<br />II. BACKWATER PROFILE ANALYSIS <br />A. Specific Reach Descrip!j~~~~~ness Coefficients, Debris <br />Blockage Potential <br />1. Cedar Creek <br />From the upstream study limit near the Fairview Water <br />Treatment plant (station 611+30), Cedar Creek flows generally westward, <br />crossed by a local road and Highway 50. The local road crossing is a <br />96 inch diameter CMP culvert. A 78 foot span bridge with 2 piers is <br />the Highway 50 crossing. The channel in this reach is a moderately <br />irregular section in clay soil. The overbank area is covered on both <br />sides with grasses, weeds, and stiff brL'sh which occasionally extends <br />out over the main channel. Manning roughness coefficients of ..04!i and <br />.055 have been assigned the main channel and overbank areas, respec' <br />tively. <br />From the Highway 50 crossing near Fainiew, Cedar Creek flows <br />toward the City of Montrose, with Highway 50 crossing twice mor'e before <br />reaching N. 2nd Street in Montrose. A sma', 1 intermediate tributary <br />joins Cedar Creek near station 550+50, and the AM lateral ditch ter- <br />minates at the watercourse at station 561+50. <br />Cedar Creek is crossed near station 504+00 by Highway 50, a 82 <br />foot bridge with two piers. County Road 6700 is crossed near station <br />432+00 in a wood plank box culvert with wingwalls. The Loutenhizer <br />Canal crosses Cedar Creek in an overhead fl ume with two piers near sta- <br />tion 380+00. Immediately downstream of the canal f'lume near the ceme- <br />tery, a wooden bridge al so crosseS the str'eam. Cedar Creek crosses <br />Hillcrest Drive near station 345+00 in a 120 inch diameter CMP whose <br />projecting ends are somewhat mitered to RBtch the steep bank slope. <br /> <br />5 <br />
