horizons, and observation of water sources. The presence of plant species in wetlands was <br />based on the "National List of Plant Species that Occur in Wetlands: Intermountain (Region 8)" <br />(U.S. Fish and Wildlife Service, May 1988). Soil colors were determined using Munsell Soil <br />Color Charts. Indicators of hydrology include direct observations of ponding or soil saturation, <br />and indirect indicators such as the presence of drift lines, scour lines, sediment deposits, and <br />water marks. Observations were recorded on Wetland Determination Data Forms (WDDFs), <br />and photographs were taken to document conditions. <br />Active channels and ponds /lakes may also be regulated under Section 404. For channels to be <br />regulated, they must have perennial flow or flow relatively frequently. The ordinary high water <br />mark (OHWM) is the limit of jurisdiction of channels and ponds /lakes. Swales and erosional <br />features characterized by infrequent, short duration and low volume flow are not regulated. <br />Ditches excavated in uplands are also not regulated. <br />Relevant features were recorded with a mapping -grade GPS. Digital aerial photographs (U.S. <br />Department of Agriculture, summer 2005) were used for figures. <br />Lastly, the results of the fieldwork were evaluated in the context of the December 2008 guidance <br />on CWA jurisdiction per the U.S. Supreme Court decision in the Rapanos and Carabell cases. <br />4.0 RESULTS <br />Delineation of Potential Wetlands for Mine Life Extension 2 Project <br />Cripple Creek & Victor Gold Mining Company <br />Representative photographs are included in Appendix A and WDDFs are included in Appendix <br />B. In summary, no wetlands or other waters regulated under Section 404 were found in any of <br />the study areas. The lack of these features is due to the relatively small watersheds, well - <br />drained soils, steep slopes, and only moderate precipitation of the study areas. The following <br />provides a description of each area. <br />4.1 LOWER SQUAW GULCH <br />Figure 3 shows the features of Squaw Gulch and the locations of WDDFs completed and <br />photographs taken. <br />Squaw Gulch downstream of State Highway (SH) 67 has been observed and wetlands <br />delineated by the principal investigator in past years, including in 1991, 1997, 1998, 1999, and <br />2005. This work was completed for various purposes. The most recent delineation, completed <br />in August 2005, was provided to the Corps and was approved by them per letter dated July 20, <br />July 2011 Bikis Water Consultants, LLC Page 3 <br />
