INTRODUCTION
Well yield is an important apet in designing ground water supply
system and planning for watersupplydevelopment. The number and size




mmute per we can be obtained. This map report depicts the great





streams, or the flow of salt water or contaminants toward wells. Some areas
shown on the map may yield much le water than that amount shown, and
- others much m ben use of variation in aquifer characteristics

composed chiefly of limestone and dolomite. In me places the Floridan
