<br />HUMAN/ECONOMICS - The profitability of the irrigated cropland will decrease as costs ~ <br />of diversion increase. <br /> <br />This alternative is not desirable to the agricultural producers within the project area. <br /> <br />HAYDEN DIVERSION/DITCH AGGREGATION (Alternative 1) <br /> <br />This alternative constructs a single diversion out of the Yampa River for five current <br />irrigation ditches. It would be located at Mt. Harris (an old coal mining town). Several <br />ditches would be combined. Those ditches involved are the Gibralter, Marshal Roberts, <br />Williams, Walker, and Shf?lton. The Gibralter is on the north side of the river while the <br />others take water out on the south side. <br /> <br />Components: <br /> <br />The following list of major component extents are preliminary estimates. (1-D,iver~ion, <br />7300 ft of new ditch, 1800 ft. of concrete lined ditch, 23,800 ft. of ditch enlargement _ <br />capacities up to 138'cfs:)ln addition to these improvements there would be a need for <br />several railroad/road crossings, utility crossings, and water control structures. <br /> <br />1J Costs: $2,982,000 <br /> <br />Effects: <br /> <br />SOIL RESOURCE - There will be streambank disturbance in the areas were <br />construction will oc~ur however)l$. it will be a short term effect. Streambed disturbance <br />during annual diversion construction will be eliminated with project. With better control <br />of the diversion greater streambank stability is expected. <br /> <br />SURFACE WATER - Some of the existing diversion points will be abandoned as a <br />result of constructing the one new diversion to replace them. This will reduce sediment <br />loading from maintenance activities associated with the old diversions. The new <br />turnouts proposed will reduce sediment loading associated with their operation. <br /> <br />WETLANDS - Some areas may receive less water as a result of moving or eliminating <br />portions of the five ditches involved in the project. Other areas may receive more water <br />as a result of increased seepage from combined ditches. No net change in <br />acreage/functions or values i~ expected. <br /> <br />WATER QUANTITY - With the planned system improvements in place there will not be <br />a problem being able to divert the agricultural producers decreed water. The improved <br />system will also eliminate some seepage losses presently occurring. <br /> <br />PLANTS/RIPARIAN HABITAT - Some habitat will be destroyed during construction but <br />most of it will return. The habitat which exists along abandoned portions of canal will <br />probably be lost over time. <br /> <br />ANIMALS/ENDANGERED SPECIES - It is not known how project action will impact the <br />habitat or population of endangered fish. It is assumed that the project will have <br /> <br />Hayden 14 <br />
