Notes:
[ t ] Monthly percentages determined in SB89 -120 for elevations below 6,500 feet.
[2]Based upon NOAA Technical Report NWS 33, Evaporation Atlas for the Contiguous 48 United States.
[3] Total exposed surface area based on review of aerial photography.
[4] Gross evaporation = [2] x [3].
[5] Based upon the Western Regional Climate Center Station for Pueblo, CO (056740) for the time period 1954 -2005.
[6] Effective precipitation = [5] x 0 7
[7] Net evaporation rate = [2] - [6].
[8] Net evaporation depletions = [7] x [3].
[9] Reflects real time tagged depletions due to evaporation based on Glover analysis using a stream depletion factor of 7 3 days.
