Notes:
The numbers in this table represent the average monthly analyses over the 55-year study period presented in the Appendices; simple
subtraction of these numbers will not portray the correct values
A Study Period from 1950-2004; data taken from cdss website (http://cdss.state.co.us)
B Pro-Rata Farm Headgate Delivery is: Diversions less 15% ditch loss
C Irrigation assumed to be 60% efficient
D Calculated for 1/2 alfalfa and 1/2 corn grain, using Greeley UNC weather station (1950-2004) using State CU calibrated coefficients
E Calculated as part of the water budget analysis
F FHD (Col B) - Actual CU (Col E)
G Surface Returns were assumed to be 50%
H Subsurface Returns were assumed to be 50%
I Lagged flows were determined with AWAS using: 4,210 ft from river, 11,440 ft (width of alluvium), Trans= 117,000 gpd/ft , S= 0.20)
1 Net Accretions (shown as positive) and depletions (shown as negative) to the River
