Any vessel wishing to launch in Lake Berryessa sooner than the required 30-day quarantine period must have a hot-water decontamination performed by certified Lake Berryessa staff. These vessels are allowed to launch immediately following decontamination. Decontaminations performed at another facility will not be valid unless a seal is applied to the vessel and appropriate paperwork is presented.

Scheduling a decontamination is free, however, a credit card is required to hold the reservation. There is a $100 fee for no shows and cancellations with less than 24 hours notice. Due to the high number of no shows and the increased demand, a fee has been instituted. In order to cancel in advance, please use the cancellation or reschedule feature found in your confirmation email. Decontaminations will take place at Steele Canyon Recreation Area, 1605 Steele Canyon Road, 6 miles north off highway 12 and at Markley Cove at 7521 CA-128, Napa, CA 94558. Additional decontamination units are currently being constructed and new locations around the lake will be coming soon.

All decontamination reservations must be made in advance and will be on a first come, first served basis. We are unable to accommodate cancellations made in less than 12 hours prior to the time of the appointment.

If there are no openings available on the calendar, it means that everything is currently booked. Currently we are only opening reservation appointments 1-2 weeks out due to staffing and equipment availability. New decontamination equipment is currently being fabricated and staff are actively being trained in this procedure to increase decontamination availability. As soon as equipment and staff become more available, additional bookings will be posted on the website. Thank you for your patience.
