Brush piles, bridge pilings and standing timber. The fish fry favorite. Spawning shallow around cover in spring; jigs under a float near buck brush and laydowns.

750 acres south of Livermore, Alameda County, CA. The East Bay's stocked standby.

Fishing Lake Del Valle: the full guide

The regional-park fishery

Del Valle fills a golden canyon south of Livermore: an East Bay Regional Park lake whose heavy trout plants (fall through spring) and resident stripers built the Bay Area's most dependable public fishery. Two million visitors share the park: the fish keep biting anyway.

The trout season

October-May is the program: weekly plants (the park posts them), PowerBait-and-crawler soakers at the classic banks (the dam, swim-beach points), and trollers pulling grubs at 5-25 ft. Derby weekends spike the stakes: holdovers past 5 pounds reward the season's diligent.

Stripers and the warm months

The lake's landlocked stripers (aqueduct arrivals) take over summer: anchovy soakers at the dam, topwater surprises at dawn, fish to 20-plus pounds on live shiners: while largemouth work the tule edges and catfish plants keep the family docks bending. The two-season identity keeps the lake honest year-round.

Park practicalities

The launch, rentals and bait shop run park-standard (entrance fee, quagga inspection): the 10-mph limit keeps water calm: and East Bay heat makes summer mornings the only serious window. Note the water-body advisories posted (mercury guidance on some species): the park signs it clearly.

Common questions

When does Del Valle stock trout?

Roughly October through May, weekly: the park publishes plant days. Winter mornings after a plant are the Bay Area's easiest limits.

Are there big stripers in Del Valle?

Twenty-pound fish come up every summer: aqueduct immigrants grown local. Live bait at the dam or dawn topwater: the lake's adrenaline counterpoint to trout season.
