PURPOSE AND EFFECT: The purpose and effect of the proposed rule amendment will be to adopt minimum flows and levels for the St. Johns River at State Road 50, in Orange and Brevard Counties.
SUBJECT AREA TO BE ADDRESSED: The proposed rule would establish minimum surface water flows and levels for the St. Johns River at State Road 50 in Orange and Volusia Counties pursuant to the mandate of Section 373.042, Florida Statutes. Each of these flows and levels would have an associated duration (in days) and return interval (in years). The terms used herein are already defined in Chapter 40C-8, F.A.C.
