The Trinchera Irrigation Company <br />began the removal of the riprap from the face of the dam. Gardner Excavating, Inc., the <br />general contractor, began the removal of silt, crushing riprap, and making necessary <br />preparations for reconstruction which would begin as soon as approval from the State <br />Engineer was received. <br />On November 2, 2009 approval of the design plans was received from Paul Perri, P.E. <br />with the State Engineer's Dam Safety Division. Reconstruction began immediately. <br />Photographs of the repairs and reconstruction are included in Appendix G. <br />The slope on the upstream side of the dam, replacement of the rip rap, and the outlet pipe <br />extension should be completed by the early December 2009.
