<br />Foidel creek, north of Pinnacle Peak. USGS gaging hydrographs of these <br />data are presented in Table 13, USGS Caging Station Measurements. As <br />these data indicate, water availability in the study area is erratic from <br />year to year and continuous flow occurs during only two months out of the <br />year in response to snowmelt. According to the original decree (October 8, <br />1908) on the Eclm~an Park Reservoir and Ditch System, Ditches 3, 4 and 5 <br />probably were used to irrigate the study area. 't'hese ditches irrigated <br />the area, according to the decree, as follows: <br />• Totals: <br />Ditch Acres Irrigated Design Flow <br />3 397 7.66 <br />4 34 4.06 <br />5 36 4.06 <br />467ac 15.78cfs <br />The total amount of flow measured at EF'C weir site 9, at the down- <br />stream end of the study area as shown on the Twentymile Park Hydrology <br />(Map 6), was 94 acre-feet from May 1 through September 15, 1979 (Table 12). <br />94 acre-feet divided by 467 acres of irrigable land equals 0.20 ac-ft per <br />acre. This is much less than the twv acre-feet of water per acre frwn <br />May 1st to September 15th required for flood irrigation on the OSM <br />Technical cliideline. It is concluded, therefore, that the quantity of <br />water in the Eclanan Park study area is inadequate for flood irrigation. <br />Aerial Photograph Analysis <br />Aerial photographic croverage of the mine plan, adjacent, and general <br />area was provided by OSM personnel in Denver, Colorado. A sample of <br />• three color infrared aerial photographs with interpretations by a private <br />consultant is provided in Exhibit 12, Color Infrared Aerial Photography. <br />785-9(k) <br />
