2011 Water Level Data Acquisition Statistics

KGS Open-file Report 2011-17
Dec. 2011


The field-measurement phase of the 2011 annual cooperative water-level measurement program was successfully completed by both the Kansas Geological Survey (KGS) and the Division of Water Resources (DWR), Kansas Department of Agriculture, prior to March 1, 2011. The annual program is designed to regionally sample the High Plains aquifer in Kansas so trends can be established and evaluated for effective incorporation into water-resource management strategies. Water levels were recorded in 98.7% of the 1,393 network wells in 2011. The KGS measured 504 wells and the three DWR offices (Garden City, Stafford, and Stockton) measured 889 wells. Data acquisition by KGS staff was completed in January.

Based on spatial analysis of the 2010 annual network-well distribution, 10 locations were identified that required additional water-level data to permit continuous and uniform sampling of the High Plains aquifer. Wells were identified in these locations with sufficient construction and historical information and landowner cooperation to attempt a water-level measurement. Of the 10 wells, 9 were actually measured. These 10 provisional wells were incorporated into the network for 2012 and will be measured in all future measurement campaigns unless the wells become unreliable or are plugged. Yearly geostatistical studies will define undersampled areas and will be used to select optimum locations for replacement wells to eliminate extraneous holes in the hexagonal network.
