REPORT OF INVESTIGATIONs No. 41


posed a plan to divert water from Econfina Creek to a group of lakes known as The Deadening (see p. 73) and thereby stabilize their levels. This plan, if executed, would add about 4,000 acres to the normal size of this group of lakes.

                           AQUIFERS
   The three aquifers - the water-table aquifer, the secondary artesian aquifer, and the Floridan aquifer - store large quantities of water. The portion of rainfall that enters these aquifers through downward percolation is stored temporarily.
   Water contained in the water-table aquifer discharges slowly by downward percolation to the underlying aquifers and to the streams and lakes through seepage and small springs. The water-table aquifer, in the basin, is composed of fine to coarse sand and contains a volume of water approximately one-fourth the volume of the saturated section. The fluctuation of water levels in the water-table aquifer is an indication of the change in storage, shown in figure 10. During dry periods the water levels decline as the aquifer discharges the water from storage. In wet periods water levels rise as more water is received by the aquifer than is discharged.
   Exclusive of flow from the artesian aquifer, the low flows of the streams are maintained by seepage from the water-table aquifer and
