Abstract
Water levels have declined in the southern part of the High Plains aquifer of the
central USA since the mid-1960s in response to extensive irrigation
development. The North Canadian River originates in western Oklahoma, and
most of the basin is underlain by the High Plains aquifer. Average river flow in
the headwaters near Guymon, Oklahoma, has decreased from about 0.9 nrVs
before 1970 to near zero at present. Canton Lake, on the North Canadian River
near Selling, about 250 km downstream from Guymon, is a source of water
supply for Oklahoma City. Precipitation data and streamflow data for gages
upstream from Canton Lake were divided into an "early" period ending in 1971
and a "recent" period that begins in 1978. The early period represents conditions
before ground-water levels had declined appreciabl
