Title:
St. Johns River Water Supply Impact Study

The four-year study has tremendously advanced the science of the river, providing a body of advanced science and engineering knowledge, methodologies and analyses to evaluate future permit applications seeking water withdrawals from the river. The impact study does not authorize water withdrawals, nor does it set an absolute amount of water that can or will be withdrawn from the St. Johns River. The study was peer reviewed by the National Academy of Sciences — National Resource Council.
