Quagga and Zebra Mussel Infested Water Bodies in California
Follow these simple steps:
If a boat moved from an infested area will be launched in waters that are not infested with zebra or quagga mussels, the general recommendation is to keep the boat out of water and let it dry for a minimum of 30 days after cleaning all equipment and draining all possible sources of standing water. However, such "quarantine" times may be reduced depending on local temperatures and relative humidity's.
In general, zebra and quagga mussels can survive longer out of water if local conditions are cold and humid than if conditions are hot and dry. This tool estimates recommended quarantine times based on average humidity and temperature zones in the 48 contiguous United States.
If a boat has been in infested waters, please use this tool to estimate the minimum time it should remain out of water (after being cleaned thoroughly), before launching in uninfested waters
