The least cost type of pipe material <br />for the various diameters is reflected in the estimate. Pipeline <br />costs have been compared with pipeline cost estimates from the united <br />States Bureau of Reclamation (USBR) Dolores Project as well as the <br />Animas-La Plata Definite Plan Report. Installed estimated pipeline <br />costs are shown in Table 0.1. <br /> <br />0.3.4 River Diversion Structures <br /> <br />River diversion structures were included for parcels over 30 acres. <br /> <br />The diversion structure would be constructed across the river to form <br /> <br /> <br />a pool of water with sufficient depth for the pump to draw from. A <br /> <br /> <br />weir type diversion structure consists of a 4 foot high wall with a <br /> <br /> <br />footing and riprap on each side for stability and protection from ice <br /> <br /> <br />damage. The estimated cost of the structure is $210 per foot. The <br /> <br /> <br />diversion structure was estimated to be 50 feet long for the McElmo <br /> <br /> <br />Creek. <br /> <br />It may not be practical to build a massive diversion to serve a small <br />parcel. A farmer farming a small parcel with low flow requirements <br />would probably have a simple temporary diversion which could be <br />nothing more than a berm graded across the river with a backhoe or <br />dozer to form a shallow pool for his pump to take suction from if <br />flows in the stream are low. If stream flows were too large to allow <br /> <br />5 <br />
