Cross Timbers Aquifer

The Cross Timbers Aquifer was designated as a minor aquifer by the Texas Water Development Board in 2017. While the Cross Timbers Aquifer is the new kid on the block, it is actually much older than the major Seymour Aquifer that was discussed above. The Seymour Aquifer is about a million years old while the Cross Timbers Aquifer materials are about 300 million years old.

The portion of the Cross Timbers Aquifer that occurs within the District is derived from porous sandstone and limestone beds of the Wichita Group (Lower Permian) that occur in the eastern third of Baylor and Haskell counties. Small to moderate amounts of fresh to slightly saline water can be produced from the Cross Timbers with typical well yields ranging from one to twenty gallons per minute.

Within the District, water produced from the Cross Timbers is almost exclusively used for livestock. In the past, some domestic use occurred but most domestic use today is provided by retail water providers that source their water from the Seymour Aquifer or from surface water sources.
