Tools for Local Government Agencies:
Harmful Algal Bloom-Related Illness

When local authorities such as county or city officials are aware of a blue-green algae bloom or a waterbody with chronic blue-green algae occurrence, they may choose to post an advisory sign or recommend the lake or beach be closed to in order to protect public health.

These signs are templates designed to assist local authorities with lake or beach advisories and closures due to blue-green algae.
The posting and removal of all signs is at the discretion of the local agency.
