A Review of the Edwards Aquifer Precipitation Enhancement Program
AbstractThe organization and facilities of the Edwards Aquifer Precipitation Enhancement Project (EAPEP) is reviewed, and the resources applied in the 1999, 2000, and 2001 seasons are summarized. A preliminary evaluation of the 1999 and 2000 project seasons suggests a 24% increase in rainfall volume for floating target units of 1,964 km^2 that actually received treatment within the Edwards Aquifer fixed target. This corresponds to an average water increment of 626 acre-feet per unit. The full effect of seeding over the entire target area is presently unknown. The current estimate of the benefit-to-cost ratio is 9:1.
