Table 11 presents the wetland and channel characteristics as well as the dominant vegetation <br />species at each "recorded" checkpoint along Jubb Creek and the West Fork of Jubb Creek beginning at <br />an artesian well approximately 5 miles above the point where the creek crosses County Road 32. The <br />upper mile of stream reach below this beginning point exhibited variable wetland widths from 0 to 2 feet <br />up to an expanded streamside wetland of 40 feet in width. Where a WUS was observable (less than 1/2 <br />of this reach), it averaged 1 foot in width otherwise wetland existed across the stream channel. The <br />channel, where it existed, was generally "V" shaped and had been excised between 0 and 6 feet into the <br />valley bottom. Immediately below this reach was wetland No. 5 (4.9 acres) that also exhibited one of the <br />highest quality stock tanks in the study area (from a wildlife habitat perspective). This stock tank <br />exhibited a reasonably sized area of open water, emergent vegetation (Schoenoplectus lacustris) along <br />the wide dam, and extensive wetland meadow vegetation along the perimeter that merged with wetland <br />No. 5. <br />Over the next 1000 feet of stream reach (immediately below Wetland No. 5), the wetland / stream <br />system becomes rather complex. Through this area, are intermittent flat channels that exhibit wetland <br />vegetation, interspersed with sections where no discernible channels are present. It is presumed that <br />streamflow through this reach is largely subterranean at a depth sufficient to allow upland plants to <br />become dominant at the surface. <br />Finally, below this complex reach for a distance of 3.5 miles (until Co. Rd. 32 is encountered), the <br />stream systems exhibits expanded streamside wetlands with no discernible WUS channel bottom (grass <br />lined). The flood channel forms a "U" or deep "U" shape that exhibits incision from 2 to 30 feet with one <br />section of almost 2 miles where the incision averages 20 to 30 feet. The wetland width ranges from 6 to <br />25 feet in width but averages 12 to 15 feet. Dominant vegetation along this "recorded" checkpoint reach <br />of Jubb Creek included: Carex aquatilis, Cirsium arvense, Juncus balticus, and Agrostis a/ba, as well as <br />several additional sub-dominant taxa. <br />Table 12 presents the wetland and channel characteristics as well as the dominant vegetation <br />species at each "recorded" checkpoint on the portion of Wilson Creek that intercepts the study area <br />boundary for a distance of approximately 2 miles (the survey went 0.3 miles past the lower boundary and <br />an unknown (but minor) distance above the upper boundary). The entire length of this reach exhibits a <br />wide "expanded" streamside wetland and a WUS channel bottom averaging 4 feet in width. The depth of <br />incision ranges from 15 to 35 feet throughout the majority of this stream reach, except for a point <br />immediately above a road crossing that is just above cultivated fields where the channel exhibits a normal <br />shape with a depth of from 3 to 5 feet. The cross-sectional shape of the channel through this reach is a <br />deep "U". Dominant vegetation along this "recorded" checkpoint reach of Wilson Creek included: Typha <br />C MIMARCMIEKASSOCVAV29, INC. Page 12 Colowyo Coal Co. - Collom Project Wetlands
