Watershed Assessment


News & Announcements

New! The Department announces the availability of the 2016 Strategic Monitoring Plans. These plans represent the water quality and biological monitoring being done by the Department in preparation for basin assessments as part of the watershed management approach.

The Watershed Assessment program has developed the 2016 Strategic Monitoring Plans to assist in assessing the health of surface waters by conducting hydrological and biological watershed-based monitoring activities. These activities are carried out by seven Regional Operation Center (ROC) offices located throughout the Department’s six District offices and by staff in Tallahassee.  This extensive monitoring effort is accomplished through strong coordination with water management districts, city and county governments.  

New! Draft Lists of Assessments in the Group 3 (Cycle 3) Basins for the Verified List of Impaired Waters, Delist, Study, and Natural Background Lists  

The Department announces the availability of the DRAFT lists of assessments for waterbodies and water segments within the Group 3 Basins: Caloosahatchee, Choctawhatchee – St. Andrews, Lake Worth Lagoon – Palm Beach Coast, Sarasota Bay – Peace Myakka, and Upper St. Johns. These lists will be presented at a series of public meetings in January and February.

 REVISED Lists of Assessments in the Group 2 (Cycle 3) Basins for the Verified List of Impaired Waters, Delist, and Study Lists

The Department announces the  availability (08/24/15) of the REVISED lists of assessments for waterbodies and water segments within the Group 2 Basins: Apalachicola-Chipola River, Charlotte Harbor, Lower St. Johns River, Middle St. Johns River, St. Lucie – Loxahatchee, and Tampa Bay Tributaries.

The Department Announces the 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.

The Department is pleased to announce the publication of the 2014 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 government, universities, volunteer groups, and individuals – resulting in substantially more monitoring statio

ns and water quality data than any other state in the nation. More than 30% of the nutrient data for the nation comes from Florida waters. In fact, 25% of the nation’s ambient water quality monitoring stations (more than 41,000) are located within Florida.

This large amount of water quality data is used annually for the assessment of waterbody health by means of a comprehensive stepwise approach. Hundreds of assessments are conducted each year. Additionally, as part of this report, a statewide water quality condition is presented using an unbiased randomized monitoring design, and water quality trends are reported at 76 separate surface water and 49 ground water stations. These efforts allow us to understand the state’s water conditions, make decisions that further enhance our waterways, and focus our efforts towards to address 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.

DEP'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.
