Show Final Report Hydrologic Model Analysis of the Provo River Basin The Provo River Decree ( also known as the Morse Decree ( 1921)) was reviewed and digitized to allow computer searches by name, flow, or location. A number of major rights did not include diversion points or location of use. By comparing the State database, the Decree, and the lists obtained from the Deputy River Commissioner, all significant rights were identified by location and flow. Meetings were held with representatives of the following major water users: • Orem City • Provo City • Provo Reservoir Water Users Company • Salt Lake County Water Conservancy District • Metropolitan Water District of Salt Lake City • Provo River Water Users Association • Central Utah Water Conservancy District • United States Bureau of Reclamation These users provided information about water ownership, as well as projections of future water usage. 2.4.2 Analysis of Water Rights The accumulated water rights information was analyzed to determine which significant rights would be modeled individually by PROSIM and to identify other valid rights that could be lumped together in the model. Significant rights included all those belonging to canal companies and public entities. An attempt was made to account for or lump together all rights specifically identified in the Provo River Decree, regardless of the size of flow. The collection phase identified 875 water rights in the system. These were aggregated into 119 modeled rights, by combining smaller rights diverting at a single location or canal. This combination of water rights mirrors the way water is actually allocated by the Provo River Commissioner. To facilitate the analysis of water rights, and the review of the water rights information by water users, water rights abstracts were developed for the following six major water users on the Provo River: USBR, Provo City, Provo Reservoir Water Users Company, Wasatch Division canal companies, Provo Division, and Orem City. Abstracts prepared for these users were important in identifying the completeness of the data and comparing water right numbers with Provo River Decree classes and paragraphs. USBR's abstract was important because USBR holds the water rights for the Weber River Project, the Provo River Project, and the Central Utah Project. January 1998 Page 15 |
