2022-2024 Biennial Assessment Draft Verified and Delist Lists

DRAFT 2022-2024 Biennial Assessment Verified and Delist Lists

(October 2, 2023)

The Department announces the 2022-2024 Biennial Assessment Draft lists of waterbodies and water segments. The DRAFT assessment lists were developed pursuant to Chapter 62-303, Florida Administrative Code (F.A.C.), and include all 29 basins in the state. The Draft Verified Lists include those waters that are proposed as additions to the State's Verified List of Impaired Waters and the Clean Water Act (CWA) section 303(d) list. The Draft Delist Lists include those waters that are proposed for removal from the State's Verified List and CWA section 303(d) list. The department has posted the draft Master Lists (which contain all assessments for all waterbodies in each basin) here

In addition to the draft assessment lists in spreadsheet format, the department has published an interactive map titled "Biennial Assessment 2022-2024 Draft 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. For help using the interactive map features, please review this help file, or alternatively you may download the draft list GIS shapefiles as a geodatabase

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 include station-WBID assignment updates, WBID classification updates and/or data that have been excluded from assessments based on a preliminary evaluation by department staff.

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