<br />, -. <br /> <br />,- <br /> <br />TASK NO.: 6 <br />RFP CROSS-REFERENCE: <br />Step 2, Item (2) <br /> <br />STAFF MEMBERS RESPONSIBLE: <br />Hydrologist <br />System Operation Studies Specialist <br />Dam Evaluation Specialist <br /> <br />TASK TInE: <br /> <br />Estimate of Excess Water Supplies in the Overland Ditch and Reservoir <br />System Available for Transbasin Diversion. <br /> <br />RATIONALE: <br /> <br />To estimate the gross inflows available for diversion by the Overland Ditch <br />and Reservoir system and the resulting water supplies excess to the demands <br />of the system and potentially available for trans basin diversion to the Surface <br />Creek basin a computer simulation of the hydrologic operation of the system <br />must be conducted. <br /> <br />. <br /> <br />METHODOLOGY: <br /> <br />1. Evaluate the results of Task No. 5 to determine whether excess water <br />supplies are available under existing operation of the Overland Ditch and <br />Reservoir system, and whether additional water could be made available <br />through improved management, if opportunities for such were identified, for <br />diversion to the Surface Creek basin. <br /> <br />2. Review the physical storage restrictions presently imposed on Overland Dam <br />by the State Engineer and the status of proposed reconstruction or replace- <br />ment of the dam on the basis of information obtained in Sub-Task No. 5.6. <br /> <br />3. Determine the most probable future plan for Overland Dam, viz. its operating <br />capacity and location. <br /> <br />1;. Prepare a computer simulation model of the Overland Ditch and Reservoir <br />System tributary basins and operate for the 27-year study period on a <br />monthly basis under the proposed future operating conditions to determine <br />the gross water supplies available to the Overland Ditch and Reservoir <br />system. <br /> <br />5. Combine and evaluate the results of Steps 1 and I; above with regard to <br />supplies required for utilization in the Overland Ditch system under the <br />selected level of improved management identified in Task No.5 to estimate <br />the gross water supplies available for diversion to the Surface Creek basin. <br /> <br />1I-13 <br /> <br />Revised 9/23/1985 <br />
