Water Levels in the Southern High Plains Page 2 <br />Designated Ground Water Basin - 1997 <br />A review of the 1997 measurements as compared to the 1996 measurements reveals that the <br />following water level changes have occurred since the last measurement period (1996): <br />water level declines = 20 wells as compared with 37 between 1995 and 1996 <br />water level rises = 45 wells as compared with 22 in the 1995-96 report <br />no measured change in water level = 1 well as compared to 6 in 1995-96 period <br />The reader will note that where water level is zero with no additional data entry, that no water <br />level measurement was taken during those subsequent measurement periods. <br />The average decline of water level within the network was 1.35 feet for 1997 as compared to <br />2.95 feet for 1996 and 3.67 for 1995. <br />The average rise in water level was 2.28 feet for 1997 as compared to 1.10 feet in 1996 and <br />2.19 in 1995. <br />A map depicting the location of monitoring wells, as well as individual well data and selected <br />well hydrographs, has been modified by GPS information and replacement well information and <br />follows this text. Additionally, a listing entitled "Well Locations" lists the GPS results for all well <br />sites visited in 1996 and 1997 and utilized in the GIS map as well as 1997 data not yet <br />incorporated in the map. <br />Ogallala Aquifer <br />The Ogallala aquifer experienced declines in only two wells with values of -0.01 and -0.30 feet. <br />Numerous wells experienced rises in water levels. The average rise was + 1.82 feet as <br />compared to -1.84 feet of decline in 1996. The areas of mostly rises of water table in the <br />Ogallala aquifer are northeastern Baca and southeastern Prowers counties, which have been <br />areas of decline in 1996, 1995, and 1994. <br />Dakota Aquifer <br />In 1997, water level data indicates only two wells completed exclusively in the Dakota aquifer <br />experienced declines of -0.50 and -0.3 feet. <br />Chevenne Aquifer <br />The area of greatest decline in water levels of wells penetrating exclusively the Cheyenne aquifer <br />was northeast of Two Buttes where a -6.25 foot decline was recorded in 1997 as compared to <br />a Cheyenne aquifer decline of -10.7 feet in 1996. The range of decline of the Cheyenne aquifer <br />for 1997 was -0.6 to -6.25 feet. The average decline was -1.87 feet as compared to -2.47 feet <br />average decline in 1996. <br />Dockum Aauifer <br />The Dockum aquifer declines range from -0.10 feet in northeast Baca County to -0.90 feet of <br />decline south of Stonington (as compared with -8.0 feet decline south of Stonington in 1996). <br />The arithmetic average of Dockum aquifer declines over the entire network was -0.51 feet in <br />1997 as compared to -3.08 feet in 1996 as compared to -4.57 in 1995. <br />
