There is now another option for boaters hoping to get out on Folsom Lake amid golden mussel restrictions. Boats can now undergo a hot water decontamination — skipping the 30-day quarantine that was previously the only option. The rules are aimed at preventing an infestation of golden mussels, which were recently identified in the Sacramento-San Joaquin Delta and that “pose a significant threat to the ecological health of all waters of the state, its water conveyance systems, infrastructure, and water quality,” California State Parks said. California State Parks lists one location that is authorized to conduct decontaminations and place a green seal on vessels headed for Folsom Lake – Mello Marine. … It’s a service that requires a lot of water and Mello’s setup was designed with that in mind – using pond liners, trenches, filters and holding tanks.
