Division:

St. Johns River Water Management District

Chapter:

MINIMUM FLOWS AND LEVELS

Overview

RULE:

40C-8.031

Minimum Surface Water Levels and Flows and Groundwater Levels

PURPOSE:

The purpose and effect of the proposed rule amendment will be to establish minimum surface water levels for Johns Lake in Lake and Orange counties and to clarify the location of Lakes Brooklyn and Geneva in Bradford and Clay counties. These minimum water levels, if adopted by rule, will represent the limit at which further withdrawals would be significantly harmful to the water resources of the area or ecology of the area. The proposed minimum water levels for Johns Lake will not be in prevention or recovery. Thus, they will not have an adverse impact on small businesses or increase regulatory costs.

SUBJECT:

The proposed rule would establish minimum surface water levels for Johns Lake pursuant to the mandate of Section 373.042, Florida Statutes, and clarify the location of Lakes Brooklyn and Geneva. The terms used herein are already defined in Chapter 40C-8, F.A.C. As with all minimum surface water levels established by the District, if adopted, the minimum surface water levels in this rule amendment would be used as a basis for imposing limitations on withdrawals of groundwater and surface water in the consumptive use permit regulatory process and for reviewing proposed surface water management systems in the environmental resource permit regulatory process.
