G-30 Page 2 of 3 Keenesburg Project RETTEW Project No.114782000 October 16,2019 Attachment B.Representative site photographs are provided in Attachment C.Sampling point and photograph locations are noted on Figure 2,Attachment A. Streams One low-gradient drainage runs along the east edge of Sections 1 and 12,T2N-R64W. This mapped drainage is identified as Ennis Draw on the USGS topographic quadrangle presented in Attachment A,Figure 1,and is depicted with a dashed blue line signifying an intermittent/ephemeral stream. It is also identified on the aerial basemap provided in Attachment A, Figure 2. Wetlands containing ponded water, hydrophytic vegetation, salt-covered and/or sparsely vegetated depressions,and saturated soils were observed within portions of this drainage during the field investigation.Photographs of these features are provided in Attachment C. Although Ennis Draw is depicted as a continuous dashed line on the USGS topographic map through the entire AOI, most of the north half of the drainage lacked evidence of a stream channel and a defined bed and bank. Some portions contained completely vegetated uplands with no signs of a defined channel.The south half of the drainage contained a network of inundated depressions. It appears that surface water only collects within portions of the drainage, with some of the surface water remaining year-round and some remaining only seasonally.No flowing water was observed anywhere within Ennis Draw.The USGS mapped drainage for Ennis Draw terminates in uplands approximately three miles north of the project area in the northeast quarter of Section 30,T3N-R63W with no visible downstream connection to any surface waters. Wetlands A total of 25 palustrine emergent(PEM)wetlands were documented within and adjacent to Ennis Draw. Some of these PEM wetlands contained open water in their centers and had palustrine unconsolidated bottom(PUB) wetland components to them.These wetlands are depicted on Attachment A,Figure 2. Eight sampling points were assessed to document wetland conditions in the AOI. Please refer to Table 1 for a list of the wetlands present within the AOL For more information regarding the wetlands, please refer to the Wetland Determination Data Forms provided in Attachment B.
