Show Final Report Hydrologic Model Analysis of the Provo River Basin Study of the Central Utah Project Special Studies Program. The authorizing legislation states, ... the District ( is) to conduct with Public Involvement a hydrologic study that includes a hydrologic model analysis of the Provo River with all tributaries, water imports and exports and diversions, an analysis of expected flows and storage under varying water conditions, and a comparison of steady state conditions with proposed demands being placed on the river and affected resources, including historic diversions, decrees, and water rights.... 1.2 Study Objectives and Purpose As decreed by the authorizing legislation, the objectives of this Hydrologic Model Analysis of the Provo River Basin are to develop a comprehensive understanding of the hydrology, water rights, and operation of the Provo River system, and to translate that understanding into an effective planning tool that can be used to perform studies of the operation of the system. Specific objectives were developed for the hydrologic analysis, the water rights analysis, and the computer model itself. The specific objectives of the hydrologic analyses include developing a consistent, complete database of the natural streamflow, historical diversions, and meteorology of the system. The water rights analysis objectives include identifying, describing, and assigning relative priorities for all water rights, applications, and institutional arrangements. The objectives for the PROSIM model itself include those listed below: • The inclusion of all critical information gained from the hydrologic and water rights analyses. • The ability to estimate how the waters of the Provo River are allocated to each major water right holder on the system over a lengthy study period, under a variety of operational conditions. • The ability to estimate instream flow conditions throughout the system. • The ability to estimate how much water the major reservoir projects may be able to store and release from storage. • The ability to examine the effects of changes in operational assumptions upon any of the items listed above.
