<br />PROJECT SUMMARY <br /> <br />This project proposes to rebuild the Beaman-Meadow Island No.2 main <br />Diversion Dam located on the South Platte River. The dam site is approximately <br />3 miles Southwest of Platteville, Colorado in Weld County. This Dam provides <br />irrigation water to 3,547 acres of farm land and has annual average water <br />diversion of approximately 11,000 acre-feet. <br />The existing dam was built of wood in the 1880's and is in such poor <br />condition that it will probably last no more than 2-3 years. There is no way <br />to deliver irrigation water to the District's lands without this dam. It is <br />proposed to replace this structure with a concrete overflow dam using stop <br />logs to provide the necessary head to feed the canal headgates. Total depth <br />of water upstream of the dam would increase no more than 3 feet with the <br />flash boards in. a cutoff wall of steel sheetpiling under the concrete floor <br />will act as the foundation and eliminate any possibility of piping under <br />the structure. The project costs are estimated to be $216,770.00 if construc- <br />tion begi ns in 1 982. Other alternati ves cons idered were an Ogee Cres t concrete <br />dam and a Radial Gated concrete structure. These were not chosen because <br />operating and maintenance expense would be double and the project costs <br />would also be increased by 50 to 100%. <br /> <br />-1- <br />
