Kansas Geological Survey (KGS) conducted a groundwater
availability study in Groundwater Management District 4 (GMD4),
located in northwest Kansas. The goal of the study was definition
of the hydrogeologic variables that can be used to predict the
of groundwater level declines in the future. The study has two
township-scale (approximately 40 square miles in each area) study
areas--one where the rate of water level decline is very
slow (termed the "safe" area)
and a second where the rate of water level decline is much
more rapid (termed
the "stressed" area).
In both areas, the GMD4 and KGS staff established a multi-well
water level monitoring program using existing irrigation wells.
Nine wells in the safe area and 16 wells in the stressed area
were monitored at least monthly. One well in each area had a
transducer installed to obtain a continuous water level record
hydrographs). Data on the annual
water use for all wells in each area for the time period from
was compiled into a GIS database. Compilation and evaluation
of the geologic data from ground surface down to bedrock was
