Water is the most important limiting factor to agricultural production and economic growth in the Southern High Plains of Texas. The use of groundwater from the Ogallala Formation has helped to remove these water limitations but the remaining water in the Ogallala Aquifer is rapidly being depleted. Research was concentrated on the removal of sedimentation as a restriction to artificial recharge. Gravity flow recharge wells appear to be an effective means of recharge. As particle size of the aquifer decreases, increasing attention was given to the possible effects of the introduction of foreign materials into the formation. Other groundwater recharge methods discussed are filtration systems, trenches, shafts, and shallow holes. (Author)
