Water Quality
The safety of our visitors is of the utmost importance to us and we have compiled information on the potential conditions that may be present to help you with your trip planning. Please use this page as a resource as it is updated as conditions change. We also encourage you to reach out directly to your hotel or accommodation contact as they will have the most relevant information on whether or not the area in which you are staying may be impacted.
Staying Informed

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, 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.

Protecting Florida Together’s water quality status tool has been developed to deliver to Florida citizens and other interested parties information as it relates to water quality in three major waterbodies in South Florida – the St. Lucie and Caloosahatchee rivers, their respective estuaries and Lake Okeechobee. These waterbodies were selected as they are currently recognized to be among those systems at the greatest risk of adverse impacts due to poor water quality.

Stand with the Locals

Tourism is a vital industry in Martin County that depends on the support of our local community. We’ve got a lot of work ahead of us in protecting our paradise, and we urge you to stand with us in the meantime by continuing to support our many locally owned, tourism-dependent businesses. We are actively promoting the many areas of our county that are untouched and open for business, including attractions, shopping, arts, and events.

As we work to protect our paradise, it is important that we remember and share the things we love most about Martin County. While our waterways are threatened, there are still countless activities to enjoy in the area.
