This letter is accompanying the results of our most recent site <br />visit where we pulled groundwater level readings from our various monitoring wells and transducers <br />located on -site. There were three monitor wells on the site; MW -1 (east), MW -2 (south) and MW -4 <br />(west), as well as two pressure transducers recording groundwater level readings every hour. The <br />pressure transducers are located in MW -4, as well as in the lined reservoir located on the south end of <br />Brannan Pit #29. Attached are the report showing the well measurements taken on April 22, 2013 <br />and a figure showing the location of the monitoring wells. <br />We have had the appropriate locations of the transducers surveyed for a correct elevation reading, <br />and have compared the elevation of the water table underneath MW -4 to the water surface elevation <br />at the reservoir. A plot of our hourly measurements is also included. <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 & Fred Marvel, Brannan Sand and Gravel <br />AG File No. 10 -116 <br />N. \10116 Brannan Pit 29\Disciphnes (Technical) \WRPM\Water Rights\2013 Reports \TR report 4.22 13.docx <br />1490 W. 121" Avenue, Suite 100 <br />Denver, CO 80234 <br />303 - 452 -6611 <br />www.applegategroup.com <br />RECEI V -fl <br />APR 2U ? <br />"VISION OF RECLAMATION <br />MINING AND SAFETY <br />118 W. 6 Street, Suite 100 <br />Glenwood Springs, CO 81601 <br />
