o en to I=> o ~~ Water and Salt Budgets Figures 7 and 8 are computer presentations of the water and salt budgets. The same method will be used for presentation of post construction measure- ments and calculations. The budgets will also be used to predict project benefits (Stage One Development, Grand Valley Unit, D,.finite Plan Report March 1980). Measured post construction flows and salt loads will be compared to the predicted values to evaluate project benefits. Statistical and graphical methods will be used to evaluate the presence and effects of typical weather Dr water deliveries. ponding tests, measurement of lateral diversions, revised evapotranspiration potential (ETP), and other pertinent information will be utilized to gather post construction data. The column explanations for the water budget are as follows: Inflow to the study area Column 1 Government Highline Canal.--The flows "ere calculated from the gaging station operated by the Geological Survey on the the Canal at 16 Road. CD lumn 2 Grand Valley Kiefer Extension. --The flows were calculated from the gaging station operated by thE: Geological Survey on the canal. Column 3 Inflow above Highline.--The flows above the Highline Canal were estimated at 10 percent of the precipitation falling on the drainage above the canal. Column 4 Precipitation.--Records for the study area were extrapolated from National Weather Service data collected at the Grand Junction Airport. Outflow from the study area Column 5 Government Highline.--The flows were calculated from the gaging stations operated by the Geological Survey and adjusted by Highline Lake operation study. Column 6 Grand Valley Kiefer Extension.--The flows were calculated from the gaging stations operated by the Geological Survey. 29
