<br />sources were inspected and evaluated to ascertain an opinion on the <br />extent and possibility for diverting flood waters into the City of <br />Bnlsh. <br />The USGS quadrangle maps show t:he ground topography east of <br />Badger Creek to slope towards the City of Brush, approximately 4.5 <br />miles east. As a result, there is concern for the possibility of <br />flood waters overtopping the channel banks in Badger Creek at the <br />Burlington Northern railroad and State Highway 6'-34 highway crossings and <br />for the flood waters to travel east to Brush. <br />Hydrologic calculations indicate the magnitude of the lOa-year <br />flood on Badger Creek to range between 25,000 cfs and 30,000 cfs. <br />Hydraulic computations show that the backwater effect created by <br />bot:h the railroad and highway embankments is sufficient .to overtop <br />the channel banks. However, the depth of wa t:er overtopping the <br />channel banks at either location is not sufficient to move t:he ex- <br />cess flood waters over the 4.5 miles of cultivated fields and <br />irrigation laterals and embankments and into Brush. Flooding, how- <br />ever, can be expected to occur for some distance east, of Badger <br />Creek along the railroad and highway. 'rhe worst situation is along <br />the railroad because of the higher embankment: and no provisions for <br />flows to overtop the embankment. <br />Flooding has been experienced in Brush due to overflows from <br />the Brush Lateral traversing through the west: and north portions <br />of the City. During the 1935 flood, mu.ch wat:erwas diverted from <br />Bi:jou Creek into the Upper Platte and Beaver Canal and thence into <br />the Brush Lat<~ral, only to spill wi thin t,he City of Brush causing <br />much damage and consternation. Since that'occu.rrence, an overflow <br />spillway has been constructed on thE' Upper Platte and Beaver Canal <br />at Badger Creek. This spillway will permit excess flood flows in <br />the canal to be spilled at a specified and safe location. <br />Storm runoff may still enter the lateral at many locations <br />within the City, reSUlting in possible overflow at other locations. <br />During periods of high rainfall and runoff, t:he City and local <br /> <br />-12-. <br />
