Cheyenao q_q cif _r <br />The area of greatest decline in water levels of wells penetrating exclusively the Cheyenne aquifer was <br />east of Springfield where a -1.40 foot decline was recorded in 2002 as compared to a Cheyenne <br />aquifer maximum decline of - 5.30 feet in 2001 southwest of Springfield. The range of decline of the <br />Cheyenne aquifer for 2002 was -0.2 to -1.4 feet. The average 2002 decline was - 0.87 feet as <br />compared to -2.22 feet average decline in 2001. Rises of water levels of Cheyenne aquifer wells range <br />from +0.40' to +6.90'. In 2002, the average rise equaled +2.11 feet, as compared to the average rise <br />of +0.77 feet in 2001. <br />Dockum Aquifer <br />The Dockum aquifer declines range from - 0.30 feet east and south of Campo to -17.60c feet of <br />decline north of Walsh (as compared with -11.50 feet decline southwest of Stonington in 2001). The <br />arithmetic average of Dockum aquifer declines over the entire network was - 4.35 feet in 2002 as <br />compared to - 4.20 feet in 2001, and as compared to - 3.60 in 2000. Once again, seven Dockum <br />Aquifer wells experienced a rise averaging +1.20 feet in 2002 as compared to an average rise of +5.14 <br />in 2001. <br />Dakota /Cheyenne Q ui�ifer <br />Water level changes in wells producing from a combined Dakota -Cheyenne aquifer range from a +6.90 <br />foot rise north of Walsh to a -13.30 foot decline west of Pritchett. The average water level change of <br />Dakota/Cheyenne aquifer wells measured was - 0.51' change in 2002 as compared to +0.79' average <br />change in 2001. <br />W400R.cr <br />-5- <br />
