Econfina River Minimum Flows & Levels
About the Econfina River
The Econfina River is a black water river that begins in Madison County and flows for approximately 40 miles through Taylor County, where it then discharges into the Gulf of Mexico. The river picks up tannins from decaying vegetation and acquires a black tint as it flows south. There are no major springs that feed the Econfina River as it flows through swampy lowlands.
River Minimum Flows & Levels
The District's Minimum Flows and Levels (MFLs) program is a means to ensure water availability for the present and future, and to prevent "significant harm" to the area's natural resources. The Florida Legislature has directed the five water management districts to establish MFLs for streams, springs, rivers, lakes and other priority water bodies. In accordance with the District's priority MFL schedule (PDF), work has been completed on the draft MFL for the Econfina River, which is scheduled to be finalized by the end of 2015. As defined by statute (Section 373.042 Florida Statutes), "the minimum flow for a given watercourse shall be the limit at which further withdrawals would be significantly harmful to the water resources or ecology of the area."
The District has an accelerated schedule to establish MFLs for its priority water bodies. The District's MFL Program is a science-based process, which the District Governing Board uses to establish MFLs. This process uses the best information available to determine recommended MFLs. Before adoption by the Governing Board in the District rules, the science supporting the MFLs is subject to a peer review process initiated by the District.
The District voluntarily submits to independent scientific peer review for all MFLs established. This practice ensures that the highest degree of scientific certainty is provided prior to adopting a MFL by rule.
