REPORT OF INVESTIGATIONS No. 41 Figure 17. Map of the Panama City area showing the location of water wells for each water system and the area supplied by these systems. in early 1964. In January 1964 one well field consisting of 21 wells was shut down. The water levels in this well field recovered 163 feet within 51 days. Figure 18 shows the approximate piezometric surface in 1908 under natural water conditions. The piezometric surface in 1962 (fig. 13) shows the lowered water levels caused by pumping since 1908. HISTORY OF GROUND-WATER DEVELOPMENT The first deep well reported in the Econfina Creek basin was completed in 1908 for an ice plant in downtown Panama City (Sellards, 1912). In 1909 Panama City drilled a city supply well at the location of the old National Guard Armory. In the same year. another well was drilled near. the 'present water tank on Eleventh Street to supply St. Andrew.
