Bureau of Reclamation, Washington.
Formed by Grand Coulee Dam and part of the Columbia Basin Project, this lake contains over 60,000 water-surface acres and 500 miles of shoreline. Available species include walleye, rainbow trout, kokanee, yellow perch, lake whitefish, smallmouth bass, largemouth bass, black crappie, and white sturgeon.
Effective immediately, Reclamation will require all boats launching at Lake Berryessa to participate in a seal program to prevent the spread of invasive mussels. All vessels wishing to launch at Lake Berryessa will be inspected. A red quarantine seal will be applied for 30 days during, which the vessel will not be permitted to launch. Vessels that have finished the 30-day quarantine may return to the lake and have the seal removed by authorized staff and will be allowed to launch. For more information on this updated protocol, please view the press release here: https://www.usbr.gov/newsroom/news-release/5031.
