A generalized finite-difference model was prepared for the Blaine aquifer in southwestern Oklahoma and northwestern Texas. This report releases the model for use and modification. A grid of 1-square-mile nodes was established over the area, with 1,030 of the nodes actively simulated in the model. The steady-state model simulation used a uniform recharge rate of 2.2 inches per year and three values of hydraulic conductivity: 80, 19, and 4.7 feet per day. About 44 percent of the recharge is discharged as pumpage from wells, and the remainder is discharged to rivers and creeks within and adjacent to the study area.
