<br />6.0 ~Ydroloqic and Hydraulic Analysis <br /> <br />The hydrologic values used for this feasibility <br />investigation were obtained from the Town's Flood Insurance <br />Study dated May, 1979. The Colorado Water Conservation Board <br />has reviewed the FEMA hydrologic analysis and finds the values <br />to be representative of existing basin hydrologic conditions. <br />The discharges were computed for two flow regimes through the <br />Town. These floodwater flow channels are known as "Spring <br />Creek Overflow" and "Spring Creek". Upstream of Rowe Avenue <br />and downstream of County Road No. 88. the stream will be known <br />as Spring Creek. For the stream reach between these two <br />east-west roads the Town's floodplain experiences divided <br />flow. The two stream courses are known as "Spring Creek <br />Overflow" (whiCh are the waters that flow southerly over U.S. <br />Highway 85 and west side of the Union Pacific Railroad) and <br />"Spring Creek" (which are the waters that flow through the U.S. <br />Highway 85 and Union Pacific Railroad bridges on the east side <br />of the Union Pacific Railroad tracks). The discharges in Table <br />I represent computations of split flow which occurs at the <br />intersection of Rowe Avenue and U.S. Highway 8~;, as well as <br />distribution of weir flow along the Union Pacific Railroad <br />tracks. <br /> <br />-5- <br />
