<br />2. Do remedial work only to the extent that the diversion <br />is put back into normal operation: <br /> <br />This alternative would be an immediate fix to any problem. <br />Remedial activities would produce results with varying <br />design life ranging from a few months to a few years. At <br />times of failure, the ditch is out of service resulting in a <br />potential loss of water to the district. Remedial activities <br />of this nature are impossible to budget for and create an <br />extreme hardship on Bijou. Remedial activities do not fully <br />address the problem with the huge sand bar formed upstream <br />from the diversion. The sand bar in part causes the failure <br />of the river diversion and creates the need for remedial <br />activities. Continuing to perform remedial activities is no <br />longer acceptable to Bijou. <br /> <br />3. Replace 96 feet of the river diversion structure with a <br />new bladder gate system and continue to use the existing <br />intake gates: <br /> <br />This alternative would consist of replacing part of the <br />river diversion only. A 96 foot section of inflatable <br />bladder gate would replace the slide gate and part of the <br />current board system. The remaining diversion will be left <br />intact. The ditch intake structure would also remain <br />untouched. This alternative would solve problems associated <br />with the current operational status of the diversion. <br />Lowering the bladder gate during times of high river flow <br />will greatly reduce the "wear and tear" on the entire intake <br />system. This structure will greatly reduce the sand bar <br />which forms upstream from the current diversion thus <br />reducing the sanding problem in the ditch. The bladder gate <br />will also alleviate the problem of debris hanging up on the <br />structure. The cost of this alternative is approximately <br />$840,000. <br /> <br />4. Replace 192 feet of the river diversion structure with a <br />new bladder gate system and continue to use the existing <br />intake gates: <br /> <br />This alternative completes the provisions of alternative <br />number 3 but increases the length of the bladder gate to 192 <br />feet. The increased length of bladder gate would completely <br />alleviate the problems associated with the sand bar and <br />greatly reduce the sanding problem in the ditch. The cost of <br />this alternative is approximately $1,596,000. <br /> <br />Feasibility Study <br />Bijou Irrigation Company <br />Diversion Structure <br />June 2007 <br /> <br />3 <br />
