UPPER BLACK SQUIRREL CREEK DE5IGNATED GR�UN� WATER BASIN <br />WATER LEVEL MEASUREMENTS <br />2ooa <br />This report represents the results of wate� le�eR measurements of wells in the Upper Black <br />Squir�el Creek Designated Basin made during the month of February 20�4. The project was <br />done in cooperation with the Upper Black Squirrel Creek G�ound V1Jater Managemen# District and <br />locai well owners. Funding for this prv�ect was supplied in part from well permit fees collected and <br />managed by the ��ce of the State Engineer as a result of the passage of Senate Bili 200 during <br />the 1987 legislati�e session. <br />A new report format was created for this year's report. This is the result of placing ail <br />sfatewide water le�el data into HYDR4BASE, which is a uniform da#abase for aA data collected <br />and managed by the Di�ision of Water Resources. Tabular data are presented for each well for <br />the previous 1 � years. Graphical data are presented for the entire period of record. Information <br />concerriing bedrock wells for the Denver Basin Aquifers wi11 generally be a�ailable in June of each <br />year and can be obtained from the 4ffice of the State Engineer. <br />A total of 20 weil sites were �isited with 19 wells being measured, recorded and data <br />entered. Changes in water le�el from last year's readings for the allu�ial aquifer range from a <br />decline of —22.6 feet in BS-10R (Sec.8, T.14 S., R,fi2 W.} to a rise of 15.94 feet in BS-7 (Sec.fi, <br />T.14 S., R.62 W.}. The greatest decline in 2004 was almost ten feet more than in 2003. The <br />highest rise in 20�4 was 14 feet more than the previous year. The average decline for the entire <br />basin was —0.07 feet for the period 2��3 to 2D04, as compared to an average decline of -4.33 feet <br />during the 2��2 to 2�03 penod. A total change for the 5-year period 1999 to 2�04 ranges from a <br />decline of —25.41 feet in BS-19 (Sec. 26, T.13 S., R.63 W.} to a rise vf 1 fi.55 feet in BS-15A {5ec. <br />Z5, T.13 S., R.fi3 W.} The average decline for the 5-year period is —1.18 feet per year as <br />compared to an a�erage of —1.04 feet for the 5-year period 1998 to 20D3. �ver the past ten years <br />�1994 to 2��4}, �he average water le�e1 in the basin has risen D.fi2 feet. <br />This ground water basin has a long and unvaried history of continuing ground water <br />declines. This decline is persistent even though the latest � 0-year average suggests that some <br />recharge may be taking place. Measurements in future years will be necessary to determine if the <br />recharge trend continues. The recurring and persistent areas of intense ground water use <br />indicate that a metering program is warranted to adequately manage the water resources vf the <br />Upper Black Squirrel Ground Water Management District. <br />This year's report was prepared under contract to George D. VanSlyke, PG, Consulting <br />Ground Water Geologist. <br />Copies of the report can be purchased from the �ffice of the State Engineer, Records <br />Section, 1313 Sherman St. Denver, C4 802�3, (303} 8fi6-3447. <br />
