| Relation | Central Utah Project; Western Waters Digital Library; refer to chapter 2 for information on evaporation and precipitation rates used in the simulations overall simulation accuracy based as much on judgment after working for thousands of hours with the hydrology and water quality of the utah lake system as on any particular numerical or statistical premise estimates of error of the utah lake simulations are 57a 5 for annual values for evaporation 5 for combined annual surface inflow 2220 20 for combined annual groundwater inflow and j 5 for simulated main lake conservative ion concentrations errors in individual components of surface and groundwater volumes and quality might occasionally be quite large but such errors have only a small effect on the overall balances since they tend to cancel each other over time measured lake quality data showed good agreement with the historical simulated quality as was shown in figure 2a aa 3 simulation RESULTS results of simulations are summarized in table 3a aa 1 evaporation rates As discussed in chapter 2 evaporation studies indicate that an annual evaporation pan coefficient value of 0.92 092 should be used for the lehi evaporation pan to estimate annual utah lake evaporation rather than the value of 0.80 080 often used in the past use of the larger coefficient value increases the evaporation loss by about 39000 afyr adyr for the entire lake in provo bay and goshen bay very shallow waters hence warmer water temperatures and more abundant emergent vegetation are perceived as giving a few percent higher evaporation in those areas than in the main lake to this time however it has not been possible to quantify actual differences in magnitude 3 6 |
