Palm Beach County's Lar​​gest Estuary 

Spanning 20 miles from North Palm Beach to Ocean Ridge, Lake Worth Lagoon is where ocean water flows in through 2 inlets and mixes with freshwater flowing through 3 major flood control canals that drain over 350,000 acres of land.  This mixture of fresh and salt water turns brackish and is critical habitat to a wide variety of plants and animals.  In addition, the Atlantic Intracoastal Waterway cuts through the estuary as it traverses the east coast and is a source of food, recreation, transportation, employment, and coastal protection for populations living along it.

​What Makes Estuaries Special?

The environment in an estuary is dynamic.  It changes daily - tides move in and out of the inlets - AND seasonally - rainy season drives more freshwater through the canals. Life in Lake Worth Lagoon must adapt to changes in water temperature, salinity, turbidity, depth and flow. 

And while change is what defines an estuary, the result is what makes it highly productive.  Estuaries are the nurseries of the sea by serving as a refuge for species to complete their life-cycle.  Lake Worth Lagoon estuary is a birthing area, safe haven for juveniles to mature, transportation corridor with rest areas during migration, nesting area, and source of food. 

A Lake Worth Saving

Since the late 1990s, ERM has worked to restore lost habitat and improve water quality by managing over 50 large and small scale restoration projects in Lake Worth Lagoon.   To date, over 250 acres of habitat for plants and animals has been added back into the estuary.  Here is a sampling of some of work ERM has completed:

​Restoring Tidal Flat Areas

Johns Island

Originally this low lying tidal area was impacted by soil being placed on it from dredging the Intracoastal Waterway for many years.  ERM restored the island by removing the soil which created optimal conditions for salt marsh, mangrove, seagrass, oysters and tropical maritime habitats.  One of the highlights of this island is a 14 acre oyster bar that filters the water column as freshwater flows into the estuary from inland through the C-51 Canal.  The island is managed by Audubon.​​​​​​​​​​​​​​

Creating Living Shorelines

Where seawalls line the lagoon, ERM's restoration efforts focus on installing elevated planters that flood at high tide.  Mud flats, nooks and crannies in the limestone rock, and the salt marsh grasses all provide habitat for fiddler crabs, birds, and oysters. These projects can be found along publically owned lands within the  City of West Palm Beach at Currie Park (featured) and Osprey Park; City of Lake Worth at Bryant Park, Jewell Cove, and Old Bridge Park; and Town of Lantana at Bicentennial Park, Lyman Park, and Lantana Nature Preserve.

​Exploring the Lagoon

There is much to see and do in the lagoon when you visit one of these ERM restoration areas that have public use amenities offering a range of activities for everyone. 

Munyon Island

Once considered the largest wading bird rookery in South Florida in the 1800s, this island became a destination in the 1900s for wealthy Northerners to recuperate from their ailments at Dr. Munyon's Hotel Hygeia where they would drink his "Paw-Paw Elixir" to heal their aches and pains. In the 1930s and 1960s, the island was impacted when large amounts of soil were placed on it as the Intracoastal Waterway channel was dug out.  In the 1990s, ERM removed the soil, created tidal channels and ponds to increase water flushing, and restored 20 acres of mangrove trees and salt marsh grasses, 23 acres of maritime hammock forest, and 9 acres of underwater seagrass beds.

The island is part of the John D. MacArthur Beach State Park managed by the Florida Park Service.  The best way to visit this historical island once called "Nuctsachoo" or Pelican Island by the Seminole Indians is by kayak which you can rent at the gift shop.

Peanut Island

Since the early 1900s, this site has been the location to store soil removed to create the Lake Worth Inlet and to maintain the Intracoastal Waterway.  As the island grew, exotic trees such as Australian pines infested the property resulting in poor habitat. In 2005, ERM removed soil to create reefs, beaches, dunes, and maritime hammock and mangrove forests on this 79-acre island that gets bathed in the crystal clear Atlantic Ocean waters.

Palm Beach County's Parks and Recreation manages the site which hosts activities such as swimming, snorkeling, and camping.

Snook Islands Natural Area

ERM repurposed 1.2 million cubic yards of sand from Peanut Island and moved it south to fill a large degraded area in the lagoon by the Lake Worth Bridge that had become void of oxygen from years of dredging.  Over 11 acres of mangroves, 2 acres of oysters, 3 acres of salt marsh grass, and 60 acres of seagrass habitat were created north and south of the bridge.

South Cove Natural Area

For years dredging activities just north of the Royal Park Bridge along the Downtown West Palm Beach Waterfront left a 7 acre hole in the lagoon floor that filled in with muck sediment providing little habitat value and an anoxic (lacking oxygen)  environment.  ERM used clean sand to cap (cover and contain) the muck, formed 3 intertidal mangrove and salt marsh islands totaling 2 acres, created 3.5 acres of seagrass habitat and 1 acre of oyster reef habitat.

Ocean Ridge Natural Area

ERM restored this 9.5 acre island south of the Ocean Avenue Bridge in 2006.  The maritime hammock habitat had become degraded over the years due to surrounding development that caused a loss of mangroves and increased exotic invasive vegetation growth.  The natural area is accessible by foot or water traffic (motorized watercraft under 30 feet or kayak/canoe/paddleboard)  making it a very quiet place to visit and observe wildlife.
