The Indian River Lagoon (IRL) was designated in the 1987 Surface Water Improvement and Management (SWIM) Act as a priority water body in need of restoration and special protection. Major problems leading to this designation included the loss or alteration of 75 percent of the lagoon’s salt marsh and mangrove wetlands, excessive freshwater discharges into the central lagoon due to drainage improvements in coastal watersheds and diversion of floodwaters from the St. Johns River floodplain, and discharges of pollutant-laden wastewater and storm water into the lagoon. Excessive freshwater degraded shellfish habitat, and pollutants in discharges exacerbated the turbidity (cloudiness of the water) and promoted algae growth, contributing to the destruction of seagrass beds. In 1991, the IRL became a part of the National Estuary Program (NEP). Efforts under the IRL program at the St. Johns River Water Management District focus on improving water and sediment quality to restore or enhance sea grass and on rehabilitating impacted wetlands to recover as many of their natural functions as possible.
