The feasibility report is attached. <br /> <br />The feasibility study included detailed engineering work in the field and <br />office. Numerous alternative schemes were considered, five alternatives <br />were presented on plan and profile drawings, and two alternative plans were <br />selected and analyzed in detail. <br /> <br />The selected plans are Alternative Nos. 4 and 5, both of which by-pass the <br />dam on the west bank. Both alternatives are feasible to construct and <br />operate. Costs are similar. <br /> <br />Selection of the preferred alternative can proceed at this time on a basis <br />of non-engineering factors because both alternatives are similar in cost <br />and basic function. <br /> <br />Very truly yours, <br />WRIGHT WATER ENGINEE~~"ffl!fR~~ <br />~~~iG\STE4E:.. ~~ <br />~..... o...~.. <br />, I i \_~ <br />.:.. 3084 .! ! <br /> <br />...It= <br />.;c\ ~-';"I <br />-:-.8 ($..- <br />.r~S~O"AC ""0' ,,~ <br />7~l" .....u..~'t-v~.... <br />~ OF CU\.I),.... <br />~..," <br /> <br /> <br />By <br />Kenneth R. <br />Chief Engin <br /> <br />(UA.21) <br />831-036.080 <br />cc: Mr. N.C.
