Description
The California Department of Parks and Recreation’s Division of Boating and Waterways (DBW) administers this program to protect California reservoirs from invasive mussel infestations. Funding supports prevention planning and implementation that protect drinking-water delivery, agricultural irrigation, and recreational access for boating and fishing. The program is funded solely through Mussel Fee Sticker revenue.
Supported work includes reservoir vulnerability assessments, public education, early-detection monitoring, watercraft inspections, decontamination, and vessel-banding programs. Prevention plans combine monitoring with management of recreational activities and outreach. Priorities include high-risk reservoirs and coordinated regional prevention. Under AB 149, DBW expects eligibility to expand from quagga and zebra mussel prevention to all freshwater invasive mussel prevention in 2027, following regulatory changes. The program remains focused on prevention, not infestation control.
