<br />Need for the Project <br /> <br />~ <br /> <br />The SIC is undertaking repairs to their headgate and diversion <br />structures to ensure that it can continue to divert water from <br />the South Platte River. The current facility has three major <br />components. They are the ditch intake, the concrete diversion <br />wall, and a sand dam. The ditch intake is a concrete structure <br />using a board system for adjusting flows into the ditch. This <br />structure is in deteriorated condition due primarily to its age. <br />The concrete diversion wall is a 4 ft high and 200 ft long wall <br />located in the river channel used to divert flow into the ditch. <br />This structure is also in deteriorated condition. At times of low <br />river flow, a sand dam is pushed into position to divert water <br />into the canal. At times when short periods of high flow exists, <br />the sand dam is washed away creating a water shortage in the <br />canal and the need to push a new sand dam into position when the <br />river flows allow. Most recently this type of damaging event <br />occurred in 1995 and 1997. Additional problems do occur with the <br />existing structure, they include sand plugging the ditch and <br />debris, mainly trees, hangs up on the diversion.
