Summary

2008 marked the seventh year of operations for the Edwards Aquifer Authority (EAA) by the Southwest Texas Rain Enhancement Association (SWTREA). The project this year was business as usual, with seeding taking place in Uvalde County from May until September. … Most of South Texas and the counties within the Aquifer saw a very dry year in 2008.

Seeding in the Authority target area of Uvalde County saw a total of five flights for the 2008 operational year, two of which were reconnaissance flights….

2008 was the second year of a three year randomized seeding experiment. The randomized seeding experiment was also conducted by the EAA’s other weather modification contractor, the South Texas Weather Modification Associationi(STWMA). The objective of randomized seeding operations for the Edwards Aquifer Authority was to select clouds that met the criteria for suitable seeding candidates. This was seeding at random, and from that point, measurements and observations were taken to determine if seeding had an effect on the cloud. The experiment was double blind so that ground operations staff would not know which clouds were seeded and which were not seeded due to bias that could occur. …

At the September 30th conclusion of the 2008 operational season for the EAA target area, a radar evaluation was completed for the program. The findings arc presented and discussed towards the end of this report. The flight logs for the 2008 seeding season are listed…
