FINAL Biennial Assessment 2022-2024 Verified and Delist Lists

(August 19, 2024)

The department announces the Biennial Assessment 2022-2024 final assessment lists of waterbodies and water segments. The FINAL assessment lists were developed pursuant to Chapter 62-303, Florida Administrative Code (F.A.C.), to include all 29 basins in the state and were adopted by Secretarial Order. The Final Verified Lists include those waters that have been determined to not meet water quality standards and are additions to the State's Verified List of Impaired Waters and are proposed for addition to the Clean Water Act (CWA) section 303(d) list. The Final Delist Lists include those waters that are removals from the State's Verified List and proposed for removal from the CWA section 303(d) list for several reasons such as the waterbody is no longer impaired, a TMDL has been completed, the parameter verified impaired in the previous assessment was due to a flaw in the original analysis, or corrections made to the waterbody type or class.  Waterbodies identified on the Final Verified List will be scheduled for a TMDL following the Prioritization Framework for TMDL Development. A TMDL represents the maximum amount of pollutant loading that can be discharged to a waterbody and have its designated uses be met.

In addition to the final assessment lists in spreadsheet format, an interactive map titled "Biennial Assessment 2022-2024 Final Lists" that shows the geographic location of the waterbodies and waterbody segments by WBID that are proposed for addition to the Verified List, Delist List, Study List, or Study List Removals. These assessment lists were produced with water quality and biological data included in the IWR Run 64 Database that has been received by the department as of July 13, 2022. They also incorporate station-WBID assignment updates, WBID classification updates and/or data exclusions based on a preliminary evaluation by department staff.

For best results, print on legal size paper (8.5 x 14).
