Lakebed Management is responsible for maintaining the public trust lands below the high-water mark in Clear Lake in accordance with Lake County Code, Chapter 23, the Shoreline Ordinance, and Chapter 639 in the State Statutes of 1973. Its purpose is to improve and protect the public's interest in the waters and the bed of the waters in and around Clear Lake, and to insure that the lands will be used for general statewide interests in furtherance of commerce, navigation, fishery, recreation and, wherever possible and appropriate, preservation of the land and waters in their natural state by establishing minimum standards for the construction, alteration, removal and maintenance of structures or other prescribed activities in the lake. The lake bottom lakeward of Zero Rumsey (low-water mark) is land held in the public trust by the State of California for the people of the State, while the land between Zero and 7.79 feet Rumsey (high-water mark) are private, but overlaid with a public trust easement.
Lakebed Management processes permits and encroachment leases for all structures lakeward of 7.79 feet Rumsey, maintains navigation aides, swim markers and swim areas; performs water quality monitoring; and provides support to the Sheriff's Department, Department of Fish and Game, Corps of Engineers, and the State Lands Commission. The Aquatic Plant Management Program and the Invasive Mussels Program are administered by Lakebed Management. The Clear Lake Advisory Committee meets ten times a year to review lake enhancement programs.
In 2010, the Clear Lake Integrated Watershed Management Plan (CLIWMP) was completed. The goal of the CLIWMP is to plan and work toward an environmentally and economically healthy watershed that benefits the community and is sustainable for future generations. The CLIWMP provides background on existing lake and watershed conditions and management, and identifies opportunities to improve watershed conditions and provide guidance for continuing watershed planning efforts.
Lakebed Management is supported from lease payments and permit fees assessed to and collected from Clear Lake shoreline property owners who have placed structures (i.e. - piers, docks, walls, etc.) within the public trust lands (lakeward of Zero Rumsey) which are approximately $164,000 annually. These funds may only be spent on those activities authorized by state statute. The primary expenditures are for the administration of encroachments, maintenance of navigation facilities, and various lake enhancement/monitoring projects. The Aquatic Plant Management Program is funded by permit fees and other County funds. The Invasive Mussel Program is funded entirely by fees.
