First Irrigation Well In Lamb County Dug by hand in 1902 for crops, cattle, and household use of Ewing Halsell (1877-1965), son of land promoter and settler W. E. Halsell, an irrigation ditch carried water half a mile to headquarters of Halsell's "Mashed O" Ranch. Six feet in diameter but only 30 feet deep, well is no longer in operation.
