Depositional and structural history control regional trends in transmissivity and hydraulic conductivity in Lower Cretaceous‐age sandstones along the Balcones‐Ouachita trend in north‐central Texas. Because of a scarcity of pumping tests, delineation of trends was possible only by incorporating transmissivities estimated from specific capacities. Statistical comparison of estimated and pumping‐test transmissivities confirmed the validity of this approach. The resulting contour maps should be useful in evaluating these aquifers as potential low‐temperature geothermal resources. The method can also be applied to other aquifers to facilitate ground‐water management programs.
