UPPER BLACK SQUIRREL CREEK DESIGNATED GRDUND WATER BASIhI <br />WATER LEVEL MEASUREMENTS <br />zoo7 <br />This report represents the results of water level measurements of wells in the LJpper Black <br />5quirrel Creek Designated Basin made during March, 20�7. The project was done in cooperation <br />with the Upper Black Squirrei Creek Ground Water Management District and loca! well owners. <br />Funding for this project was supplied in part from well permit fees collec#ed and managed by the <br />Office of the State Engineer as a result of the passage of Senate Bill 200 during the 1987 <br />legisla#i�e session. <br />Tabular data are presented for each well for the previous 1 Q years. Graphical data are presented <br />for the entire period of record. Information concerning bedrock wells for the Denver Basin <br />Aquifers will generally be available in June of each year and can be obtained from the Office of <br />the State Engineer. A complete set of historic tabuiar data for the Upper Black Squirrel Creek <br />Designated Ground Water Basin is avaifable by calling the ��ce of the State Engineer. <br />The wells in this report are listed by township, range, and secti�n, beginning at the north end of <br />the basin and proceeding south. <br />A total of 25 weN sites were visited in 2007 with 21 weils being measured, recorded and data <br />entered. Two irrigation wells (BS-19 and BS-25) and one stock wel{ (BS-24) were pumping and <br />could not be measured. Also, BS-01 had been plugged and abandoned, and the weil head <br />configuration of its repiacement, designated BS-01A, was inaccess�ble fvr making measurements. <br />Changes in water levefs from last year's readings for the alluvial aquifer range frvm a decline of <br />-1,93 feet in BS-O7 to an increase of 5.85 feet in BS-04. For #he basin, there was an average <br />increase in water levei ofi D.48 feet for the period 2�06 to 2007, as compared to an average <br />decrease of -0.82 feet during the 2�05 to 2�a6 period. The average decline for the 5-year period <br />2�02 to 2007 is —4.21 feet per year. �ver the past ten years (1997 to 2D07}, the average water <br />levels in the basin ha�e risen D.17 feet per year. <br />Cop�es of this report can be purchased from the �ffice of the State Engineer, Records Section, <br />1313 5herman St., Room 821, Denver, C4 80203, {303} 8fifi-3447.
