RE: Permit #72-110 Florida Power and Light
1. Approve the permit with the following restrictions or conditions to be complied with.
A. Limit diversion to periods when flow is above 30 cfs during any month.
B. Install a staff and recording gage at the diversion site.
C. Determine the elevation at which a corresponding flow of 30 cfs will be
D. Develop an alternate partial make-up source of water supply.
E. All waste water is to be disposed of within the reservoir.
F. Material collected from trash screens is to be disposed of upon upland
2. Explanation of 1. A. -- diversion limit of 30 cfs.
Chapter 373 authorizes the capture of water above the minimum average flow.
It does not require that all excess flow, or any excess flow, be authorized.
The decision to recommend restriction on pumping to above 30 cfs at this time
is an arbitrary one, based only upon a feeling that it would be detrimental for the
downstream reach to be constantly kept at the average minimum flow, particularly
when by definition, the average minimum flow is the average of the 5 lowest
monthly mean discharge over a 20 year period and represents flow during extreme
Studies could be made to support the proposal to limit diversion or determine if
some other more or less restrictive diversion rate is warranted.
