Abstract

Three contour maps of groundwater elevation levels below Hays, Kansas generated in 2016 show that the phreatic surface in eight monitoring wells declined 3.6 inches to 1 foot 9.6 inches over a three-month period of July, August, and September. They also indicate that groundwater flows in curvilinear directions toward Big Creek. Analyses of ten north-south oriented structural cross sections of the alluvial fill beneath the central region of Hays provide evidence of buried low-sinuosity and meandering streams, floodplains, and possibly adjoining tributaries and abandoned channels. Correlation of the more porous and permeable sand and gravel facies along a northwest to southeast flow direction suggests a possible subsurface paleochannel within the Big Creek alluvium. This information is useful in determining hydraulic connectivity within the alluvium, mobility of various contaminants, and future watershed analyses.
