The Species
About Rainbow Trout
Rainbow trout are California's most widely stocked sport fish, and the South Bay gets its share each winter and spring. The California Department of Fish and Wildlife plants catchable-size rainbows — typically 10 to 12 inches — at Almaden Reservoir during the cooler months. These fish provide excellent action for anglers of all skill levels, and freshly stocked trout hit hard on classic baits.
Planted trout behave differently from wild fish. They tend to school near stocking locations, respond well to strong-scented baits like PowerBait, and are generally less shy than their wild counterparts. They're a great starting point for new anglers and a fun diversion for bass fishermen in the off-season. Check the CDFW fish stocking schedule at wildlife.ca.gov to catch Almaden right after a plant — the bite is incredible for the first few days.
How to Catch Them
Baits, Rigs & Techniques
The #1 stocked trout bait. Mold a small ball onto a treble hook and suspend it 18–24 inches off the bottom with a foam float or egg sinker rig.
Single or clusters of cured salmon eggs on a small hook. Bright red eggs are a classic trout bait that still works.
A piece of nightcrawler drifted under a bobber or fished on the bottom is a reliable all-day trout producer.
Gold or silver inline spoons — Kastmaster, Little Cleo — worked at a medium steady retrieve near the surface.
Rooster Tail, Mepps Aglia — cast and retrieve at a moderate pace. Excellent for covering water from the bank.
Nymphs, woolly buggers, and small streamers produce well. Trout near the surface in cooler months will take dry flies too.
By Season
When to Target Them
CDFW plants trout in December through February at Almaden. The bite is best in the few days after stocking.
Stocking may continue into March–April. Trout also become more active as water warms slightly.
Trout cannot survive in the warm summer water at South Bay reservoirs. They're not available in summer.
Check the CDFW stocking schedule — occasional fall plants occur. Once planted, hit the water quickly.
California Regulations
Rules to Know
- Minimum size: no statewide minimum for hatchery trout (check local regulations)
- Daily bag limit: 5 trout per day statewide in most inland waters
- Hatchery/adipose fin-clipped trout may be kept at locations without catch-and-release restrictions
- Check specific park rules — some Santa Clara County reservoirs are catch-and-release only even for planted trout
- No live bait at county reservoirs — PowerBait, eggs, and worms are dead/prepared bait and are generally permitted
- California Sport Fishing License required for anglers 16 and older
Always verify at CDFW.ca.gov. Check the CDFW fish stocking schedule before heading out.
