(During the time that the desalination plant has been in operation, questions have been raised by water- management agencies concerning the ability of the deep artesian aquifers underlying Sanibel and Captiva Islands to continue supplying the water needed to meet the increasing demand with a salinity low enough for the desalination plant to operate effectively.  The purpose of this investigation was to evaluate the water- supply potential of the deeper aquifers.  During the 24-month investigation (October 1975-1977) an important objective was to locate and inventory all existing wells that tapped the deep artesian aquifers.  Except for a few, all known wells were found.  Water levels and water samples were obtained at the wells.  No test wells were drilled as part of this investigation, although one observation well was drilled on Sanibel Island as part of a countywide monitoring network.)

(This report presents the results of a study designed to measure and describe flow in selected areas of Tampa Bay and Charlotte Harbor.  A total of 232 measurements of flow were made at the mouth of each estuary and within Anna Maria and Pine Island Sounds.  Data collection included measuring the flows into (flood) and out of (ebb) each estuary and sound under a range of tidal elevation, wind, and freshwater inflow conditions.  Measurements of tidal elevation (water-surface elevation) and wind magnitude and direction were made while flow data were being collected.  Freshwater inflow data from established U. S. Geological Survey gagging sites were used to quantify freshwater inflow.)
