<br />.1 <br /> <br />Hypothetical Scenario #2 <br />The Upper Pretty River Water Conservation District desires to obtain an RICD water <br />right for a whitewater boating course. The proposed boating course length is 1,000 <br />feet, and the hydraulic drop within that reach is 5 feet. The requested RICD flow rate <br />is 1500 cfs. <br /> <br />Evaluation <br />The average stream slope = 5'/1,000' = 0.005 ftlft <br />The requested flow rate = 1,500 cfs. <br />The PI = (0.005 x 1500) x 100 = 750 <br /> <br />Based on a PI of 750, the proposed reach may be appropriate for the requested <br />RICD since the PI exceeds the minimum threshold of 75. However, the <br />requested flow rate exceeds the CWCB's upper range flow rate of 350 cfs, and <br />may therefore not efficiently utilize the flow rate. <br /> <br />Alternatively, the Applicant could evaluate what minimum flow rate would be <br />required for this reach in order to meet the minimum PI and then compare it to <br />the range of flow rates suggested by CWCB, <br /> <br />eJ PI =75 <br />Slope = 5'/1000' = 0.005 ftlft <br />Solving; Flow rate = 75/10010.005 = 150 cfs. <br /> <br />Therefore, an application can be prepared that would be within the eWCB's <br />target flow range for the stream reach in this scenario for whitewater boating. <br /> <br />Hypothetical Scenario #3 <br />The City of Flatland desires to obtain an RICD water right for a whitewater boating <br />course. The proposed boating course length is 1,200 feet, and the hydraulic drop within <br />that reach is 3 feet. The requested RICD flow rate is 150 cfs. <br /> <br />Evaluation <br />The average stream slope = 3'/1,200' = 0.0025 ftlft <br />The requested flow rate = 150 cfs. <br />The PI = (0.0025 x 150) x 100 = 37.5 <br /> <br />Based on a PI of 37.5, it would appear that the proposed reach is not appropriate <br />for the requested RICD for whitewater boating since the PI is less than the <br /> <br />JO <br />
