Lucie Estuary and reduce sediment and nutrient loads to benefit 2,740 acres of estuarine habitat.
IFP Start Date: 1997
IFP Completion Date: TBD
2009 IFP Cost: $50M ($43.9M appropriated thru FY2009)
Status: The in-lake portion of dredging was completed by spring of 2006. The second phase of construction and muck removal should have been completed by December 2007, but dredging was delayed due to dry weather and low water. The uncompleted second phase was re-initiated in the spring of 2009 as Phase III, and included dredging the uncompleted littoral zones and deeper portions of the lake. This work is expected to be complete in the first quarter of 2011. The containment facility and much of the dredging have been completed as of early 2008.
Observed and Projected Benefits: Approximately 3 million cubic yards of organic sediments that blanketed the bottom of the lake were removed. Expectations include improving water quality, reestablishing native vegetation, and improving subsequent flows to Corkscrew Swamp Sanctuary and the Florida Panther National Wildlife Refuge. Lake monitoring by the local university has identified significant improvement in the quality of the lake from Phase I and Phase II dredging.
