South Texas Weather Modification Association is a non-profit organization consisting of several water districts and a county commissioner's court. The association first formed in 1996 and conducted its first seeding mission the following year. After a decade of existence, the STWMA, based in Pleasanton, continues to perform seeding operations over multiple counties in south-central Texas. A map of the project area can be found here
