Usually, it's to end a drought.
However, I am inclined to believe that they do this to try and psyop Texans and the rest of the country into believing that there is a "climate crisis" so that they can make the case for implementing climate change mitigation policies that really have nothing to do with climate and more to do with controlling the population.
