This dam diverts about 11,000 acre-feet <br />of water annually to 3,547 acres of farm land owned by the Beeman <br />Irrigation Ditch and Milling Company and the Meadow-Island Ditch <br />Company No.2. <br /> <br />PROBLEM <br /> <br />The existing diversion dam was built of wood in the 1880's. <br />It has deteriorated to the point that it could collapse when as <br />little as a 5-year frequency flow occurred in the South Platte <br />River. Loss of this dam would force the irrigators to use well <br />water for their supply. It is estimated that the use of well <br />water would increase the cost of irrigation by approximately $50 <br />per acre. Furthermore, 20 percent of the land currently <br />irrigated cannot be served by wells. This acreage would revert <br />to dry land farming and crop production would be significantly <br />reduced. <br /> <br />CURRENT STATUS <br /> <br />In November, 1980, the Beeman Irrigation Ditch and Milling <br />Company and the Meadow Island Ditch Company No. 2 jointly submit- <br />ted an application to the CWCB for assistance in replacing their <br />diversion dam on the South platte River. Subsequently, and <br />through joint funding by the Board and the companies, a feasi- <br />bility study was completed by Howard Noble & Associates, an <br />engineering firm in Wheat Ridge, Colorado. Several alternate <br />designs were considered by the engineer for this project. <br /> <br />PROPOSED PROJECT <br /> <br />The project as proposed by the engineer would replace the <br />existing wooden diversion dam with a reinforced concrete <br />structure. The new structure would utilize the same design <br />concept as the old one except for the materials specified. The <br />new structure will improve operation safety, make maintenance <br />easier, and perform all of the other functions of the existing <br />dam. The estimated cost of this project is $220,000. The <br />benefit/cost ratio is 2.4:1. <br /> <br />Revised 2/25/82 <br />
