65,494-acre bay near Vallejo. The water tops out around 79 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. The rest of this page walks each species through its year, using the map's own scoring.
On the chart, San Pablo Bay draws 65,318 acres inside 48.6 miles of shoreline. At index 1.4 the outline is almost a bowl — read the depth changes, not the shoreline. 83% of the surface is littoral (under ~15 ft) — cover, weeds and forage water. Figure 12.9 mi of water from one end to the other, 11.9 mi at the beam. For a second option, Petaluma River lies 11 mi northwest.
When the water first warms, striped bass slide up into 5 to 20 ft. By summer they slide out to 25 to 60 ft, and by winter most fish are in 20 to 50 ft. If you only fish one area, make it Main-lake point: a point around 20 ft that scores prime in fall. In summer the feeding windows fall in early morning and the evening. Keep a topwater walker at low light or a paddletail on a light jig rigged through the warm months.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 5 to 20 ft | dawn & dusk | Main-lake point (20 ft) | 3-5 inch baitfish swimbait, Suspending minnow plug |
| Summer | 25 to 60 ft | dawn & dusk | Break off the point (24 ft) | Topwater walker at low light, Paddletail on a light jig |
| Fall | 10 to 35 ft | dawn & dusk | Main-lake point (20 ft) | Baitfish swimbait, Metal jig |
| Winter | 20 to 50 ft | midday | Old creek channel (24 ft) | Slow paddletail, Bucktail near bottom |
Spring puts california halibut in skinny water — 5 to 30 ft is the zone. As the season builds they drop to 8 to 40 ft, wintering in 15 to 60 ft. Spring california halibut concentrate at Shallow feeding flat, a prime-rated feeding flat around 20 ft. Warm-month bites cluster around early morning. A paddletail dragged on sand or a bucktail + strip covers the summer program.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 5 to 30 ft | midday & dawn | Shallow feeding flat (20 ft) | Swimbait on 1/2-1 oz head (drifted), Hair raiser jig |
| Summer | 8 to 40 ft | dawn | Shallow feeding flat (20 ft) | Paddletail dragged on sand, Bucktail + strip |
| Fall | 10 to 50 ft | midday | Break off the point (24 ft) | Heavier jig + swimbait (channels), Drifted bucktail |
| Winter | 15 to 60 ft | midday | Break off the point (24 ft) | Slow-dragged swimbait in deep channels |
When the water first warms, leopard shark slide up into 3 to 25 ft. There's no big seasonal slide here — summer means 2 to 25 ft, winter 8 to 45 ft. Start at Shallow feeding flat. It's a feeding flat holding about 20 ft of water and rates prime come spring. The feeding windows run early morning and the evening. Keep a scented bottom jig rigged through the warm months.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 3 to 25 ft | dusk | Shallow feeding flat (20 ft) | Scented shrimp jig crawled on bottom |
| Summer | 2 to 25 ft | dawn & dusk | Shallow feeding flat (20 ft) | Scented bottom jig |
| Fall | 4 to 35 ft | dawn & dusk | Shallow feeding flat (20 ft) | Scented shrimp or baitfish jig |
| Winter | 8 to 45 ft | midday | Break off the point (24 ft) | Slow scented bottom jig |
Structure-wise the chart holds 19 features, led in depth by Deep basin at roughly 75 ft.

San Pablo Bay is about 79 ft (24 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 striped bass, california halibut, leopard shark on San Pablo Bay.
Main-lake point is the top-rated area: a point in about 20 ft of water that rates prime for striped bass in fall. Every other rated spot, per species and season, is on the map above.
For striped bass, 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.
