Reading comes from Texas Water Development Board — Water Data for Texas (Water Data for Texas — pat-mayse) by way of our own server, which asks the agency each time you load this page and passes on its figure in the agency's own datum, unchanged. Water Data for Texas publishes one figure a day for each reservoir, so the date beside the reading is the day that figure covers. For everything else the agency publishes about this reservoir, go to Pat Mayse Lake at Water Data for Texas.
