• The photographs aze at a scale of appr~Y~~tely 1:34,000 and were <br />taken in September, 1978. The three photographs cover the mine plan and <br />adjacent area as follows: <br />Photo No. 616: Energy Mine No. 1 and Middle Creek <br />Photo No. 630: Energy Mine No. 2 and Fish Creek <br />Photo No. 632: Eclanan Park Mine and Foidel Creek <br />The photographs show the fall season differences in vegetative growth <br />between upland and valley floor areas. These photos, along with a set of <br />black and white aerial photos giving sterographic coverage of the same <br />areas, were sent to the wnsulting firm I~2C, Incorporated (NRC) for <br />analysis. The interpretations by NRC aze s•+~rized as follows: No <br />alluvial valley floor exists in or adjacent to the study area; 10 percent <br />• or less of the Middle Creek flood plain adjacent to Enexyy Mine No. 1 <br />could be an alluvial valley floor; Host of the Fish creek flood plain <br />adjacent to Energy Mine No. 2 is probably an alluvial valley floor; and <br />one area just west of Reservoir No. 1 outside the mine plan area on upper <br />Foidel creek might be an alluvial valley floor. No evidence was found to <br />indicate by vegetative growth any conclusion that an alluvial valley <br />floor exists in the study area. <br />Effects on Essential Hydrologic Functions <br />Based on the information accimiulated in the reconnaissance and field <br />investigations and the baseline data wllection program, the effects of <br />mining on any alluvial valley floors which may exist downstream from the <br />mine plan area have been evaluated. Mining will not directly impact any <br />alluvial valley floor; however, the possible indirect effects of mining <br />• on the essential hydrologic functions of alluvial valley floors are <br />discussed below. <br />785-9(1) <br />
