Notes:
(1) = Monthly fraction of evaporation for elevations below 6500 ft from Guidelines
for Substitute Water Supply Plans.
(2) = Gross free water surface evaporation from NOAA Technical Report NWS 33
(3) =Columns(1)x(2)
(4) =Total free water surface area- 12.8 ac.Assumes ice cover for Dec-Feb
(5) = Columns(3)x(4) ��� 00(bfcS
(6) = Mean Rainfall (1948-2000)atl:e�t,from Table AI.6
(7) = Effective Rainfall= Column (6)*0.7
(8) =Column (7)*(1/12)'Column (4)
(9) = Column (5)-Column (8)
(10)= IDS AWAS Steady State Lagged Depletion Output from Table AI.5 and Normalized to equal the total in Column (9)
