The field-measurement phase of the 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 February 1, 2006. 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 97.1% of the 1,332 network wells in 2006. The KGS measured 564 wells and the three DWR offices (Garden City, Stafford, and Stockton) measured 753 wells.
Spatial analysis of the 2005 annual network-well distribution revealed 31 locations that required additional water-level data to permit continuous and uniform sampling of the High Plains aquifer. Candidate wells for all 31 locations were identified through the cooperative efforts of the KGS, DWR, and the groundwater management districts. Twenty-five of the 31 candidate wells had sufficient construction and historical information and landowner cooperation to attempt a water-level measurement and were actually measured. These 25 were incorporated into the network for 2007 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.

In-field confidence in a particular measurement was qualitatively determined through inspection of chalk cut while general accuracy was quantitatively appraised using historical and local trends.

The two appendices to this report are summary tables.
Appendix A--Contains a summary of information for all wells measured by KGS. This appendix includes only county, well legal description (ID), and 2006 depth of water below ground surface (BGS). Quality Assurance measurements (QA) and Provisional wells (PROV) are also identified.
Appendix B--Contains a summary of information for all wells measured by DWR. This appendix includes only county, well legal description (ID), and 2006 depth of water below ground surface (BGS). Provisional wells (PROV) are also identified.
Both the current year's measurements and historical water-level data are archived and maintained at the KGS in a centralized database (WIZARD) that can be accessed at the KGS website at www.kgs.ku.edu/Magellan/WaterLevels/index.html. Just the Township-Range-Section identifier and the water level for each well measured are also provided in tabular form at www.kgs.ku.edu/Hydro/Levels/index.html.
