Effects on Springs in the Rapid Creek Basin <br />• Twenty-five springs were inventoried by the BLM in 1985 (Brooks, 1986). <br />Spring water is used by the town of Palisade, and discharge from the springs <br />flows through pipelines to a reservoir or directly to the Palisade water treatment <br />plant. <br />All inventoried springs in the Rapid Creek basin are above 6,800 feet; they <br />discharge from landslide, land-creep, and alluvial deposits; and nearly all are <br />perennial. The source of spring water is local. Precipitation from upper <br />elevations seep into unconsolidated material. This unconsolidated deposit <br />stores water until the water discharges at the contact between the <br />unconsolidated material and the bedrock (Brooks, 1986). <br />None of the springs are over the underground mine workings and most of the <br />springs are in areas outside the subsidence angle-of-draw. <br />• iso i ~ qs iswithi .t e,.aogJeo_f~dreawNfor~t~ell~Uni~,e~xTi~.i.sR~sprtngris~loaatedxaloagF <br />tF,~apjd1~r~ee~amd~'~iFar~t~h~e~so rUth"C'v"est~~mer~.of~S:eetion~8;a,.T;J;1~;S,~.Q,9;7aW~slt~is~+~- <br />yyitbuiurarn~ar~eatxprot'eateda8ro'm+rsUbsdeAce,:~. <br />Effects on Water Pipelines in the Rapid Creek Basin <br />The town of Palisade owns and maintains a raw water pipeline system along <br />Cottonwood Creek. A pipeline conveys water from Cabin Reservoir, along <br />Cottonwood Creek, to the confluence with Rapid Creek. A second pipeline <br />conveys raw water along Rapid Creek from collection points south-east of the <br />permit area. <br />Damage to pipelines adjacent to Cottonwood and Rapid Creeks is unlikely <br />because protective pillars will be left under both creeks. Refer to Tab Section <br />20 for detailed information regarding pillar design for subsidence control. <br />• 19-4 (New 3/1/96) <br />
