(iv) A final update at the conclusion of any management action.
(c) In addition to owners of an affected water body or property, the department must provide notice of a quarantine declaration to members of the public by any reasonable means for an area subject to a quarantine declaration, such as by publication in a local newspaper, by electronic publication including social media or postings on the department's public website, or by posting signs at the water body. The department must provide updates at reasonable intervals and a final update at the conclusion of the quarantine declaration.
