2002 Annual Water Level Raw Data Report for Kansas

Conclusions

The field measurement phase of the annual cooperative water level measurement program was successfully completed by both the KGS and DWR prior to February 1, 2002. 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 94.6% of the 1,358 network wells with data quality evaluations completed on the 510 KGS wells. Modifications to the acquisition methodology developed after statistical analysis of the 1997, 1998, and 1999 KGS annual measurements were implemented during 2000, continuing in 2001 and 2002. Systematic errors detected in water level data collected from 1997 to 2001 provide valuable clues to long-term improvement in network reliability.

Spatial analysis of the 2001 annual network well distribution revealed 13 locations that required additional water level data to permit continuous and uniform sampling of the High Plains Aquifer. Candidate wells for all 13 locations were identified through the cooperative efforts of the KGS, DWR, and the GMDs. Of those 13 candidate wells, 12 had sufficient construction and historical information and landowner cooperation to attempt a water level measurement and were actually measured. The 12 were incorporated into the network for 2002 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.
