Marilyn E. Pabst 1977 <p>This report contains basic data on water-level measurements in observation wells in western Kansas. Most of the measurements were made in January 1977; a few were made in December 1976 and in February 1977. The measurements were made in mid-winter when pumping was minimal and water levels had recovered from the effects of pumping during the previous irrigation season. This report also contains basic hydrologic data for 1950-77 that are provided for consideration in relation to the January 1977 water-level measurements.</p><p>The annual water-level measurements are made by personnel of the Division of Water Resources of the Kansas State Board of Agriculture and of the U.S. Geological Survey. State-agency support for this program is provided through the Kansas Geological Survey.</p><p>Wells in this report are numbered according to the Bureau of Land Management's system of land subdivision. In this system, the first set of digits of a well number indicates the township; the second set, the range east or west of the sixth prinicipal meridian; and the third set, the section in which the well is situated. The first letter denotes the 160-acre tract, the second, the 40-acre tract, and the third, the 10-acre tract. The letters are designated in a counterclockwise direction beginning in the northeast quarter of the section. Where there is more than one well in a 10-acre tract, consecutive numbers, beginning with "2", are added in the order in which the wells are inventoried.<br></p> application/pdf 10.3133/ofr77264 en U.S. Geological Survey January 1977 water levels, and data related to water-level changes since 1950, western Kansas reports
