Algal Bloom Response Team


This is an example of what blue-green algae can look like, however, it is impossible to determine algal identification and toxicity simply by sight. All blue-green bloom observances should be reported to DEP.

To ensure the health and safety of our state’s residents and visitors, the Florida Department of Environmental Protection is committed to keeping Floridians updated  on current algal blooms and how the state is responding to protect human health, water quality and the environment.

DEP, the five water management districts (WMDs), the Florida Department of Health (DOH), the Florida Fish and Wildlife Conservation Commission (FWC) and the Florida Department of Agriculture and Consumer Services (DACS) all work together to respond to algal blooms, each with a specific role. This “bloom response team” coordinates activities based upon the nature of the bloom event.

DEP and Florida’s water management districts frequently monitor Florida’s water quality, and routinely collect algal bloom samples as soon as they are observed as part of this effort. In addition, staff can be deployed to take additional samples in response to reported blooms – whether from a citizen, other response team agencies or other sources.

The algal bloom response team takes all algal blooms seriously and all federal, state and local agencies will continue to respond as quickly and efficiently as possible to both observed and reported algal blooms to ensure the health and safety of Floridians, visitors and our natural resources.

Recent Monitoring and Testing Information

During the week of Sept. 25, DEP and St. Johns River and performed algal bloom reconnaissance on Doctors Lake (Clay County), Middle River Canal, New River Canal and Tangelo Isle (Broward County), Little Sawgrass Lake and Ten Mile Creek (Brevard County). South Florida Water Management District staff surveyed the northern portion of Lake Okeechobee, both the east and west sides, in, and observed no algae. Four samples were collected for bloom species identification and toxin analysis.  Available results have been posted, including the results for samples collected at the New River Canal site where no toxins were detected. Information regarding these monitoring activities is available on the interactive map.

During the week of Oct. 2 DEP and the water management districts continued to respond to reported algal blooms as well as perform routine monitoring. Persistent blooms are routinely monitored and retested, and staff also regularly review satellite imagery and aerial photography, when available, to inform the development of daily sampling plans.
