Groundwater 

The Kansas Geological Survey and the Kansas Department of Agriculture-Division of Water Resources cooperatively measure groundwater levels in the Upper Arkansas Subbasin.  There are a total of 100 groundwater wells in the alluvial, the Ogallala-High Plains and Dakota aquifers used for this analysis.  The Subbasin Water Resource Management Program measures wells in the winter, spring and fall.  Only winter -- December, January and February -- measurements were used in the Water Level Charts since those groundwater levels are considered to be least affected by pumping for irrigation.
