III: 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,
1999. 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 95% of
the 1,402 network wells with data quality evaluations completed on the 556 KGS
wells. Modifications to the acquisition methodology developed after statistical
analysis of the 1997 and 1998 KGS annual measurements were implemented during
1999. Systematic errors detected in the 1997 and 1999 water level data provide
valuable clues to long-term improvement in network reliability.
Spatial analysis of the 1998 annual network well distribution revealed 37
locations that required additional water level data to permit continuous and
uniform sampling of the High Plains Aquifer. Candidate wells for all 47 locations
were identified through the cooperative efforts of the KGS, DWR, and the GMDs.
Of those 47 wells, only 34 had sufficient construction and historical information
and landowner cooperation to attempt a water level measurement, with 14 actually
being measured. The 14 are incorporated into the network for 1999 and will be
measured in all future measurement campaigns unless the wells become unreliable
or are plugged. Yearly geostatistical studies will define under-sampled areas and
will be used to select optimum locations for replacement wells to eliminate
extraneous holes in the hexagonal network.
