Notes:

(1) USGS Water Supply Papers; inputs to model.
(2) Above Powell from Iorns et a1., (1965), p. 34. Side flows
above Mead from Feeny, (1975)
(3) Powell evaporation from tables using recorded storage (no USGS
estimates published); Mead evaporation from USGS Water Supply
Papers.
(4) Modeled evaporation from evaporation versus storage tables,
change in storage taken as llS = I - E - D.
