The Indian River Lagoon
The St. Lucie River is part of the larger Indian River Lagoon system, the most diverse estuarine environment in North America, with more than 4,000 plant and animal species. Extensive historical modifications to the St. Lucie River and its watershed have altered the hydrology of the region. As a result, heavy rainfall can bring large influxes of freshwater into the St. Lucie Estuary from stormwater runoff within the basin, Lake Okeechobee releases, or both.
The additional freshwater is often darker in color than Atlantic water, and a distinct line forms where the freshwater meets the salt water. The darkness of the freshwater is caused by tannins in the water. Tannins are natural, organic matter commonly found in freshwater systems. The increased lake water and basin discharges lower salinity levels and reduce water quality in the estuary, causing environmental and economic damage.
Martin County’s Role
Monitor. Communicate. Advocate. Martin County Ecosystems and Restoration Management staff conducts visual checks on sites throughout our area and continues to participate in weekly calls with the Corps and other partner agencies. Additionally, staff reports algae sightings to DEP for notification and consideration of testing. Through our website and social media pages, staff communicates relevant information about the St. Lucie River and estuary and water releases. The Martin County Board of County Commissioners and staff advocate on behalf of our citizens and waterways through our relationships at the state and federal levels.
Beach safety: Martin County Ocean Rescue manages the safety of beach goers at four guarded beaches. For guard tower locations, click here. Advisory signs are posted at all non-guarded beaches. For daily updates on current beach conditions throughout Martin County, call (772) 320-3112 for a pre-recorded message.
Florida Department of Health (DOH): Through the Healthy Beaches Monitoring program, the Martin County Health Department conducts beach and river water sampling to test for enterococci bacteria, which normally inhabit the intestinal tract of humans and animals. If higher than normal levels of bacteria are present, advisory signs will be posted and residents are urged to avoid contact with the water. View DOH's sampling results here.
The Florida Department of Health provides education to the public to prevent and reduce illnesses caused by harmful algae blooms.
Algae bloom toxicity levels: The Florida Department of Environmental Protection (DEP), Florida Fish and Wildlife Conservation Commission (FWC) and Florida’s water management districts collect samples when algae blooms are observed. View DEP's sampling results here.
Citizens are advised, if they have any suspected algae-related illness or health effects due to exposure, to see their physician and report illness to the Florida Poison Control Center at (800) 222-1222.
Report an Algae Bloom
Martin County reminds residents they should avoid any contact with algae blooms and stay out of waters where it is present. Please report algae blooms or sightings to the Florida Department of Environmental Protection (DEP) at (855) 305-3903 or online here.
Report Impacts on Fish and Wildlife
Fish kills or other wildlife impacted by poor water quality should be reported to the Florida Fish and Wildlife Commission (FWC) at (800) 636-0511 or online here.
