Nov. 2012
The field-measurement phase of the 2012 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, 2012. 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 97.9% of the 1,393 network wells in 2012. The KGS measured 498 wells and the three DWR offices (Garden City, Stafford, and Stockton) measured 895 wells. Data acquisition by KGS staff was completed in January.
Based on spatial analysis of the 2011 annual network-well distribution, 13 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. All 13 wells were measured. These 13 provisional wells were incorporated into the network for 2013 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.
