This report represents the results of water level measurements of wells in the Upper Black Squirrel Creek <br />Designated Ground Water Basin made February 8, 2000. This project was done in cooperation with the <br />Upper Black Squirrel Creek Ground Water Management District and local well owners. This year, as in <br />past years, this funding for this project was supplied in part from well permit fees collected and managed <br />by the Office of the State Engineer as a result of the passage of Senate Bill 200 during the 1987 <br />legislative session. <br />A total of 20 wells were measured and recorded, while 26 sites were visited. Changes in water level from <br />last year's readings for the alluvial aquifer range from a decline of —2.05 feet in T14S, R63W, Sec. 24, to a <br />rise of 13.25 feet in T14S, R62W, Sec. 6. The lowest decline in 2000 was 6.35 feet less than the lowest <br />decline in 1999. The highest rise was 8.32 feet higher than the highest rise of 1999. The average decline <br />for the entire basin was 0.70 feet for 1999-2000 measurements as compared to an average decline of <br />1.87 feet during the period 1998-1999. A total change for the 5 -year period of 1995 to 2000 ranges from a <br />decline of --9.04 feet in T13S, R62W, Sec. 7 to a rise of 8.40 feet in T14S, R62W, Sec. 24. The average <br />decline for the last 5 -year period is —3.57 feet per year (1995-2000), as compared to an average decline of <br />—1.13 feetlyear for the 5 -year period (1994-1999). <br />Results of the measurements of Denver Basin bedrock wells will be published in the annual report for the <br />bedrock aquifers which will be available in June of this year. <br />The table of water level measurements included in this report is organized by location. Information <br />presented includes location, water levels measured prior to the 1988 measurements made by this office, <br />the 1988 through 2000 measurements and changes between 1999/2000 and 1995 to 2000. Also <br />included are 17 well hydrographs of wells measured in the basin (with 5 or more years of record). The <br />final three pages of this report are maps of water level decline from the initial water level measurements to <br />the 1998, 1999 and year 2000 measurements. <br />Copies of this report are being made available to well owners for their assistance in this project. <br />Additional reports are available from the Office of the State Engineer, 1313 Sherman Street, Room 818, <br />Denver, Colorado 80203, for a cost of $3.00. <br />W 102R.cgr <br />2129100 <br />
