• Bowie Resources Limited May 72, 2003 Bowie No. 2 Mine Annual Hydrology Report Table 4 contains a listing of all monitoring points, with descriptions of their locations and a reference to the Monitoring Point Table that contains this yeaz's monitoring data. All Drill Holes and Wells, with the exception of AW-2, 7-1Q have charts which present current and historic monitoring data. DH-13 and DH-34b were eliminated by mining during 1999. No Ponds have charts. Springs and streams with flows in excess of 5 gallons per minute and adequate historical data have charts included. Table 5 contains local precipitation data for 2002. This data is no longer available from the Internet at www.crh.noaa. og v/ei t• Daily precipitation are no longer available. 2002 data is presented as monthly compilations. Table 6 contains a listing of monitoring point charts. Points without charts either have insufficient monitoring events or have little evidence of water. Monitoring point tables and charts follow this introduction. Each Monitoring Point has an individual table which tabulates the annual data collection and reports Minimum, Maximum, Average and Baseline data. A reference in each footnote explains the period used for baseline data. • Flow data for the North Fork of the Gunnison river is obtained from the USGS from a website http://nwis-colo.cr.usgs.gov/historic.html. This flow reading is obtained telemetrically from a station near Somerset, CO and is reflective of upper river flows only. This monitoring point is identified by the USGS as 09132500. Flow data for the Fire Mountain Canal is obtained from the Division of Water Resources, Division IV, 1540 E. Niagara Street, Montrose, Colorado 81402. This flow is representative of the upper flow. Monitoring point identifiers near the mine portals are historic and follow no specific naming convention. Monitoring points located in areas monitored for the PR-04 permit revision follow a convention where the first letter(s) designates a water source type, such as "S" for Spring or "SP" for Spring and Pond. The numeral(s) following the first letter designate what Section the water source is located, for instance, SP34-2 would be a spring and pond in Section 34. The numeral separated with a dash indicates an index number for that point. SP34-2 would be the second monitoring point found in Section 34. NPDES Monitoring Points The mine has eight (8) discharge monitoring points. All three points were monitored according to permit requirements during periods of dischazge. Copies of the Discharge Monitoring Reports (DMR's) and the analysis of the dischazged waters which have been provided to the Colorado •
