Once the preliminary design of the dam spillway and diversion structures is complete, <br />necessary permitting will be initiated. <br /> <br />PROPOSED DEVELOPMENT OF RESERVOIR <br /> <br />One of the attributes of the proposed Rueter-Hess Dam and Reservoir is that it can be <br />constructed solely to be a terminal storage structure for the District, or it can be expanded to <br />be a regional storage structure. In either case, water from various sources will be stored in the <br />reservoir and these supplies will then be managed to obtain increased utility of the resource. <br /> <br />The smaller Rueter-Hess Dam and Reservoir would be a 105-ft high dam, 2,000 it long, and <br />would inundate approximately 275 surface acres and would impound approximately 10,000 <br />ac-ft. Figure 2 shows the area of inundation. <br /> <br />If the Rueter-Hess Dam and Reservoir is built to its maximum capacity, it would be a 185-ft <br />high, 6,100-ft long dam, and would inundate a surface acreage of approximately 975 acres, <br />and would have a maximum storage volume of 55,000 ac-ft. Figure 3 shows the area of <br />inundation of this maximum reservoir. <br /> <br />Rueter-Hess Reservoir <br />Development Stages <br /> <br />- <br /> <br />Dam Height <br />Capacity <br />Reservoir Footprint <br />Dam Length <br /> <br />Phase I <br />105 feet <br />10,000 acre-feet <br />275 acres <br />2,000 feet <br /> <br />Phase Ii, <br />185 feet <br />55,000 acre-feet <br />975 acres <br />6,100 feet <br /> <br />5611i.rpt <br /> <br />-10- <br />
