<br />ALTERNATIVE 7 <br />STORAGE OF LOWER <br />TRIBUT ARY FLOWS <br /> <br />This alternative considers reservoir <br />sites on East Bijou, West Bijou, <br />Muddy Creek and Wildcat Creek, <br />East Bijou and West Bijou Reservoirs <br />were each sized with a storage capac- <br />ity of approximately 9,000 acre, feet. A <br />reservoir with a total capacity of about <br />4,000 acre, feet was sized for Muddy <br />Creek. Storage in these three reser- <br />voirs would provide deliveries of an <br />estimated annual 1,550 acre-feet of <br />water, Wildcat Reservoir (Alternative <br />6) was resized with a total capacity of <br />22,000 acre-feet to store only flows <br />from Wildcat Creek. An estimated <br />1.550 acre-feet of water could be deli- <br />vered annually from Wildcat Reser- <br />VOiL Total deliveries from the four <br />reservoirs would be 3,100 acre-feet. <br /> <br />Evaluation <br /> <br />The market-valued outputs of this <br />alternative would be irrigation water. <br />Net annual economic benefits are esti- <br />mated to be $30.0 thousand, This <br />amounts to a 0,1 percent rate of return <br />on the required investment of $29 <br />million. <br /> <br />The construction of any of these sma]) <br />off-mainstem storage facilities would <br />probably cause short-term employ- <br />ment changes in the central plains <br />zone, especially during construction, <br />Government and services could be <br />temporarily taxed by the influx of con- <br />struction personnel. <br /> <br />None of these reservoirs has been <br />sized to provide flood control storage. <br />Over time, these tributary reservoirs <br />would tend to trap significant amounts <br />of sediment which would tend to <br />reduce available water storage capac- <br />ity if reservoir dredging were not <br />performed, <br /> <br />8 <br /> <br />I ,,( <br />~ I <br />!-~~_rnL__ <br />I JACKSON "~o BALZAC <br />RF~ ~"V . <br />ERSIO[ P , <br />,(5, ' t:' ) <br /><b~Clt.i.~~~ "WE L[O~).. 0.. <br />E;~,:' <) ((' >-. fl "OOGA( <br />1 " /. <br />r \ ( z <br />\ <br />rI-: .~ ~ <br />:, If : ~UDDY c~~ J <br />~/ (7) 1.~7' , $1- \ <br />l/1. !7,.i' 1\ <br />I ~AS~ B,i~u f ( / <br />W~~1J~_(;d <br />( f <br /> <br /> <br />. <br /> <br />'1 <br /> <br />r--' <br /> <br />" <br /> <br /> <br />t--- <br />I <br />I <br />
