After Fish and Wildlife training, district explores boat inspections, brochures and temporary stickers to prevent invasive mussels
Summary
Patrol officer Brandon reported on Fish and Wildlife training about invasive mussels and urged a prevention program: boat inspections, educational brochures, signs at launch points, and possible tamper-evident stickers or quarantine rules to keep mussels out of local waters.
Rancho Murieta staff briefed the board July 2 on steps the district can take to reduce the risk of invasive mussels and other aquatic invasive species after a California Fish and Wildlife training.
Brandon, a patrol officer who attended the training, summarized the biology and pathways of quagga, zebra and golden mussels and said the risk is carried on watercraft, trailers and in standing water. "They could cause us to clog up the water pipes," Brandon said, describing how mussels can foul intake structures and drive long-term maintenance costs.
The training emphasized a clean-drain-dry inspection protocol and showed decontamination procedures that use hot-water sprays (outside at ~140'F and interior at ~120'F) rather than chemicals. Brandon told directors that stationary decontamination units can cost roughly $400,000 while a mobile pressure-wash unit is about $50,000, and he warned that staffing and budget constraints limit the district's ability to run a full-time decontamination station.
Directors discussed lower-cost prevention options: providing Fish and Wildlife brochures and camera-ready graphics for the website and social media, placing signs at formal boat-launch areas, coordinating with RMA and the local fishing club, and piloting an inspection-sticker or tamper-evident seal system with a 30-day quarantine if a seal is tampered with. The board also discussed limiting nonresident boats and using the gate to inspect or hold boats for inspection.
Board members asked staff to work with RMA and Fish and Wildlife on materials and to return with a proposed rollout plan and estimated costs. The board agreed to include basic public-education content in the pipeline and to present a more formal program proposal when staff can identify funding and staffing options.
