The estimated total well and spring discharge from the Edwards and associated limestones in the San Antonio area during 1972 was 747,100 acre-feet, which is the record high for the period 1934-72. The increase was due primarily to above-average springflow.

The total discharge from wells and springs for 1972 was about 10 percent more than in 1971, and 38 percent greater than the average for 1934-71.

About 50 percent of the total discharge came from wells, and approximately two-thirds of this discharge was from wells in Bexar County. Well discharge in 1972 was 10 percent less than in 1971, while springflow increased by about 37 percent.
