• sediment control ponds. Transpiration losses are considered to be negligible. <br />The maximum (righted) rate of water withdrawal from the production cell is 0.33 <br />cfs. Assuming that water is pumped for eight hours per day, five days a week, for <br />50 weeks each year, approximately 54.5 ec, ft. would be removed from the Yampa <br />River alluvium on an annual basis. This is an extreme pumping scenario since <br />water usage at the loadout consists only of bathhouse consumption, dust <br />suppression, end wash-down water. <br />Consumptive use at the sediment ponds is calculated on the basis of lake <br />evaporation. Estimated annual evaporation from the pond water surface is 1.9 <br />acre-feet. Table 21-1 shows the derivation of this figure. This figure is a <br />worst case estimate because it assumes the ponds are aLuays full. <br />The previously outlined procedures will be implemented to minimize disturbances and adverse <br />impacts on fish and wildlife and related environmental values during and after operation of <br />the loadout facility. Enhancement of these resources will be achieved following reclamation <br />. of the facility by restoring the approximate original contour of the land, removal of all <br />structures and barriers (fences and rail lines), and timely revegetation with species <br />compatible with the post-operational land use. Displaced species which have the capacity to <br />exploit the habitat created by reclamation activities will utilize developing reclaimed <br />areas. Additional enhancement activities are considered to be infeasible or impractical due <br />to the limited size of the disturbance area, its configuration, and surrounding land use <br />activities. <br />Literature Cited <br />Cowardin, L.M., V.
