Union Valley Reservoir - Placerville, CA

Lake Information

Fish Species: Rainbow Trout
Union Valley Reservoir, a substantial high-Sierra impoundment near Placerville, California, offers a premier cold-water angling experience within the Eldorado National Forest. Its primary draw is a robust trout fishery, comprising both regularly stocked rainbow trout and elusive brown trout.

A significant feature is the lake's thriving kokanee salmon population, providing spirited light-tackle opportunities, predominantly via specialized trolling techniques at varying depths. Angling methodologies for trout and kokanee involve extensive boat trolling with diverse lures, supplemented by effective bank fishing with bait. Fly fishing is also productive in calmer sections.

Access is facilitated by multiple campgrounds and public boat launches, though lake levels can fluctuate. All anglers must possess a valid California fishing license. Strict adherence to current California Department of Fish and Wildlife (CDFW) regulations, including specific bag limits, size restrictions, and any applicable special management actions for high-elevation lakes, is compulsory for legal compliance and the sustainable management of this valuable recreational resource.
