Because of this type of development, the initial dam <br />construction will be built to accommodate future raises to the maximum darn crest height. <br /> <br />The estimated time line for construction of the dam, based on the lead time necessary for <br />permitting, assumes that the dam and reservoir will be on line by 2005. <br /> <br />ANCILLARY FACILITIES <br /> <br />Beyond construction of the dam, there are several ancillary facilities that would need to be <br />constructed to make the Rueter-Hess Reservoir operational. In-priority Cherry Creek flows <br />can be captured and delivered to Rueter-Hess Reservoir via two means. The first would be <br />Rueter-Hess Reservoir Aqueduct No.1, which envisions a pipeline manifolded to several <br />alluvial wells completed along Cherry Creek in the reach that the District controls (from <br />Section 34 of Township 6 South, Range 66 West, to Section 9 of Township 6 South, Range <br />66 West). Creek elevations in this reach range from approximately 5,875 ft MSL at the <br />upstream end to 5,750 ft MSL at the downstream end of the reach. It is envisioned that the <br />alluvial well pumps would be sized such that the submersible pumps would be capable of <br />moving the water from the alluvial wells to Rueter-Hess Reservoir. <br /> <br />Rueter-Hess Reservoir Aqueduct NO.2 envisions a diversion structure on Cherry Creek in <br />Section 34 of Township 6 South, Range 66 West. This diversion structure would be located <br /> <br />5611i.rpt <br /> <br />-11- <br />
