The South Texas Weather Modification Association (STWMA) is a non-profit organization
consisting of several water districts committed to enhancing rainfall across the south Texas
operation area. Rainfall enhancement is conducted using cloud seeding techniques where
aircraft release microscopic particles of silver iodide and calcium chloride into thunderstorms to
increase rainfall efficiency.
The association first formed in 1996 and conducted its first cloud seeding mission the following
year. After 20 years in existence, the STWMA, based in Pleasanton, continues to perform
seeding operations over multiple counties in south-central Texas.
