RULE 2 PERMITS <br />These smaller streamside wetlands in the upper watersheds were typically measured as three to four feet <br />in width (both sides combined). Furthermore, the vegetation species observed along these reaches <br />typically exhibited dominance by Carex aqualitis, Agrosits alba, Rudbeckia laciniata, Juncus balticus, <br />and Prunus virginiana. Soils usually exhibited strong and abundant mottling and dark matrix colors <br />ranging from 10YR 2/1 to 10YR 3/2. Hydrology was provided by lateral saturation from stream flow. <br />These headwater streamside wetlands were mapped upgradient until they ended at their water source. <br />These water sources were often a series of old beaver ponds and/or seeps and springs. Occasionally, <br />these wetlands ended in a concave basin where overland flow no longer concentrated sufficiently to <br />saturate the ground for a long enough period to preclude upland vegetation. <br />Streamside wetlands (including "expanded" streamside wetlands) that were typically found lower in the <br />watershed were subjected to the more formal "recorded" checkpoints that were placed at systematic <br />intervals of 0.1 miles. The upper mile of stream reach below the beginning point for recorded <br />checkpoints on Collom Gulch exhibited an average wetland width of 4 feet. The channel was generally <br />trapezoidal in shape and had been excised between 5 and 10 feet into the valley bottom. Below this reach <br />for a distance of nearly 3/4 mile, the channel largely disappeared into "expanded" streamside wetlands as <br />well as larger wetlands 2 and 3 (8.13 acres). Over the next 1/2 mile, the stream reach was variable <br />between more narrow "expanded" streamside wetlands, and steep "V" shaped actively eroding channels <br />with only a foot of wetland. The final 1.5 miles of Collom Gulch (until Co. Rd. 32 was encountered) was <br />expanded streamside wetlands 10 to 40 feet in width along a very deeply incised channel. Dominant <br />vegetation along this "recorded" checkpoint reach of Collom Gulch included: Carex aquatilis, Agrostis <br />alba, Carex nebracensis, Cirsium arvense, and Acer negundo, as well as several additional sub - dominant <br />taxa. <br />• The upper mile of stream reach on the West Fork of Jubb Creek below the beginning point (Artesian <br />Well) exhibited variable wetland widths from 0 to 2 feet up to an expanded streamside wetland of 40 feet <br />in width. The channel, where it existed, was generally "V" shaped and had been excised between 0 and 6 <br />feet into the valley bottom. Immediately below this reach was wetland No. 5 (4.9 acres) that also <br />exhibited one of the highest quality stock tanks in the study area (from a wildlife habitat perspective). <br />This stock tank exhibited a reasonably sized area of open water, emergent vegetation (Schoenoplectus <br />lacustris) along the wide dam, and extensive wetland meadow vegetation along the perimeter that merged <br />with wetland No. 5. <br />Over the next 1000 feet of stream reach (immediately below Wetland No. 5), the wetland / stream system <br />becomes rather complex. Through this area, are intermittent flat channels that exhibit wetland vegetation, <br />interspersed with sections where no discernible channels are present. It is presumed that streamflow <br />through this reach is largely subterranean at a depth sufficient to allow upland plants to become dominant <br />at the surface. <br />Finally, below this complex reach for a distance of 3.5 miles (until Co. Rd. 32 is encountered), the stream <br />system exhibits expanded streamside wetlands. The flood channel forms a "U" or deep "U" shape that <br />exhibits incision from 2 to 30 feet with one section of almost 2 miles where the incision averages 20 to 30 <br />feet. The wetland width ranges from 6 to 25 feet but averages 12 to 15 feet. Dominant vegetation along <br />this "recorded" checkpoint reach of Jubb Creek included: Carex aquatilis, Cirsium arvense, Juncus <br />balticus, and Agrostis alba, as well as several additional sub - dominant taxa. <br />The entire length of Wilson Creek through the study area exhibits a wide "expanded" streamside wetland. <br />The depth of incision ranges from 15 to 35 feet throughout the majority of this stream reach, except for a <br />point immediately above a road crossing that is just above the cultivated fields where the channel exhibits <br />a normal shape with a depth of from 3 to 5 feet. The cross - sectional shape of the channel through this <br />reach is a deep "U ".
