Notes:
(A)Total average farm headgate deliveries(FHG)to the recharge ponds based on HCU for portion of Taylor and Gill Ditch water
sent to the recharge ponds.
(B)Evaporation estimated based on total recharge pond surface area when deliveries are being made.Surface area of recharge ponds
are expected to be 1.5 acres during the 2016 irrigation season.
(C)Equals(A)-(B)
(D)Lagging calculations were based on the following parameters:
Distance from stream=2,300 ft,Transmissivity=160,000 gpd/fl,Specific Yield=0.2,No-flow Boundary=6,500 ft
(E)Return flow factors are based on HCU analysis conducted by Appelgate Group,Inc for the 5.75 shares of Taylor and Gill Ditch W;
(F)January-March=(2015 Deliveries*(E)),April-September=(B)*(E),October-December=(2016 Deliveries*(E)).
(G)Equals(D)-(F)
