Florida Algal Bloom Response Summary

Sampling Schedule

“Today, July 28, the Department of Environmental Protection will survey and collect samples of observed blooms at Dubois Park in Jupiter. Lee County will survey and collect samples of observed blooms at the Alva Boat Ramp, Franklin Locks, Davis Boat Ramp, North Shore Park and Midpoint Bridge Park.

On July 27, the Florida Fish and Wildlife Conservation Commission (FWC) was scheduled to collect samples at Ft. Pierce Inlet Beach, Blind Creek Park North, Jensen Beach, Bathtub Beach, Hobe Sound Beach and Coral Cove Beach.

On July 26, the South Florida Water Management District surveyed and collected samples of observed blooms at S155, Lake Clarke, St. Lucie Lock S80 and Flying Cow Road bridge west of Wellington.

On July 25, the Florida Department of Environmental Protection surveyed and collected samples of observed blooms on the Caloosahatchee River downstream of the Midpoint Bridge, including the main stem and Iona Cove near Shell Point. Along the St. Lucie, DEP staff surveyed and collected samples of observed blooms downstream from Lock S80. Staff also surveyed Waveland Beach and Carlin Park Beach in response to citizen reports.

The City of Cape Coral surveyed the Cape Coral Yacht Club boat ramp and Bernice Braden Park. DEP staff collected samples of any observed blooms.

On July 25, the South Florida Water Management District surveyed and collected samples of observed blooms on the North Fork of the St. Lucie River.

As part of their routine monitoring, the Florida Fish and Wildlife Conservation Commission collected samples at five fishing piers on the Atlantic coast: Juno Beach, Lake Worth, Deerfield Beach, Anglins and Daina. They also sampled Melody Lane fishing pier on the Indian River.

Sampling Schedule

“Today, Aug. 4, Lee County will be surveying Alva Boat Ramp, Franklin Locks, Davis Boat Ramp, North Shore Park and Midpoint Bridge Park. Samples will be collected if blooms are observed.

On Aug. 3, DEP surveyed the St. Lucie River, including the North and South Forks. Samples were collected if blooms were observed. Staff also conducted regular monthly “long-term monitoring” sampling of  the Caloosahatchee River from Franklin lock all the way to the mouth of the River near Shell Point. Samples were collected if blooms were observed.

The South Florida Water Management District surveyed sites and collected samples if blooms were present on the south side of Lake Okeechobee.

On Aug. 2, DEP responded to a reported algal bloom at the Oslo Boat Ramp in Vero Beach on the Indian River Lagoon.

The South Florida Water Management District surveyed and collected samples if blo observed algal blooms at the St. Lucie Locks (C44S80), Lake Okeechobee (North side) and the C51 canal Flying Cow Ed. Bridge.

On Aug. 1, DEP surveyed and collected samples of observed algal blooms along the St. Lucie River, including the North Fork, the South Fork downstream from lock S80 and in the main stem after the confluence.

The Florida Fish and Wildlife Conservation Commission the Florida Fish and Wildlife Conservation Commission collected samples at five fishing piers on the Atlantic coast: Juno Beach, Lake Worth, Deerfield Beach, Anglins and Daina. They also sampled Melody Lane fishing pier on the Indian River.

The South Florida Water Management District surveyed and collected samples of observed algal blooms on the  Caloosahatchee River at S77, S78 and S79, and at the Port Mayaca Lock.

Sampling Results

To date, a majority of the results continue to indicate low to extremely low levels of toxins. All results are reported to the Florida Department of Health (DOH), the Florida Fish and Wildlife Conservation Commission (FWC) and the Florida Department of Agriculture and Consumer Services (DACS).

On July 26-27, DEP and FWC were deployed to survey and collect samples on the St. Lucie River as well as nearshore marine locations. A total of 13 samples were collected. Extremely low levels of toxins were detected at the St. Lucie River near Dyer Point and at Central Marine in Martin County, which are not recreational swimming areas. While these areas are not located near shore, nor are they recreational swimming areas, DOH always encourages Floridians and visitors to exercise caution to minimize their risk. All other sample results were non-detect for toxins.

Since May 13, 2016, when the South Florida Water Management District (SFWMD) first observed an algal bloom on Lake Okeechobee during their routine sampling, DEP and the SFWMD have regularly responded to and sampled observed and reported algal blooms on Lake Okeechobee, in the St. Lucie River and Estuary and the Caloosahatchee River and Estuary.

Health Effects

DOH takes the lead in determining if a HAB presents a risk to human health. DOH issues health advisories as they determine to be appropriate when toxicity levels are higher and may also post warning signs when Florida Algal blooms affect public beaches or other areas where there is the risk of human exposure. These actions are typically directed out of local county health departments, most often in consultation with staff from DOH’s Aquatic Toxins Program. The World Health Organization considers levels under 10 micrograms/liter to represent a low-level risk for adverse health outcomes from short-term recreational exposures; however, certain sensitive populations (e.g., children, the elderly and immunocompromised populations) may still be at risk even at low concentrations and should avoid any exposure.

DOH also follows up on reports of pets that may have been exposed to a bloom, since these events may predict potential human health threats.”

Who to Contact

The state’s bloom response team encourages residents to report algal blooms so that we can respond quickly and effectively.

  • Florida Department of Environmental Protection collects and analyzes algal bloom samples.
  • Florida Department of Health issues health advisories when toxin levels present a risk to human health.
  • Florida Fish and Wildlife Conservation Commission (FWC) responds to reported fish kills and collects algae samples at nearshore sites.
    • To report a fish kill, contact the Fish Kill Hotline at 800-636-0511.
    • To report any other wildlife injuries, call FWC’s Wildlife Alert at 1-888-404-3922.
  • County governments issue public beach closures. For more information, contact:

Health Effects

The World Health Organization considers levels under 10 micrograms/liter to represent a low-level risk for adverse health outcomes from short-term recreational exposures; however, certain sensitive populations (e.g., children, the elderly and immunocompromised populations) may still be at risk even at low concentrations and should avoid any exposure.

DOH takes the lead in determining if a HAB presents a risk to human health. DOH issues health advisories as they determine to be appropriate when toxicity levels are higher and may also post warning signs when blooms affect public beaches or other areas where there is the risk of human exposure. These actions are typically directed out of local county health departments, most often in consultation with staff from DOH’s staff from Public Health Toxicology Section. DOH also follows up on reports of pets that may have been exposed to a bloom, since these events may predict potential human health threats.”
