 to 12 ft, and winter fish settle into 3 to 14 ft. The spot to know is Feeding flat, a feeding flat in about 8 ft of water that rates prime for red drum (redfish) in spring. Warm-month bites cluster around early morning and the evening. Throw a weedless gold spoon or a paddletail swimbait until the fish tell you otherwise.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 1 to 8 ft | dawn & dusk | Feeding flat (8 ft) | Gold weedless spoon, Paddletail on 1/4 oz jighead |
| Summer | 2 to 12 ft | dawn & dusk | Shallow bay flat (4 ft) | Weedless gold spoon, Paddletail swimbait |
| Fall | 2 to 14 ft | dawn & midday | Gravel shoal (2 ft) | 1/2 oz spoon (schools), Big paddletail |
| Winter | 3 to 14 ft | midday & dawn | Deep basin (11 ft) | Scented soft plastic on 1/8 oz head, Slow-rolled paddletail |
Early season spotted seatrout use the shallows, holding in 2 to 10 ft. Expect a summer slide to 4 to 14 ft, then a winter hold in 4 to 14 ft. Put Shallow bay flat first on the milk run — a weed flat near 4 ft that grades prime for spring. In summer the feeding windows fall in early morning. Tie on a popping cork + shrimp or a 1/4 oz jighead + paddletail (deep grass edge) and you're in the game.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 2 to 10 ft | dawn & dusk | Shallow bay flat (4 ft) | Topwater walker, Suspending twitchbait |
| Summer | 4 to 14 ft | dawn | Sharp break (4 ft) | Popping cork + shrimp, 1/4 oz jighead + paddletail (deep grass edge) |
| Fall | 3 to 12 ft | dawn | Shallow bay flat (4 ft) | Popping cork rig, Soft plastic jerkbait |
| Winter | 4 to 14 ft | midday & dusk | Deep basin (11 ft) | Suspending twitchbait (long pauses), Scented plastic crawled on bottom |
Spring puts southern flounder in skinny water — 2 to 14 ft is the zone. Summer fish stay in 2 to 14 ft, and winter fish hold in 4 to 14 ft. Summer southern flounder concentrate at Break off the point, a prime-rated drop-off around 3 ft. Warm-month bites cluster around early morning. A jighead + gulp swimming mullet or a bucktail tipped with shrimp covers the summer program.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 2 to 14 ft | dawn | Break off the point (3 ft) | 1/4 oz jighead + paddletail (white/chartreuse), Bucktail + Gulp shrimp |
| Summer | 2 to 14 ft | dawn | Break off the point (3 ft) | Jighead + Gulp swimming mullet, Bucktail tipped with shrimp |
| Fall | 3 to 14 ft | midday | Break off the point (3 ft) | 3/8 oz bucktail + Gulp (passes), Big paddletail on the jetty edge |
| Winter | 4 to 14 ft | midday | Deep basin (11 ft) | Slow jig + scented grub in the holes |
Structure-wise the chart holds 12 features, led in depth by Deep basin at roughly 11 ft.

Espiritu Santo Bay is about 14 ft (4 m) deep at its deepest point. The depth chart is built from real agency bathymetric surveys, so measured depths remain distinct from source interpolation. The contours reflect measured and quality-assessed source depths.
Anglers target red drum (redfish), spotted seatrout, southern flounder on Espiritu Santo Bay.
Feeding flat is the top-rated area: a feeding flat in about 8 ft of water that rates prime for red drum (redfish) in spring. The map above holds the full rated-spot list for every species and season.
For red drum (redfish), the summer bite is best in early morning and the evening. Each species page section below lists the seasonal windows, and the map shows a live NOW badge when you're inside one.
