California Waterways Without Quagga or Zebra Mussels with Vessel Restrictions to Stop the Spread of Mussels*

Lake County, includes Clear Lake
Requires mandatory inspection of any water vessel prior to launching in a Lake County water body. Applies to all motorized and non-motorized vessels and trailers. All vessels are required to obtain an Inspection Sticker prior to launching. Bans the disposal of live bait and any liquid that contains or has contained live bait into Lake County waters. Lake County Mussel Hotline (707) 263-2556

Lake Casitas
Restricts outside boats, including canoes, kayaks, and float tubes, (those not currently stored or moored at the Recreation Area) from entering the Lake Casitas Recreation Area. This temporary outside boat access restriction is effective for one year. The restriction was adopted on March 4, 2008, by the Casitas Municipal Water District. Local boaters are allowed after inspection and 10 day quarantine of vessel/trailer.
Casitas Municipal Water District's Board of Directors on April 9, 2008 passed a measure to allow outside boats to exclusively use Lake Casitas. Boaters that want to participate in this program are urged to reserve their place on a waiting list by calling (805) 649-2233 Extension 7. Park staff will begin scheduling boat inspections with those on the list.
The new program relies on locks and tags that are designed to ensure boats are not used at any other lake. There will be a one-time $50 charge to cover the cost of the lock and tag. Boats will be locked to a trailer, which can then be stored at a boater's home or at Lake Casitas. Boaters will be able to use the lake as often as they like after their boat goes through the initial clean and dry inspection and a ten day quarantine period. Once a boater decides to use another lake they will need to start the process all over again. This includes an initial inspection and ten day quarantine.
Lake Casitas Recreation Area, (805) 649-2233, ext. 103

Lake Cachuma
All privately owned boats will be inspected. Boats must have a dry bilge, dry wet well, and clean undersides. Live bait limited to night crawlers. Copy of the survey will be kept of file for each boater. Frequent boaters will be given an abbreviated interview. County of Santa Barbara Parks Department (805) 568-2461.
