Bureau of Reclamation, Oregon.
Nearly 30 miles long and up to eight miles wide, Upper Klamath Lake is the largest freshwater body west of the Rockies. It has a surface area of 91,000 acres and 98 miles of shoreline. Recreation facilities are managed for Reclamation by the U. S. Fish and Wildlife Service.
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.
