within a distance of a mile further north. The strata around the D seam <br /> consist primarily of shales with thin interbedded sandstones. The total <br /> in-place coal reserves of the D seam on the tract are estimated to be <br /> approximately 28.5 million tons. <br /> In 1979, the Orchard Valley Mine produced 722,470 tons of coal . <br /> Mining is now occurring in the North Mains of the subject lease area, <br /> and in the First West Panel . More detailed information on the coal <br /> resource of the lease tracts is found in EAR CO-030-7-79 and TE/EAR <br /> CO-030-9-34. <br /> Water Resources <br /> Currently, CWI' s industrial water supply for the Orchard Valley <br /> _Mine is their 25 percent interest in the Lost Lake Slough (East Beckwith <br /> No. 1 Reservoir) located about 48 miles upstream from Paonia on a tri- <br /> butary to Anthracite Creek. CWI ' s 25 percent interest yields more than <br /> 100 acre feet of storage water each year. <br /> -The Lost Lake water is exchanged to the Stevens Gulch wells via an <br /> Augmentation. Plan that has received final approval by the Water Court <br /> (Reference W-3106; Referee' s Ruling September 22, 1978; Judgement and <br /> Decree of Water Court October 19, 1978). <br /> This tract lies on the moderately- dissected southern slopes of <br /> Grand Mesa. Surface streams drain generally southward to the North Fork <br /> of the Gunnison River. . Streams flowing across this area are inter- <br /> mittent (Stevens Gulch) or ephemeral and flow during wet years or during <br /> the spring months of most years. <br /> The tract is underlain to below the level of the North Fork River <br /> by a thick sequence of interbedded sandstone, siltstone, coal , and shale <br /> beds that dip 6 degrees to the north-northeast away from the valley. <br /> The D seam, which would be mined, slopes away from the North Fork <br /> Valley and crops out south of this tract in an elongate band high on the <br /> steep sideslopes north of and about 600 feet above the river level . <br /> CWI has identified eight stockwater ponds, springs, and reservoirs <br /> on or immediately adjacent to this tract. Of the springs present in the <br /> area, most produce less than two gallons per minute. There is no esti- <br /> mate of the cumulative discharge or water quality from springs on the <br /> tract. <br /> None of the area of this tract lies on an alluvial valley floor or <br /> in a 100-year floodplain. A complete description of the hydrology of <br /> the area is contained in the CWI EAR (1977). <br /> Soils <br /> The soils range from deep, 'nearly level alluvial soils along the <br /> North Fork to shallow, stony soils and rock outcrop on the steep moun- <br /> tain slopes. <br /> 9 <br />
