Applegate / <br />Group,inc. <br />Water Resource Advisors for the West <br />April 2, 2013 <br />Mr. Berhan Keffelew <br />Division of Reclamation, Mining and Safety <br />1313 Sherman Street, RM 215 <br />Denver, CO 80203 <br />✓ V <br />RE: Brannan Sand & Gravel Company Pit 29, Permit No. M- 1980 -183, Water Level Monitoring <br />Dear Mr. Keffelew: <br />Pursuant to Revision TR -3 we are submitting the monitor well measurements for the quarter ending <br />March 31, 2013. There were three monitor wells on the site; MW -1 (east), MW -2 (south) and MW -4 <br />(west). The well MW -3 has been abandoned, and MW -4 has been added as a replacement. Attached <br />is the report showing the well measurements taken on April 1, 2013, and a figure showing the <br />location of the monitoring wells. <br />We would also like to note that we have, as of February 4, 2013, placed a pressure transducer in the <br />reservoir on the east side of the property. (An additional pressure transducer was placed in the <br />monitoring well (MW -4) on January 3, 2013.) These transducers will take readings once every hour, <br />and we will be able to access these readings when we visit the site periodically. We have had the <br />appropriate locations of the transducers surveyed for a correct elevation reading, and have compared <br />the elevation of the water table underneath MW -4 to the water surface elevation at the reservoir. A <br />plot of our hourly measurements is also included. You'll note on the plot that the water surface <br />elevation increases dramatically beginning on March 22, 2013. This increase was caused by a filling <br />of the reservoir at a constant rate from 2:00 pm on March 22n through 5:00 pm on March 25 <br />If you have any questions please call me at your convenience. <br />Cordially, <br />Applegate Group, Inc. <br />Stephen Buechner <br />Water Resource Engineer <br />SB /ta <br />Enclosures <br />cc: Eugene Riordan, Esq. <br />Theran Olsen, Brannan Sand and Gravel <br />AG File No. 10 -116 <br />N \10116 Brannan Pit 29\Disciplines (Technical) \WRPM \Water Rights\2013 Reports \TR report 3 13 docx <br />1490 W. 121 Avenue, Suite 100 <br />Denver, CO 80234 <br />303 - 452 -6611 <br />www.applegategroup.com <br />RECEIVE <br />7 PR 04 2013 <br />DIVISION OF RECLAMATION <br />MI NINGAN®SAFET1. <br />118 W. 6 Street, Suite 100 <br />Glenwood Springs, CO 81601 <br />
