We have completed our review of the design and construction documents and have found <br />them to be acceptable for construction. The coffer dam and temporary outlet works will allow <br />surface diversions to be routed through the reservoir basin and existing outlet works to irrigated <br />lands below. It will, also, be used for protection during the planned future Model Dam outlet <br />works replacement and embankment repair. <br /> <br />We look forward to working with you on this construction project and to achieving the <br />successful future completion of the proposed modifications to Model Dam and appurtenant <br />structures. <br /> <br />Sincerely, <br /> <br />c-~~~ <br />~;~ ~yers, P~E. <br />Assistant State Engineer <br /> <br />Xc: <br /> <br />Dam Safety Central File <br />Steve Witte, Division Engineer <br />Mike Graber, Dam Safety Engineer (w/approved plans and specifications) <br />William Green, Water Conservation Board <br />Danny Marques, Water Commissioner <br />R.B.
