Ground water in the Grand (Neosho) River basin, Kansas and Oklahoma

Ground water in the Grand (Neosho) River basin occurs in both consolidated rocks and unconsolidated deposits. Water for domestic and stock supplies generally can be obtained from wells in either of the above deposits. Water for municipal, industrial, and irrigation supplies generally can be obtained in limited quantities from the unconsolidated deposits of sand and gravel and in adequate quantities from the consolidated rocks in the southeastern part of the area.

The unconsolidated deposits in the basin receive about 226,000 acre- feet of recharge annually, and about 775,000 acre-feet of water is in storage in the deposits. An additional 77 million acre-feet is in storage in the consolidated aquifers. In 1968 about 7,500 acre-feet of ground water was withdrawn for all purposes. About 6,300 acre-feet of surface water and 1,400 acre-feet of ground water was withdrawn for irrigation of 7,600 acres of cropland. The total annual ground-water withdrawal for irrigation may be as much as 20,000 acre-feet by year 2000.
