January 1984 water levels, and data related to water-level changes, western and south-central Kansas

Abstract

This report provides hydrologic data related to water-level measurements made in about 1450 observation wells in western and south-central Kansas during January and February 1984. Water-level measurements are made in mid-winter of each year to minimize the effect of seasonal pumping. However, a few water-level measurements that are made in mid-winter of some years may reflect either the effects of recent pumping from the observation well or by nearby wells or the effects of barometric-pressure changes. Average water-level changes for the four reported areas were computed for various time intervals. In northwetern Kansas, the average water-level decline was 0.6 foot during 1983, and the average rise was 0.9 foot during 1982. The average annual water-level decline was 0.6 foot for the 18-year period from 1966-83. In west-central Kansas, the average decline was 0.7 foot during 1983, and 0.2 feet during 1982. For 1966-83, the average annual decline was 1.5 feet. In southwestern Kansas, the average water-level decline was 0.4 feet during 1983, and 1.8 feet during 1982. The average annual decline was 1.7 feet during 1966-83. In south-central Kansas, the average water-level decline was 0.2 foot during 1983, and 0.8 foot during 1982. The average annual decline was 0.4 footmore » during 1974-83. Water levels declined an average of 0.5 foot during 1983 throughout western and south-central Kansas. 2 figs., 1 tab.« less
