Blooms can vary in appearance, sometimes looking like spilled paint, mats, foam, or surface scum. Blooms can range in color from blue and bright green to brown and red. Some blooms produce a foul odor. If you observe a blue-green algae bloom, report it on bloomWatch or contact your DEQ regional office.
