Alage Bloom Report for the week of August 24, 2026. The Northern-North IRL (N-NIRL), Central Banana River Lagoon (C-BRL), Southern Banana River Lagoon (S-BRL), Southern-North IRL (S-NIRL), and Northern-Central IRL (N-CIRL) ended the week within low-bloom condition. The Southern Mosquito Lagoon (SML), Central-North IRL (C-NIRL), and Northern Banana River Lagoon (N-BRL) ended the week within mid-bloom conditions. The estimated algae concentrations decreased in the SML, C-NIRL, N-BRL, C-BRL, and S-BRL and increased in the N-NIRL, S-NIRL, and N-CIRL.

Algal blooms are classified as Harmful Algal Blooms when chlorophyll-A concentrations reach high-bloom conditions above 80 µg/L and are persistent for a week or more. Fluctuations of chlorophyll-A concentrations below that level and duration are not unusual in the Indian River Lagoon.

We are happy to announce another project complete with the Flamingo Drive Denitrification Filter. This project adds stormwater retention and filtration to the stormwater system along Flamingo Drive in Satellite Beach. It captures stormwater in a swale, directing it through sediment traps and filters in an underground tank. The added filtration will reduce at least 192 pounds of algae-feeding and muck-creating pollution from entering the lagoon every year.

Algae Bloom Report for the week of August 17, 2026. The Northern-Central IRL (N-CIRL) ended the week within healthy bloom conditions. The Northern-North IRL (N-NIRL), Central Banana River Lagoon (C-BRL), Southern Banana River Lagoon (S-BRL), and Southern-North IRL (S-NIRL) ended the week within low-bloom conditions. The Southern Mosquito Lagoon (SML), Central-North IRL (C-NIRL), and Northern Banana River Lagoon (N-BRL) ended the week within mid-bloom conditions.

The estimated algae concentrations in the Indian River Lagoon (IRL) decreased in the N-NIRL, S-BRL, S-NIRL, and N-CIRL; increased in the SML, C-NIRL, and N-BRL; and there was no change in the C-BRL.

Algal blooms are classified as Harmful Algal Blooms when chlorophyll-A concentrations reach high-bloom conditions above 80 µg/L and are persistent for a week or more. Fluctuations of chlorophyll-A concentrations below that level and duration are not unusual in the Indian River Lagoon.

The FAA is proposing a rule that "would allow the agency to waive requirements from 13 federal laws for certain commercial space licenses and permits. These include NEPA, the Endangered Species Act, parts of the Clean Water Act, the Clean Air Act, the National Historic Preservation Act, and several other environmental and natural resource laws," according to the agency's website.

You can go to https://www.regulations.gov/search?searchTerm=FAA-2026-8614 to view the rule and provide public comment. Comments are open until August 31st, 11:59 pm.

Algae Bloom Report for the week of August 10, 2026. The Northern-Central IRL (N-CIRL) ended the week within healthy bloom conditions. The Northern-North IRL (N-NIRL), Central Banana River Lagoon (C-BRL), Southern Banana River Lagoon (S-BRL), and Southern-North IRL (S-NIRL) ended the week within low-bloom. The Southern Mosquito Lagoon (SML), Central-North IRL (C-NIRL), and Northern Banana River Lagoon (N-BRL) ended the week within mid-bloom conditions. The estimated algae concentrations in the Indian River Lagoon (IRL) decreased in the SML, N-NIRL, N-BRL, C-BRL, S-BRL, and N-CIRL and increased in the C-NIRL and S-NIRL.

For the week of August 3rd, 2026, there was heavy cloud cover which prevented the use of satellite imagery for analysis. Therefore, this week's assessment of Harmful Algal Bloom (HAB) activity in the Indian River Lagoon (IRL) was performed using data from the St. Johns River Water Management District’s (SJRWMD) Continuous Monitoring (CM) stations from Aug 3 to Aug 9.

For the week of Aug 3, monitoring stations IRLB04 & IRLI21 both ended the week with lower RFU readings than the start of the week. Station IRLI13 showed fluctuations throughout the week, but ended the week marginally lower than the start. Station IRLML02 exhibited a marginal increase throughout the week. Station IRLTITUS had the largest increase during the week.

We have another project completed! This project redirects water from the boat ramp parking lot into a nearby stormwater pond. Beemat floating wetlands and sidebank filters were added to the pond to further remove excess nutrient pollution. The project will reduce at least 49 pounds of algae-feeding and muck-creating pollution from entering the lagoon every year.

Algal Bloom Report for the week of July 27, 2026. The Central Banana River Lagoon (C-BRL), Southern Banana River Lagoon (S-BRL), Southern-North IRL (S-NIRL), and Northern-Central IRL (N-CIRL) ended the week within low-bloom conditions. The Southern Mosquito Lagoon (SML), Northern-North IRL (N-NIRL), Central-North IRL (C-NIRL), and Northern Banana River Lagoon (N-BRL) ended the week within mid-bloom conditions. The estimated median Chlorophyll A (ChlA) in the Indian River Lagoon (IRL) decreased across the SML, N-NIRL, C-NIRL, N-BRL, S-BRL, S-NIRL, and N-CIRL. The estimated median ChlA increased in the C-BRL.
