Infiltration from controlled canals minimizes the depth and extent of the cone of depression about the well fields in the Miami Springs-Hialeah area and prevents sea-water intrusion. In the 1940's the controlled canals contributed 78 to 100 percent of the dry-season pumpage. Average pumpage has increased from 67 to 92 million gallons per day during 1961-71 without significantly affecting the quality of well-field water. Water demands since 1961 have caused the cone ofdepression to expand beyond the limits of the recharging canals; therefore, the percentage of dry-season contribution from the canals has decreased. In April 1971, the cone of depression expanded southward and caused deep salty ground water in the vicinity of the Tamiami Canal to move northward beneath the airport toward the well fields, forcing a reduction in pumpage. A temporary dam was installed in the Tamiami Canal in September 1971 as a stopgap measure to minimize the threat of sea-water intrusion.
