Water bodies, watersheds and storm water

Middle St. Johns River Basin

The Middle St. Johns River Basin in central Florida is a highly urbanized area that encompasses the water­sheds of five major sources to the St. Johns River, extending more than 1,200 square miles. Each of the watersheds is unique and has characteristics that require variable and adaptive approaches when addressing water resource issues. Among the region’s challenges is how to restore degraded lakes and streams, and to help people understand that their everyday activities have a cause-and-effect relationship on the St. Johns River and the other area waterways.

Solutions

Location of Middle St. Johns River Basin

The St. Johns River Water Management District works to preserve those areas of the middle basin still in good condition and restore those areas that have degraded over the years. The district’s ongoing work includes monitoring, modeling, diagnostics and analysis and implementation of selected environmental restoration projects, such as the Econlock­hatchee Phosphorus Reduction Project and the Palm Bluff-Maytown Phosphorus Reduction Project. Both projects include contaminant and ecological surveys, as well as assessments to determine the best methods for removing phosphorus from waterways. Gathered information will be used to design facilities needed to extract phosphorus from these water bodies.

A Surface Water Improvement and Management (SWIM) plan serves as a guide to the work that the district and its partners are doing in the basin, including building stormwater retrofit systems and developing pollutant load reduction goals (PLRGs) that will provide an estimate of reduction in pollutants needed to preserve or restore the waterway.

The accomplishments include:

  • Expanding water quality modeling, diagnostics and compliance
  • Developing total maximum daily loads (TMDLs), pollutant load reduction goals (PLRGs) and basin management action plans (BMAPs) to address water quality impairments
  • Prioritizing stormwater retrofit programs for older developments
  • Targeting areas with the highest nutrient loads
  • Seeking funding to implement or assisting local governments to implement stormwater master plans
  • Implementing erosion control projects and various water quality improvements throughout the basin
  • Developing plans for subbasins that address the specific needs of the watershed
  • Investigating land development rule changes to improve watershed protection
  • Addressing flooding
  • Preserving environmentally sensitive land
