Notes:
(A) Total average farm headgate deliveries 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 diversions are being made. Surface area of recharge ponds
are expected to be 3 acres during the 2015 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/ft, Specific Yield = 0.2, No -flow Boundary = 6,500 ft
(E) Return flow factors are based on HCU analysis for the 5.75 shares of Taylor and Gill Ditch Water.
(F) January -March = (2012 Deliveries * (E) ), April -September = (B)*(E), October -December = (2013 Deliveries * (E)).
(G) Equals (D) - (F)
