The estimated total well and spring discharge from the Edwards and associated limestones in the San Antonio area during 1971 was 679,500 acre-feet, or about seven percent less than 1970. The total discharge was 26 percent greater than the average for 1934-70.

About 60 percent of the total discharge came from wells, and approximately two-thirds of this discharge was from wells in Bexar County. Well discharge in 1971 was 24 percent greater than in 1970, while springflow decreased by about 30 percent.

Deficient rainfall during the spring and early summer of 1971 was mainly responsible for the increased demand for water from wells and the decrease in the discharge of the springs.
