Show Final Report Hydrologic Model Analysis of the Provo River Basin Significant System Storage assumptions used in modeling the Proposed Demands Scenario are listed in Table 4- 2. Table 4- 2 Proposed Demands Scenario System Storage Assumptions Utah Lake Distribution Plan is assumed to be in effect. Olmsted power right allows CUP to store Provo River flows less than 429 cfs as CUP system storage. PRP stores 5,000 acre- feet per year of Provo River water as PRP system storage. ( PRP is entitled to an average of 5000 AF/ yr over a 10- year period with an annual maximum of 10,000 AF.) Storage of Provo River water in Jordanelle and Deer Creek is limited by calls from Utah Lake when Utah Lake primary storage falls below 125,000 acre- feet. System Storage conversion line is reduced by CUWCD's Utah Lake water right purchases, which are left in Utah lake. System Storage conversion is permitted every month. Strawberry/ Jordanelle exchange is permitted in June - October. 4.1.5 River, Reservoir, and Project Operations A large number of Provo River system operations are modeled in the PROSIM simulation of the Proposed Demands Scenario. These include such operations as direct flow water rights diversions; individual owner and user reservoir accounting, calling, and exchange procedures; and CUP and PRP operating rules. The details of these and other operations, and how they are simplified and simulated in PROSIM, are documented in the draft Technical Memorandum # 3- Provo River Water Rights Analysis and draft Technical Memorandum # 6- Weber River Water Rights Analysis, CUWCD, 1993b, and 1993e. The individual assumptions will not be repeated here, except in the abbreviated list presented in Table 4- 3. January 1998 Page 28 |
