groundwater and soil temperature throughout the area. The investigation was provided to the <br />Corps who concluded in a letter of July 14, 2010, that there are no jurisdictional wetlands and <br />other waters of the U.S. in upper Grassy Valley due to the lack of a "significant nexus ". <br />There are no wetlands or other waters of the U.S. in the other portions of the Wildhorse <br />Extension area. Most of the area is upland meadow on southwest - facing slope with well drained <br />soil (Photos WE -1 and WE -2). Dominant plants include bluegrass, fescue, brome grass <br />(Bromus inermis), yarrow (Achi/ /ea /anu /osa), and dandelion (Taraxicum ofcina /e). Shrubby <br />cinquefoil also occurs. Forest interspersed with upland meadow is present in the southern <br />portion of the area (Photos WE -3 and WE -4). There are no springs, seeps, or permanent water <br />sources in this area. <br />4.6 EAST CRESSON <br />Delineation of Potential Wetlands for Mine Life Extension 2 Project <br />Cripple Creek & Victor Gold Mining Company <br />This area is located in the Grassy Creek watershed downstream of CR 82 and includes meadow <br />and relatively dense mixed aspen /fir forest (Figure 2). The meadow in the northwest portion of <br />the area (see Photos EC -1 and EC -2) contains some tufted hairgrass (Deschampsia caespitosa) <br />and shrubby cinquefoil, both of which are wetland species; but this area is dominated by upland <br />species such as bluegrass, Junegrass, fescue, dandelion, and yarrow and has well drained soils <br />that lack any hydric indicators. Based on observations of the mining district, shrubby cinquefoil <br />is widespread throughout the mining district and is not a good indicator of wetland conditions. <br />Areas of forest are dominated by aspen and fir with a sparse understory (see Photos EC -3 and <br />EC -4) that does not contain any wetland species. There are no springs, seeps, or permanent <br />water sources in this area. <br />No wetlands or other waters of the U.S. exist in the East Cresson area. <br />5.0 CONCLUSIONS AND RECOMMENDATIONS <br />The presence of potential wetlands and other waters of the U.S. regulated under Section 404 <br />was evaluated for the five areas of new disturbance proposed for the MLE2 Project as part of <br />the Cresson Mine Project. This work was done using both past fieldwork and observations, <br />along with fieldwork completed for the areas in June 2011. <br />No wetlands or other waters of the U.S. were found in any of the five areas. It was determined <br />that Squaw Gulch would not be regulated based on the December 2008 guidance. Based on <br />July 2011 Bikis Water Consultants, LLC Page 7 <br />
