Surface Water Improvement and Management (SWIM) Plans


The SWIM Act was enacted in 1987 and designated the Lower St. Johns River Basin as a SWIM waterbody based on its water quality.  The SWIM Plan for the basin was initially developed in 1989 was updated in 1993.   The St. Johns River Water Management District (SJRWMD), in conjunction with basin stakeholders, updated the plan in 2008, which describes the management issues related to water quality, biological health, toxic contaminants, public education, and intergovernmental coordination and a 5-year list of projects to address these management issues.  The updated plan also includes the Lake George basin and designates this basin as a SWIM waterbody. 


Basin Management Action Plan (BMAP) Documents

BMAPs outline projects, programs, and management actions to address the nutrient Total Maximum Daily Loads (TMDLs).  Once adopted by the Secretary of the Department of Environmental Protection, the reduction requirements outlined in the document are binding and may be linked to related national pollutant discharge elimination system (NPDES) permits.
These BMAP documents are available on the FDEP website at:

The Lower St. Johns River Main Stem Nutrients BMAP (2008)

This BMAP is the implementation plan for nutrient TMDLs for both the marine and freshwater sections of the main stem of the river.  The BMAP was developed by the Florida Department of Environmental Protection (FDEP), St. Johns River Water Management District (SJRWMD), and basin stakeholders.  Follow the link to view the final version of the Lower St Johns River BMAP on the FDEP website:

Lower St. Johns River Initiative Documents
The Lower St Johns River Initiative is a funding effort led by St. Johns River Water Management District (SJRWMD) to obtain state funding to implement projects to improve water quality and protect surface water resources.  These projects include reuse, wastewater facility upgrades, stormwater management, and agricultural best management practices (BMPs).   A list of the initiative documents can be found on the TAC Legislative Initiatives page:

The State of the River Report

The State of the River Report was put together by a team of academic researchers from Jacksonville University and the University of North Florida and funded by the City of Jacksonville Environmental Protection Board (EPB). The purpose of the State of the River Report was to pull together data and literature pertaining to the conditions in the river that had been previously collected and present it in an easily assessable format. Data from several different sources were examined, including data from the Florida Department of Environmental Protection, St. Johns River Water Management District, Fish and Wildlife Commission, City of Jacksonville, individual researchers, and others.

St. Johns River Water Supply Impact Study - FINAL REPORT

The St. Johns River Water Supply Impact Study, the most comprehensive and scientifically rigorous analysis of the St. Johns River ever conducted, was completed and presented to the St. Johns River Water Management District's Governing Board on Feb. 14, 2012.

The four-year study resulted in the development of tools that will help guide future decision-making on the potential environmental effects of proposed water withdrawals from the St. Johns and Ocklawaha rivers on the St. Johns River system.  The state-of-the-art models and methodologies that resulted from the study will be used in consumptive use permitting, minimum flows and levels development, regional water projects and water supply planning.

Jacksonville Harbor Deepening Study

The District conducted a study to increase the depth of the existing federal channel along the St. Johns River from its current project depth of 40-feet to a maximum depth of 47-feet.  The extent of this deepening would occur from the mouth of the St. Johns River to approximately River Mile 13.  Please see the Jacksonville Port Authority website for additional information on the status of the harbor deepening project:
