Watershed Management / Grassy Waters Preserve

The Watershed Management Division has the responsibility of ensuring that Grassy Waters Preserve continues to meet both human and ecological freshwater needs for generations to come.

The surface water supply for West Palm Beach, Palm Beach, and South Palm Beach is derived from annual rainfall captured and stored within the 27 square mile wetland system of Grassy Waters Preserve.  This historical Everglades ecosystem feeds and maintains the twin lake reservoirs of Lake Mangonia and Clear Lake and encompasses nearly 50% of the City of West Palm Beach.

The Department of Public Utilities Watershed Management Division is dedicated to protect, preserve, and restore the ecological integrity of Grassy Waters Preserve by preventing the proliferation of invasive species, promoting best management practices in water quality and conservation, and educating the public about the importance of this ecosystem.  The Watershed Management Division carries out the daily task of providing operational maintenance to pump stations and control structures throughout the watershed while performing water quality and compliance monitoring to ensure the long-term health of the City’s water supply.

Environmental Education staff support the mission of the Watershed Management Division by providing hands-on educational experiences at Grassy Waters Preserve for learners of all ages.  Access to this historic wetland reconnects visitors with the natural heritage of West Palm Beach.  Trails of varying lengths and difficulties are accessible to the public for no charge.  Experienced naturalists also provide guided canoe and hiking programs for the public, merit badge programs for scouts, and free field trips for local schools.
