Minimum Flows and Levels for the Crystal River/Kings Bay System

The District establishes Minimum Flows and Levels (MFLs) to help protect water resources. An MFL is a regulation to protect springs, spring runs, rivers, lakes, wetlands and aquifers from ground and surface water withdrawals that would cause significant harm.


Minimum flows and levels are limits established by the District Governing Board for surface waters and groundwater that are intended to prevent significant harm to the water resources or ecology of an area that may be caused by water withdrawals. Field survey Proposed minimum flows for the Crystal River/Kings Bay System in Citrus County are summarized in a revised final draft report and appendices (App. 1, App. 2, App. 3 and App. 4).

In accordance with Section 373.0421(4), Florida Statutes, the District voluntarily subjected all scientific or technical data, methodologies, models, and scientific and technical assumptions used to support development of the proposed minimum flows to independent scientific peer review. The Crystal River/Kings Bay System’s review was conducted by a panel of three independent, recognized experts in the fields of hydrology, hydrogeology, limnology, biology and other scientific disciplines relevant to the development of the minimum flows. The panel prepared a final report for the District Governing Board and the Board gives significant weight to the report when establishing the minimum flows for the Crystal River/Kings Bay System.

Peer Review Panel Meetings

Meetings conducted by the peer review panel occurred in November and December 2016. They included an initial, in-person meeting, which included a field trip to sites on the bay and river, as well as web-based teleconferences facilitated from the District’s Brooksville office. Details about the peer review panel’s work is accessible through the Web Forum.
