Water Levels in the Southern High Plains Page 2 Designated Ground Water Basin - 1995 A review of the 1995 measurements as compared to the 1994 measurements reveals that the following water level changes have occurred since the last measurement period (1994-95): water level declines = 42 wells as compared with 46 between 1993 and 1994 water level rises = 24 wells as compared with 23 in the 1993-94 report no measured change in water level = 10 wells The average decline of water level within the network was 3.67 feet as compared to 3.31 feet last year. The average rise in water level was 2.19 feet as compared to 2.28 feet last year. A map depicting the location of monitoring wells, as well as individual well data and selected well hydrographs, follows this text. Water level change maps were scheduled for the 1995 report. However, change maps would be more meaningful and useful if more individual wells were completed entirely within a specific aquifer rather than multiple aquifer construction. Ogallala Aquifer The Ogallala aquifer experienced typical declines of 1-3 feet, with a maximum decline of -3.18, as as noted below. One well experienced a small rise in water level. The average decline was -1.48 feet. The area of greater decline of water table in the Ogallala aquifer again in 1995, as it was in 1994, is northeastern Baca and southeastern Prowers counties. Dakota Aquifer Again, as in 1994, 1995 water level data indicates northeastern Baca and Southeastern Prowers counties' areas with the greatest decline in water levels, approximately 4 to 5 feet. Again, in 1995, the greatest decline in water level in the Dakota aquifer is in the area near Blaine. The 1995 arithmetic average of decline is -6.34 feet, as compared to an average decline of -3.85 in 1994. The range of decline of the Dakota aquifer was from -1.30 feet to -13.5 feet. Cheyenne Aquifer The area of greatest decline in water levels of wells penetrating the Cheyenne aquifer only was northwest of Edler where a 13.6 foot decline was recorded in 1995. The range of decline of the Cheyenne aquifer for 1995 was generally -0.30 to -13.6 feet. The average decline was -4.84 feet. Dockum Aquifer The Dockum aquifer declines range from -0.60 feet in southeast Baca County to -19.9 feet of decline southeast of Stonington. The arithmetic average of Dockum aquifer declines over the entire network was -4.57 feet. Dakota/Cheyenne Aquifer Water level changes in the Dakota -Cheyenne aquifer range from a 14.60 foot rise south of Blaine to a -8.80 foot decline west of Blaine. The average water level change of Dakota/Cheyenne aquifer wells measured was 0.55 feet of rise. 4698R.CR
