Protecting the River

About the Loxahatchee River

The Loxahatchee River Watershed has a wide variety of habitats and is home to many rare and endangered species, such as the manatee and woodstork. This 260 square mile ecosystem includes the communities of Jupiter, Tequesta, Juno Beach, Jupiter Island, Jupiter Inlet Colony, Jupiter Farms, Hobe Sound and Palm Beach Gardens. Learn more about the river.

WildPine Laboratory

To assist with research programs, the Loxahatchee River District has a state-certified laboratory which provides the needed scientific staff, equipment and professional analysis of daily plant operations, as well as an extensive river research program. Learn more about the WildPine Lab.

Water Quality

The Loxahatchee River District created Project RiverKeeper in 1973 to focus on water quality monitoring within the Loxahatchee River watershed. Data obtained through this program help water managers to evaluate and document the condition and ecological health of the river and to determine the location and extent of water quality issues that require attention.

  • RiverKeeper – The Loxahatchee River District created Project RiverKeeper in 1973 to focus on water quality monitoring within the Loxahatchee River watershed.
  • Datasonde – Since 2004, the Loxahatchee River District has been using automated instrumentation (aka datasondes) to provide near continuous water quality data from key locations throughout the Loxahatchee River.
  • Weekly Bacteria – The Loxahatchee River District collects and tests water quality samples for enterococci bacteria each week throughout Loxahatchee River estuary in popular recreation areas.  This information is for you to use as a guide in deciding when and where to swim and recreate in the River. 

Rainfall & Minimum Flow and Level (MFL)

Rainfall affects river water quality when storm water flows transport pollutants into the river.  Also, seasonal variations in rainfall drive river flow velocities that can significantly influence salinity patterns throughout the Loxahatchee River. 

We have created a tool to explore temporal and spatial rainfall patterns over the Loxahatchee River watershed utilizing the South Florida Water Management District’s radar-based rainfall data named NEXRAD.  To view a map of rainfall across the watershed, compare rainfall maps between two time periods, view tabular summaries of rainfall totals, and rainfall totals over drainage sub-basins click HERE to access the NEXRAD Explorer Tool

The South Florida Water Management District adopted the Minimum Flow and Level Rule that established minimum flow and salinity limits to prevent harm to the habitats in the Northwest Fork of the Loxahatchee River (Chapter 40E-8.221(4), F.A.C.).  We have created an interactive tool to visualize the USGS and SFWMD river flow monitoring data measured at Lainhart Dam and salinity data from the USGS water quality station at River Mile 9.1.  The tool also provides interactive plots of flow data from the SFWMD at the S-46 Flood Control Structure.  Click HERE to access the Minimum Flow and Level (MFL) & S-46 Explorer Tool.


Seagrasses play a critical role in providing sediment stabilization, nutrient cycling, food sources, and nursery grounds for many recreational and commercially important fisheries.

Oyster – Restoration and Monitoring

Oyster reefs provide important benefits to the overall health of the Loxahatchee River by cleaning water, stabilizing shorelines and providing essential fish habitat. Oyster reefs have declined in the river due to a lack of hard surfaces where oyster larvae can attach. The Loxahatchee River District and their partners are working together to restore and conduct research on the oyster reefs in the Loxahatchee River.

River and Watershed Management

This restoration plan is the result of a successful partnership between the South Florida Water Management District (SFWMD), the Florida Department of Environmental Protection Southeast District Office (DEP-SED), the Florida Park Service-District 5 office (FPS-District 5), and the Loxahatchee River Environmental Control District (LRD). Learn more about the Restoration Plan for the Northwest Fork of the Loxahatchee River.

Event Sampling – Stormwater Monitoring

Automated water samplers are used to document nutrient loading to the system following storm events. These autosamplers begin monitoring water quality based on the occurrence of a storm event, and collect water samples every four hours. Learn more about Event Sampling.
