~ <::> c..o 0') Figures 2-4, 2-5 and 2-6 summarize data from past Reclamation progress reports, 12 comparing the adjusted salinity (to reflect long- term mean water supply) to the numeric criteria at the three water quality stations through time. Adjusted salinity values were not reported during the 1980 through 1990 period. The figures show that at times in the past adjusted salinity values were above the numeric criteria.

The central feature of the CRSS is a computer program which simulates the flow of water and salt through the system and the operation of the mlijor reservoirs including hydroelectric power plants. 120tIBlity of Water, Colorado River Basin, Profr....
