Recorded rainfall data for Texas goes back to 1895. And that is State Data. Texas is a very big state. And rainfall varies greatly.
My family arrived in Haskell County in 1889. There was a very bad drought in 1895 that cause some of the family to leave for 3 years and go back to near Austin. This year may have actually been worse than the 1895 drought. But remember weather is very local.
