Show Final Report Hydrologic Model Analysis of the Provo River Basin 1.0 SUMMARY OF STUDY PURPOSE, MODEL SCOPE, AND RELATIONSHIP TO OTHER STUDIES This report documents a Hydrologic Model Analysis of the Provo River Basin conducted by the Central Utah Water Conservancy District ( CUWCD). The study documented herein resulted in the development of a computer model called PROSEVI ( the Provo River Simulation Model) that simulates the Provo River system, including the Weber River, Utah Lake, and transbasin diversions into the Provo drainage. The purpose of this document is to provide an understanding of the following: 1.0 The objectives and purpose for this study and the capabilities of PROSIM 2.0 The public involvement program and the analyses performed in the development of PROSIM 3.0 Model results from the analysis of historical conditions 4.0 Model results from the analysis of proposed demand conditions 5.0 Future plans for the use of PROSIM Each of these topics is covered in the correspondingly numbered section of this report. Summaries of 1) transbasin diversion rights from the Weber River and 2) the " public involvement" in the preparation of this report are included in the appendices. 1.1 Authorization The Central Utah Project ( CUP) was originally authorized in 1956 as part of the Colorado River Project Storage Act. The entire project consists of five units in the Uinta Basin of the Colorado River and one unit that includes parts of the Colorado Basin and parts of the Great Basin. This last unit, the Bonneville Unit, includes the Provo River system. The Central Utah Project Completion Act ( CUPCA) is a part, of PL102- 575. CUPCA was signed into law by the President of the United States on October 30, 1992. CUPCA authorizes CUWCD to complete the remaining features of the Central Utah Project. The Completion Act is multi- faceted and includes requirements for CUWCD and/ or the Utah Reclamation Mitigation and Conservation Commission ( URMCC) to complete several separate features, including six studies of areas of the Provo River drainage and Utah Lake, collectively designated by CUWCD as Provo River/ Utah Lake Special Studies. The CUWCD provided funding for this Hydrologic Model Analysis project under authority of CUPCA, Section 202( a)( 5)( A)( i), as part of the Provo River/ Utah Lake January 1998 Page 1 |
