Name: <br />Denver, Colorado $0203 Doc. Date (if no date stamp): <br />RE: River Valley Resource, M-2001-090, Additional Adequacy Comment Responses <br />Dear Mr. Schreiner: <br />The following information is being provided in response to your additional comments dated <br />November ] 5, 2001. The order of our responses follows your comments. <br />6.4.4 EXHIBIT D -Mining Plan <br />17. . <br />To respond to the Division's comments regarding the Weiskopf and Suttle ditches, District 58 <br />Water Commissioner, Elvis Iaeovetto, was contacted. As discussed in responses to prior <br />Division comments, it is estimated that the continuous pumping rate for pit dewatering would be <br />approximately 150 to 300 gallons per minute, depending upon fluctuations in seasonal <br />groundwater levels. <br />Attached is a sketch of the proposed site and the numerous local ditches that occur in the <br />vicinity. We are providing this and the following descriptions to better illustrate irrigation <br />ditches, irrigation waste water return flows to the Yampa River, and irrigation water totally under <br />the control of the More Family Ranches. <br />The Shear/Summer Goldsworthy Ditch delivers water to the O'Dell property on the west of the <br />More property and to'the Shear property'to the northwest of the More property before returning <br />to the river via McKinnis Creek. <br />The Suttle Ditch is diverted off the Yampa River on the south side. A portion of the ditch <br />crosses under the river in a siphon on the southern boundary of the More property and delivers <br />water to the Mores, O'Dells and the Hudspeths before discharging to McKinnis Creek. <br />The Weiskopf Ditch (whose headgate has been abandoned) flows along the base of the hillside <br />on the east of the More property and delivers water only to the More property. Irrigation waste <br />water flows from this ditch collect in what the locals call the Little River, which is the large <br />Swale crossing the More property from the south to the north generally in the center of the <br />proposed mine site. Water then flows north across the Romick property and under County Road <br />20 through 4 - 48" culverts where it then joins McKinnis Creek to return to the Yampa. There <br />are rio water rights associated with this ditch downstream of the More property. <br />1499 West 120th Avenue, Suite 200 vrww.applegategroup.com 5441 Boeing Drive; Suite 200 <br />Denver; Colorado 80234-2728 Loveland, Colorado 80538-8855 <br />
