rose and spilled over the designed berm spillway, until it undercut the structure, the weight of which simply fell into the waters and was pushed into the pit and covered by flood born debris and related native berm materials. The residual bottom was not a temporary berm as stated in the OMLR inspection report, but as identified properly during the inspection, the underlying native materials of the native berm itself. Also contrary to the OMLR statement that the operation allowed the water in, it is in fact designed to purposefully direct flood flows into the basins. The only effect of the loss of the sill was to dramatically drop flood flows in half for nearly a 12 hour period, to the direct benefit of downstream users. The need to simply restore the spillway with earth is that it is considerably more cost effective and beneficial to all to do so. That the people responsible for creating the map are unconcerned by the proposal, we understand that you would want those responsible for the enforcement of it to concur, and as soon as that concurrence is met, we will forward it to the OMLR to conclude the Technical Revision necessary to allow the repair to be completed according to the specific requirements and limitations described in the A.C.E. correspondence. We would hope to have this resolved and approved in time to prevent further intrusion into our basin before spring flooding. We trust our reply adequately addresses the concerns of the Office. Naturally, should you require further clarification or additional information, we look forward to working with you. Thank -you again for your cooperation and kind assistance.
