New! Draft List of Assessments in the Group 5 Basins for the Verified List of Impaired Waters, Delist, Study, Study List Removals, and Natural Background Lists

The department announces the availability of the DRAFT lists of assessments for waterbodies and water segments within the Group 5 Basins: Everglades, Florida Keys, Indian River Lagoon, Perdido, Spring Coast, and Upper East Coast. These DRAFT Verified Lists, Delist Lists, Natural Background Lists, and Study Lists were produced with water quality and biological data included in the IWR Database Run 53. These lists reflect the department’s current assessments for these waterbodies, but they are subject to change based on input received during the public comment period, which ends November 1st 2017. (extension of review time due to impacts of Hurricane Irma)

FINAL List of Assessments in the Group 4 Basins for the Verified List of Impaired Waters, Delist List, and Study List

The department announces the availability of the FINAL lists of assessments for waterbodies and water segments within the Group 4 Basins: Fisheating Creek, Kissimmee, Nassau – St. Marys, Pensacola Bay, Southeast Coast – Biscayne Bay, and Withlacoochee.  These FINAL Verified Lists and Delist Lists were adopted by a Secretarial Order signed by DEP Secretary Noah Valenstein, on June 27, 2017.  This Order also includes amendments to the Verified List of Impaired Waters for two waterbodies, one in the Group 2 Tampa Bay Tributaries basin, and one in the Group 3 Lake Worth Lagoon – Palm Beach Coast basin. The department will be submitting to EPA these final assessments, as well as the Group 4 Study List additions and removals as updates to the federal 303(d) list.

Submitting Bioassessment Data

The department is requesting external data providers who would like to submit applicable bioassessment data to help support the department's Impaired Waters assessment. Please download and complete the Bioassessment Data Template, available as a Microsoft Excel worksheet (.xlsx). Once the template has been completed with the required information, please submit the worksheet and all supporting documentation (field sheets, LVI calculations, photos, etc.) by email to Kevin O'Donnell.

Guidance on Developing Restoration Plans as Alternatives to TMDLs

The department encourages stakeholders (including state agencies and local governments) to seek 4b assessments or 4e assessments by submitting documentation in support of assessment category 4b or 4e. For this designation, documentation will be required to demonstrate reasonable progress that the proposed projects or programs will restore an impaired waterbody.

Blue Springs Run near the confluence with the St. Johns RiverDEP's Divisions of Water Resource Management and Environmental Assessment and Restoration implement a wide range of programs to protect and restore Florida's surface waters. Tour this website and you will find dozens of different strategies and activities underway to benefit water quality. At the heart of these efforts, particularly in identifying water quality problems and establishing clean-up objectives, is the Watershed Assessment program.

2016 Integrated Water Quality Assessment for Florida 

The Department is pleased to announce the publication of the 2016 Integrated Water Quality Assessment Report for Florida. This report represents one of the most comprehensive data collection efforts in the nation and provides the reader with substantial information regarding the quality of our waters. These comprehensive analyses are made possible by the support of the citizens of Florida, who agree that our waterbodies are a central part of our state’s culture and heritage. This report includes contributions from monitoring efforts at all levels – by state and local government, universities, and volunteer groups.

Florida has substantially more monitoring stations and water quality data than any other state in the nation. This amount of water quality data is used annually for the assessment of waterbody health by means of a comprehensive approach. Hundreds of assessments of individual waterbodies are conducted each year. Additionally, as part of this report, a statewide water quality condition is presented using an unbiased random monitoring design. These efforts allow us to understand the state’s water conditions, make decisions that further enhance our waterways, and focuses our efforts on addressing problems. (Excerpted from the Letter to Floridians.)

Florida’s rivers, streams, lakes, estuaries, and coastal waters are spectacularly beautiful. More than that, they are essential natural resources, supplying the water necessary for aquatic life, both large and microscopic; drinking water; recreation; industry; fishing and shellfish harvesting; and agriculture. Florida's multi-billion tourist industry would vanish if our water resources were irreparably degraded.

Protecting these abundant water resource, restoring them when they become damaged because of unmanaged growth and development, and preserving them for the future is your responsibility and ours.
