Summary habitat, roads and the railroad, farmsteads and the town of Ovid, Colorado. The town of Ovid is to be protected from the 100-year frequency. storm event. Level of protection to the remaining flood plain varies from a 50-year level at the floodwater retarding structures to a 5-year level at Highway 138. Consideration will be given to measures that create, preserve and enhance watershed values for wildlife and natural beauty and to measures that reduce environmental pollution. . " Works of Improvement to be Installed The project measures include a program of land treatment and structural measures with a total project cost of $4,316,170. Public Law 566 funds are to provide $3,150,200 and other funds are to provide $1,165,970. The project.is to be constructed over a 5-year installation period. LAND TREATMENT MEASURES Land treatment measures to be applied include practices for watershed protection, fire control -intensification, land and vegetative improve- ment, tree plantings for windbreaks and wildlife food and shelter, irrigation water management and wildlife habitat management and enhance- ment. Land treatment measures will be established by the landowners and operators on private and state land in cooperation with.the Soil Conserva- tion and Natural Resources Districts, the Colorado Division of Wi ldl ife and-;-tohe-5-t-a-te-Foresle". ~ --------- -- ----- - - ----- Costs for the land treatment measures are estimated at $902,150 which will be provided by funds other than P.L. 566 funds, except for $1,500 of P.L. 566 funds for accelerated technical assistance to Colorado rural fire districts. STRUCTURAL MEASURES The structural measures included in the plan consist of 10 single pur- pose floodwater retarding structures, three grade stabilization struc- tures, three f100dways and 10 canal inlet structures. The floodwater retarding structures have combined capacities of 5,731 acre-feet for floodwater detention and sediment accumulation and are designed as dry dams. The combined length of the three floodways is about 7.9 mi les. The present flow condition of the floodways is ephemeral. One and two- tenths miles of floodways have no or practically no defined channel. The remaining reaches are manmade or previously modified channels with an approxImate construction date of 1910.. The land use adjacent to the floodways is agricultural. The crops grown are sugar beets, corn, beans, and alfalfa. 3
