For <br />construction purposes, access to the right-of-way of the buried lateral <br />systems would be generally adequate from existing roads. For operation <br />and maintenance purposes, about 63 miles of gravel-surfaced road would be <br />constructed for access to turnouts and valves. <br /> <br />In addition to the four gravity turnouts and three <br />pumping plants for irrigation, a wasteway turnout with a capacity of <br />about 700 cfs 'would be constructed from the canal to the La Plata River <br />so that water could be released when needed to satisfy project purposes <br />downstream; and another with a capacity of 30 cfs would be constructed <br />near the canal terminus to deliver municipal and industrial water to the <br />Ute Mountain Ute Indian Tribe. Water for rural municipal and industrial <br />users would be turned out near Breen, Colo.; treated at a proposed water <br />treatment plant to be constructed by the water users; and delivered by <br />pipeline to users. <br /> <br />(f) La Plata Diversion Dam <br /> <br />The La Plata Diversion Dam would be loc~ted on the <br />La Plata River about 1.5 miles from Breen, Colo., and would divert <br />riverflows by gravity to the Dry Side Canal. The diversion dam would <br />span the river and consist of a concrete overflow spillway 50 feet long <br />flanked by two compacted earth dikes that would form a pond immediately <br />upstream of about 7.5 surface acres with a maximum depth of 8.5 feet. <br />Approximately 1,300 cubic yards of concrete and 11,300 cubic yards <br />of riprap and compacted embankment material would be placed iri the <br />river. Diverted flows would be conveyed to the canal through a settling <br />basin and buried pipe inlet. Construction and operation access would <br />be from the canal O&M road. A des ign drawing of the dam is shown in <br />Attachment 5. <br /> <br />A-13 <br />
