The poorly consolidated upper embankment <br />soils of the dam were repaired by raising and re-consolidating the dam crest. <br />The lower reaches of the outlet works were leaking badly and in poor repair. Re- <br />constructing this portion of the outlet works relieved significant erosion dO\\TIstream of the <br />reserVOIT. <br /> <br />I <br />I <br /> <br />I <br />I <br /> <br />Proiect Data <br /> <br />Sponsor: Trinchera Irrigation Company <br /> <br />Count~.: Costilla <br /> <br />Rinr-: T rinchera Creek <br /> <br />I <br />I <br /> <br />Ter-ms of Loan: 5980.675 @ 1% for 40 years <br /> <br />Annual Payment: 529,871 <br /> <br />Design F.ngineer-: Smith Geotechnical Consultants.
