Del Valle Offers Most Diverse Fishery of Bay Area Lakes L ake Del Valle, a scenic reservoir located 10 miles south of Livermore off Interstate 580 at the edge of the Sunol Regional Wilderness, offers an outstanding array of fish species for anglers to pursue. The reservoir is surrounded by over 5,000 acres of beautiful oak-covered hills at an altitude of 745 feet. My first trip to Del Valle was in 1979. I fished the reservoir with two college friends, Nona Armstrong and Sal Murrietta, and we caught a bunch of bluegill while fishing from a rental boat. Since that time, I have mainly fished Del Valle for trout, but there a lot more species than bluegill and trout at Del Valle. “Del Valle hosts the most diverse fisheries of any Bay Area lake or reservoir,” fishery,” summed up Ed Culver, East Bay Regional Park District (EBRPD) fisheries biologist, in the latest report on the lake’s fish populations. “Anglers target rainbow trout, channel catfish, two species of salmon, bluegill, redear sunfish, black crappie, striped bass, largemouth bass, smallmouth bass, as well as several other species of fish.” The lake features large resident and self-sustaining fish populations of bluegill, redear sunfish, black crappie, striped bass, largemouth bass, and smallmouth bass, along with regular plants of trout and catfish by the park district and the California Department of Fish and Wildlife. Del Valle and New Hogan are unique among California reservoirs in that they feature healthy naturally-repro- ducing populations of stripers. The stripers in Del Valle spawn in the lake’s main tributary, Arroyo Del Valle, and where the creek water merges with the lake waters. The park district and CDFW stock rainbow trout in the fall, winter and spring when the water tempera- ture is cool. The district then stocks channel catfish in the summer months after the surface water tempera- ture becomes too warm to stock rainbows. The amount of catfish and trout planted varies year by year – and the park district plants are dependent on money collected from each fishing permit, weather conditions and fish availability. This year to date, the East Bay Regional Park District (EBRPD) has planted 10,700 lbs. of trout and 3750 lbs. of catfish while the CDFW has stocked 5000 lbs. of trout/ catfish. In 2015, the EBRPD stocked 37750 lbs. of trout and 6225 lbs. of catfish, while the CDFW planted 9000 lbs. of trout/ catfish. In 2016, the EBRPD stocked 24000 lbs. of trout and 4000 lbs. of catfish, while the CDFW planted 15000 lbs. of trout/ catfish. In 2017
