Gunnison No. 1 Mine, <br />CMLRD Permit No. C-007-80. <br />Dear Susan: <br />The following discussions and enclosures address <br />adequacy comments raised in your June 17, 1987 <br />letter. The attachments should be inserted in Volume <br />1, Sections 2 and 4 of the Mt. Gunnison No. 1 M & R <br />Plan on the appropriate pages. <br />Our responses to the adequacy comments are as <br />follows: <br />1. The information regarding the Upper Dry <br />Fork Flume is somewhat mis-stated in the <br />application. The Upper Dry Fork Flume is <br />located in an acceptable location with <br />respect to actually measuring the necessary <br />flows; however, the problem lies in the <br />fact that much data for the past year was <br />lost due to Beaver activity just below the <br />flume. There are two possible <br />alternatives: 1.) Move the flume upstream <br />approximately 1/8 to 1/4 of a mile if there <br />is an acceptable location. 2.) Outline a <br />program, gain the necessary approvals from <br />the Colorado ^ivision of Wildlife, the <br />U.S.F.S., etc. and have the animals trapped <br />or otherwise removed from the area. <br />Currently WECC and WATEC (WECC hydrology <br />monitoring consultant) are working to <br />determine the best long term solution to <br />the problem. There are several items that <br />must be looked at including: 1.) time and <br />effort involved with the two alternatives <br />2.) will moving the flume solve the Beaver <br />problem 3.) is there a good alternate site <br />for the flume, etc. We would like to <br />either move the flume or trap the Beavers <br />this summer (1987) however, due to a large <br />landslide across the main access road into <br />AMCO-620a <br />
