• z.oa.~ <br />Riparian vegetation occurs near the seeps in the colluvial material. A few <br />willows, sedges, grasses and other riparian vegetation extend from the <br />seeps to the colluvial deposits. They are not extensive. <br />Groundwater occurrences within the Mesaverde formation have been <br />analyzed using the piezometer data gathered for the mine site area. That <br />data shows that there is groundwater in the coal seam but, as described <br />earlier in this report, should not be of any significant influence to the <br />hydrologic regime. <br />(2) Surface Water Information. <br />(a) and (b) <br />The surface water information is organized in the following categories; 1) <br />Watershed, the river and stream network beginning at the Colorado River; <br />2) the North Fork of the Gunnison River; 3) streams draining the permit <br />and adjacent area; 4) stockponds within the permit and adjacent area; and <br />5) surface water on the mine site. <br />Watershed <br />The proposed mine plan and adjacent area lie within the Upper Main Stem <br />of the Upper Colorado River Region in Colorado. The Upper Main Stem is <br />composed of nine major sub-basins: Middle Park, Eagle River, Roaring <br />Fork, Rifle-West Divide, Grand Valley, Upper Gunnison, North Fork, <br />Uncompahgre, and Whitewater. Altitudes range from about 4,300 feet on <br />the Colorado River at the Colorado-Utah state line to over 14,000 feet on the <br />Continental Divide, which forms the eastern margin of the watershed. Only <br />the North Fork may be affected by the Bowie #2 Mine. <br />North Fork of the Gunnison River <br />A USGS gauging station (No. 09132500) is located 2.3 miles east of <br />Somerset and 4.8 miles upstream from Hubbard Creek. The period of record <br />is October 1933 to current year. The gauge is a water-stage recorder with <br />satellite telemetry about 6280 feet above sea level. <br /> <br />PR-03 2.04 - 30 - 5/99 <br />
