This report contains the basic ground water level data coliected in the Upper Big Sandy Designated Ground Water Basin during the period from February 199� through February 2006. Acquisition and pubfication of this information is a cooperative effort between the Upper Big Sandy Ground Water Management District and the Colorado Division of Water Resources. The project is part of a statewide ground water le�el monitoring program funded by Senate Bill 2�0 (1987 legislati�e sessfon}. This legislation directed that a portion of the fees collected for water weli permit applications be used for the establishment of a program to monitor water leve! trends throughou� the state. With the exception of one group of wells, the wells in #his report are listed by township, range, and section, beginning at the north end of the basin and proceeding south. The exception consists of five of the seven monitoring and production welis owned by the Town of Limon. The data sheets for the fi�e monitoring wells located in #he vicinity of the town have all been placed together a# the back of the report. The Iocations of these five wells are shown on a map or maps included with the data sheets. The data sheets for the town's Frasier Farms production well and the well identified as Big Sandy No. 4 are indexed by location. Maps are included with the report that show the locations of wells in both groups. The report contains water level m�asurements for twenty-nine wells monitored on a regular basis. �ne well could not be measured in February 2�06 because it had been converted from an irrigation we!! to a domestic water supply well, and down hole pumping equipment obstructed the well bore. Hydrographs are presented for wells with more than fi�e annual measurements. Water ie�el measurements in wells were taken on February 20 and February 21, 200fi. The twenty-nine wells measured for this year's report show an a�erage water le�el decline vf -0.18 foot since March of 2��5. Water le�els increased in eight of the wells, and decreased in nineteen of the we(Is, and remained the same in two wells. The changes ranged from an increase of 1.08 feet to a decline of —1.25 feet. The Town o� Limon's Christopher Well Field welfs, wiih the exception of one well, which remained the same, showed increases in the s#atic water le�el. For the last fi�e years, ground water levels have declined at an a�erage rate of —0.39 foot per year, whereas over the fast ten years, the a�erage rate of decline has been —0.08 foot.
