Structures such as swimming rafts, boat lifts, buoys, slalom courses, ski jumps, etc., which do not extend from shore, cannot be in the water between sunset and sunrise unless allowed under permit issued by county sheriff.
All structures placed under a permit must have the permit number painted on them. In addition, the structure or buoy must either have a light visible in all directions or be reflectorized to reflect light from all directions.
To apply, complete the Raft Permit Application and return with the $5.00/year or $25/5 years to the Sheriff's Office.
