<br />below. This reach of channel has been assigned a main channel rough- <br />ness coefficient of .060, while that of the overbank areas is set at <br />.080. <br /> <br />Between Otter Road and its confl uence with the Uncompahgre Ri ver, <br />Ory Cedar is crossed by the Loutsenhizer Canal, Woodgate Road, and <br />Highway 550. The Loutsenhizer Canal crossing, like that of Cedar <br />Creek, is a flume supported by two piers above the stream bed. At <br />Woodgate Road, a steel truss bridge spanning the stream is provided. <br />The bridge deck is 16.5 feet above the channel invert, and the span is <br />approximately 36 feet. A steel pipe also crosses the stream at this <br />point at a comparable height above the streambed. At Highway 550, a <br />bridge with two piers is the crossing structure. The bridge deck is <br />set 21.5 feet above the streambed, and the span is 64 feet. Just <br />downstream of the bridge, an irrigation flwne also crosses over the <br />stream, bei ng supported by steel beam pi ers and at aprox imate 1 y the <br />same distance above the stream as the Highway 550 bridge deck. <br />Approximately 2,500 feet downstream of High~lay 550, Dry Cedar <br />Creek joins the Uncompahgre River. <br />The Otter Road to the confluence reach of Dry Cedar Creek is <br />typified by moderately irregular channel sections, 'flith minor to <br />moderate meandering. Overbank growth is dense though not as signifi- <br />cant as upstream of Otter Road. Roughness coefficients assigned the <br />stream in this reach are .045 for the main channel and .060 for the <br />overbank areas. <br />The debris potential of this stream is particularly severe. <br />Debris is generated in the upper reaches of the stream as a byproduct <br />of sheep grazing and from the dense vegetation growing alongside the <br />channel. Dried sagebrush as well as juniper and cedar accumulate along <br /> <br />12 <br />
