DEQ uses the information in this form to respond to potential harmful blooms.

Freshwater cyanobacterial harmful algal blooms occur worldwide and are associated with food web alterations, hypoxia, human respiratory irritation, and taste and odor of potable water as a result of ingestion or skin exposure during recreational activities. Rapid detection of potentially harmful blooms is essential to protect humans and animals from exposure. Information about potential for exposure, such as bloom duration, frequency, and extent, is especially critical for management decisions during periods of limited resources and funding. Successful assessment by satellites may provide a first-line of defense indicator for human and ecological health protection.
