RAG TMCC Fish Creek 2003: Wetland Delineation Report <br />. Project A -Bleeder Shaft and Access Road <br />Location/Site Context <br /> <br />The proposed bleeder shaft and access road are located primarily in Section 11, of <br />Township 5 North, Range 86 West, in Routt County Colorado (Map 2), The proposed <br />shaft pad is 280 by 280 feet surrounded by a 500-foot wide disturbance zone. The access <br />road is approximately 7,1141ineal feet from start to end point. A 100-foot wide corridor <br />was surveyed along the entire length of the proposed access road corridor at a width of 50 <br />feet perpendicular from each side of the centerline. Wetlands located within the project <br />azea are located east of the access road at its starting point, and in the vicinity of the <br />proposed sha8 pad. Aside from these azeas the project is located within upland grass and <br />shrub plant communities. <br />Wetland Description and'Justification <br />A stock pond and a drainage Swale are located immediately east of the proposed access <br />road at its starting point (Photos 1 & 2, Map 2). The stock pond has been constructed in <br />an intermittent channel indicated by a dashed blue line on the USGS topographic map of <br />the azea. A Swale dominated by hydrophytic vegetation is situated upstream of the pond. <br />The swale is approximately 500 feet long with a groundwater seep located at the upward <br />limit of the wetland azea. This seep provides hydrologic support for the wetland and stock <br />• pond while maintaining hydrophytic vegetation and hydric soil conditions down-gradient <br />from the seep within the confines of the drainage Swale. Up-gradient from the seep the <br />Swale is dominated by upland vegetation. The pond is classified as a lacustrine deep <br />water habitat with an unconsolidated mud bottom. The Swale and perimeter vegetation <br />around the pond aze classified as palustrine emergent wet meadow. There are small <br />patches of emergent marsh vegetation azound the perimeter of the pond. <br />Fish Creek is a lower perennial riverine system with defined bed and bank and an <br />unconsolidated gravel Coble bottom (Photos 3 & 4). The banks of the creek channel <br />slope steeply and provide limited area for the growth of wet meadow wetlands. The <br />creek is subject to periodic flooding by storm water runoff and seasonal snowmelt. No <br />aquatic bed is present and a nominal amount of emergent marsh wetland may be found <br />where scour does not preclude growth of this vegetation community. There is a narrow <br />band of persistent emergent wetland along the banks no more than a few feet wide. The <br />landward limit of this wetland type was used to define the jurisdictional limits of the <br />primary channel (Map 2). Flood plain is virtually non existent on the north side of the <br />channel being confined by sandstone outcrops. <br />No attempt was made to delineate wetlands in the flood plain on the south side of the <br />primary channel as potential disturbance is to be limited to the north side. Casual <br />observation of this azea indicates portions would likely qualify as wetland using the <br />Cowazdin System; however the majority of this area would most likely not meet the soil <br />and hydrology pazameters applied by the COE. <br />Habitat Management, Inc. 2 01/06/03 <br />
