Although it is feasible, it would continue to be a "sand pump", <br />susceptible to flood damage <br /> <br />4) To continue to try and use the structure "as is", with sand dams for river control. <br /> <br />This is a high risk option which is not recommended. In the event that a sand <br />dam was to blowout during spring runoff, it would be impossible to repair, <br />thereby losing the ability to divert water during the critical spring planting <br />season, The resulting crop losses could be catastrophic to shareholders. <br /> <br />The District's engineer, Zoyiopoulos and Associates, Inc. has provided technical <br /> <br />engineering assistance in the evaluation of the above alternatives, particularly concerning <br /> <br />the type and configuration of gate structures for headgate and diversion dams, <br /> <br />4 <br />
