| Relation | Central Utah Project; Western Waters Digital Library; the USBR USER has used a project water savings of 105000 afyr adyr in their planning this value seems to be rather optimistic unless as explained above the goshen bay fresh water inflow is much less than it appears to be and unless much of this water could be captured by surface runoff drainage ditches well drilling and pumping and unless the briny water behind the dike could be partially segregated and the better waters used for wildlife habitat areas or other beneficial project uses lake levels variations in lake levels for the six future simulations were much the same as for the historical period except that the maximum lake level allowed was 4489.34 448934 feet compromise level A summary of historical and simulation lake levels is given in table 3a aa 2 for run 2 jordan river outflows were left the same as for the historical outflows and any water volume above compromise elevation was simply exported for the other runs a minimum flow of 220000 afyr adyr was maintained in the jordan river except during drought years 1933 through 1936 1940 1941 and 1963 the minimum flows during these drought years were as established in earlier USBR USER water balance and operations studies lake drawdown earlier operations studies by the USBR used either 9.3 93 93 feet or 12.0 120 feet below compromise as the maximum allowed drawdown with 9.3 93 93 feet as the more probable objective the maximum drawdown in each of the six future simulations in WHAB studies are given in table 3a aa 2 and range from 9.98 998 to 11.68 1168 feet these drawdowns draw downs which are about 0.7 07 07 to 2.4 24 24 feet greater than the 9.3 93 93 foot objective are not felt to be of serious concern since they occur for only a few months during the entire 50 year simulation and could be alleviated by release of a few tens of thousands of acre feet from upstream reservoirs if needed these additional flows were not added during WHAB WRAB simulations due to the desire to use essentially the same provo river and spanish fork river flows as established by earlier USBR studies larger evaporation rates in the WHAB simulations were the main cause of the greater drawdown A significant 310 3 10 |
