Large well‐field developments in the Mid‐Gulf area have caused abnormal lowering of nearby lakes. A map showing the differential head between the surficial aquifer and the underlying limestone Floridan aquifer showed values ranging from 20 feet to zero at a location where the aquiclude is absent. Lake levels had been restored by pumping from limestone wells. From pumping data and analysis of recession limbs, lineal relations between recession rates and differential head appeared to exist. From these, leakance values and vertical permeabilities were determined, with the latter values for two distinctly different sites ranging from 2 × 10 ‐2 to 200 gpd/sf.
