Putah Creek

Putah Creek is a tailwater below Monticello Dam on Lake Berryessa, flowing about six miles through an oak-studded canyon before pooling into Lake Solano. The interdam reach holds wild coastal rainbow trout with genetics tracing back to the steelhead that once ran this creek before the dam went in during 1957. These fish are distinctively colored — copper-hued bodies, oversized spots, and crimson flanks from cheek to tail. Most run 10-16 inches, but fish over 20 inches show up regularly, and a few 24-inch-plus rainbows come out each year.

The fishing is technical nymphing — indicator rigs with small flies (sizes 18-22) on 5X-6X fluorocarbon tippet, drifted through glassy runs and weedy channels. The water is characteristically clear with alternating fast pocket water and slow, spooky flats where crawling into position isn't overkill. BWOs and midges are the year-round staples, with Spotted Sedge caddis joining from April through October. Euro nymphing has become increasingly popular, and streamers targeting sculpin-eating rainbows produce some of the creek's largest fish. Dry fly opportunities exist but are secondary to subsurface work.

Located an hour northeast of San Francisco and an hour west of Sacramento, Putah Creek is the closest quality wild trout fishery to the Bay Area. Five county-managed fishing access points line Highway 128 between Winters and the dam. The creek earned Wild Trout Water designation from CDFW in 2014, and it's been catch-and-release with barbless hooks since 2008. Guides and locals observe a voluntary spawning closure from December through February — the fish are on redds, and the community takes it seriously. Flows are dam-controlled: winter sees 60-200 CFS (prime wading), summer jumps to 400-700 CFS for agricultural releases (tough wading, fish the banks). Be aware of the New Zealand mudsnail infestation — thoroughly clean gear before and after fishing.
