G-3 <br /> delineation procedures followed the protocol established within the 2012"Regional Supplement to the <br /> Corps of Engineers Wetland Delineation Manual: Great Plains Region (Version 2.0) and the 1987 <br /> Corps of Engineers Wetland Delineation Manual. The approach recognizes the three parameters of <br /> hydrology,vegetation,and soils to identify and delineate wetland boundaries. Representative sampling <br /> points were selected to characterize habitat and plant communities;and,defined bed and bank features <br /> were used as criteria to identify streams. Aquatic resources that were identified in the field were <br /> mapped utilizing a GPS unit with sub-meter accuracy. In addition,several National Wetlands Inventory <br /> (NWI) mapped wetlands are located within and adjacent to Ennis Draw within the subject corridor; <br /> these areas were field-verified. <br /> Notable findings are described as follows: <br /> Stream Features—one low-gradient drainage runs along the east edge of Sections 12 and 1,respectively. <br /> Wetlands consisting of ponded water, hydrophytic vegetation, salt-covered and/or sparsely vegetated <br /> depressions, and saturated soils were observed present within this drainage. USGS topographic <br /> mapping depicts this drainage feature with a dashed blue line,indicative of an intermittent or ephemeral <br /> "stream"; however,the north one-half of this so-depicted feature lacked evidence of a stream channel <br /> and/or a defined bed and bank. Portions contained completely vegetated uplands with no signs of a <br /> defined channel. <br /> The south one-half of the drainage contained a network of inundated depressions. While no flowing <br /> water was observed anywhere within Ennis Draw during any of three field investigations (December <br /> 2019; April 2019; and, September 2019, respectively), it is apparent that surface water collects only <br /> within certain portions of the drainage, with some features remaining present year-round and others <br /> only seasonally. The USGS-mapped drainage(Ennis Draw)terminates in uplands approximately three <br /> miles north of the Permit Area (more specifically, within the extreme NW1/4 of Section 30; T3N; <br /> R63W),with no visible downstream connection to any surface waters. <br /> Wetlands — a total of twenty-five (25) palustrine emergent ("PEM") wetlands (inclusive of those <br /> features cited above)were documented within and adjacent to Ennis Draw. Some contained open water <br /> in their centers and had palustrine unconsolidated bottom(PUB)wetland components to them. Each <br /> feature was assigned an identifying number(for future reference),and the approximate areal extent was <br /> field-determined, as shown in Table Gl: Summary Listing of PEM Wetlands—Ennis Draw.
