• Bowie Resources Limited July 1, 2002 <br />Bowie No. 2 Mine <br />Annual Hydrology Report <br />Table 4 contains a listing of all monitoring points, with descriptions of their locations and a <br />reference to the Monitoring Point Table that contains this yeaz's monitoring data. All Drill Holes <br />and Wells, with the exception of AW-2, 7-10, have charts which present current and historic <br />monitoring data. DH-13 and DH-34b were eliminated by mining during 1999. No Ponds have <br />charts. Springs and streams with flows in excess of 5 gallons per minute and adequate historical <br />data have charts included. TR-34 removed DH-60, DH-65 and B03 from the sampling regime. <br />The Orchard Valley West Mine fill well (OV WM) was destroyed by mine reclamation. <br />Table 5 contains local precipitation data for 2001. This data is no longer available from the <br />intemet at www.crh.noaa.eov/eit. Daily precipitation records may not be available next yeaz. <br />Table 6 contains a listing of monitoring point charts. Points without charts either have <br />insufficient monitoring events or have little evidence of water. <br />Monitoring point tables and charts follow this introduction. Each Monitoring Point has an <br />individual table which tabulates the annual data collection and reports Minimum, Maximum, <br />Average and Baseline data. A reference in each footnote explains the period used for baseline <br />data. <br />~ Flow data for the North Fork of the Gunnison river is obtained from the USGS from a website <br />http://nwis-colo.cr.usgs.gov/historiahtml. This flow reading is obtained telemetrically from a <br />station near Somerset, CO and is reflective of upper river flows only. This monitoring point is <br />identified by the USGS as 09132500. <br />Flow data for the Fire Mountain Canal is obtained from the Division of Water Resources, <br />Division N, 1540 E. Niagara Street, Montrose, Colorado 81402. This flow is representative of <br />the upper flow. <br />Monitoring point identifiers neaz the mine portals are historic and follow no specific naming <br />convention. Monitoring points located in areas monitored for the PR-04 permit revision follow a <br />convention where the first letter(s) designates a water source type, such as "S" for Spring or "SP" <br />for Spring and Pond. The numeral(s) following the first letter designate what Section the water <br />source is located, for instance, SP34-2 would be a spring and pond in Section 34. The numeral <br />separated with a dash indicates an index number for that point. SP34-2 would be the second <br />monitoring point found in Section 34. <br />NPDES Monitoring Points <br />The mine has three (3) dischazge monitoring points. All three points were monitored according <br />to permit requirements during periods of discharge. Copies of the Discharge Monitoring Reports <br />(DMA's) and the analysis of the dischazged waters which have been provided to the Colorada <br />2 <br />
