Specifications

Specifications include, but are not limited to: Per statute, the Texas Water Development Board (TWDB) is tasked with developingnumerical groundwater flow models of the major and minor aquifers in Texas. TheCross Timbers Aquifer was designated as a new minor aquifer in December 2017.The aquifer consists of four Paleozoic-age water-bearing formations including, fromoldest to youngest, the Strawn, Canyon, Cisco, and Wichita groups. The aquifer isprimarily composed of limestones, shales, and sandstones. This project will compileand analyze data related to climate, geology, hydrostratigraphy, water levels, crossformationalflows, aquifer recharge, surface water features, hydraulic properties,natural and man-made discharge, and water quality in the study area. Specifically,this project will also collect, analyze, and interpret available data related to the CrossTimbers Aquifer including possible flows between the overlying Trinity and Seymouraquifers and underlying geologic units, and flows between the Paleozoic units thatcomprise the aquifer. The project will also investigate and recommend anappropriate boundary for the future model. We have tentatively set the study areafrom where the Strawn Formation meets the Ouachita Fold Belt to the east, thesouthern Oklahoma Aulacogen (Fault Zone) to the north, the eastern edge of theBlaine Aquifer to the west, and where the Permian units are truncated by the LlanoUplift Area to the south. In addition, data analysis will include predevelopment to atleast 2015 or more recent times. This project will develop the conceptual model thatwill later be used to develop a groundwater availability model of the aquifer.
