2,500-acre reservoir near Byron. The lake tops out around 68 ft. The depth chart comes from published agency bathymetric survey data, so the contours are survey-derived rather than computer-modeled. Every species below gets its seasonal read from the same numbers driving the chart.
Traced from the shoreline, Clifton Court Forebay runs 2,212 acres with 7.9 miles of edge. The basin is a simple one (shoreline index 1.2) — close to a bowl, so the structure on the chart matters more than the bank. Nothing on this chart breaks 15 ft, which makes the whole surface littoral: weeds, bait and ambush cover everywhere. The basin spans about 2.5 mi end to end and 2.1 mi across at its widest. The water lies in Contra Costa County. The nearest mapped water is Bethany Reservoir, 4 mi to the southwest.
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 Deep basin: a deep basin around 51 ft that scores prime in summer. 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 | Secondary point (4 ft) | 3-5 inch baitfish swimbait, Suspending minnow plug |
| Summer | 25 to 60 ft | dawn & dusk | Deep basin (51 ft) | Topwater walker at low light, Paddletail on a light jig |
| Fall | 10 to 35 ft | dawn & dusk | Secondary point (4 ft) | Baitfish swimbait, Metal jig |
| Winter | 20 to 50 ft | midday | Deep basin (51 ft) | Slow paddletail, Bucktail near bottom |
Start shallow in spring: largemouth bass sit in 2 to 10 ft that time of year. Summer pushes them deeper, 8 to 20 ft, and winter fish settle into 15 to 35 ft. The spot to know is Shallow bay flat, a weed flat in about 2 ft of water that rates prime for largemouth bass in spring. Warm-month bites cluster around early morning and the evening. 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 (2 ft) | Spinnerbait, Chatterbait |
| Summer | 8 to 20 ft | dawn & dusk | Break off the point (6 ft) | Texas-rigged 10" worm, Deep-diving crankbait |
| Fall | 4 to 15 ft | midday & dawn | Secondary point (4 ft) | Squarebill crankbait (shad), Spinnerbait |
| Winter | 15 to 35 ft | midday | Break off the point (6 ft) | Blade bait, Jigging spoon |
Start shallow in spring: channel catfish sit in 3 to 12 ft that time of year. Summer pushes them deeper, 8 to 25 ft, and winter fish settle into 20 to 40 ft. The spot to know is Break off the point, a drop-off in about 6 ft of water that rates good for channel catfish in summer. Warm-month bites cluster around after dark and the evening.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 3 to 12 ft | dusk | Shallow bay flat (2 ft) | |
| Summer | 8 to 25 ft | night & dusk | Break off the point (6 ft) | |
| Fall | 10 to 30 ft | dusk | Break off the point (6 ft) | |
| Winter | 20 to 40 ft | midday | open water |
