Impaired Waters Listing Process

The core function of the Watershed Assessment Section is to use the best available information to identify waterbodies and water segments (WBIDs) that are not meeting the applicable water quality standards and designated uses based on the Impaired Waters Rule Chapters 62-303 and 62-302, Florida Administrative Code (F.A.C.).

How often are WBIDs assessed?

DEP’s watershed management approach is an established five-year cycle that rotates through 29 basins throughout the state over a five-year period (all WBIDs will be assessed once every five years).

Statewide Alternative Restoration Plan Status

DEP works statewide to encourage local stakeholders to develop Alternative Restoration Plans (4b or 4e plans) at the earliest practical time. Early implementation of restoration activities is more cost effective and may allow DEP to forgo certain regulatory steps - most notably, the development of Total Maximum Loads (TMDLs) and Basin Management Action Plans (BMAPs) - thereby focusing limited local and state resources directly on measures that will improve water quality.

Statewide Biological Database

The DEP Laboratory administers the Statewide Biological Database (SBIO). The SBIO database was developed in the early 1990's in response to the need for centralization of biological data collected by DEP and its predecessor agencies.
