By the year 2000, Lower Basin users of Colorado River water can suffer detriments of $80,000,000, if control measures are not instituted to prevent increased concentration of dissolved solids (salinity). Projected increases in water consumption in the Colorado River Basin will cause an increase in salinity of 330 mg/L by the year 2000 at Imperial Dam. The effects of increased salinity on agricultural and domestic water users and measures to cope therewith are described. Data are provided on current estimates of Colorado River depletions up to the year 2000 and the effect they will have on salinity. Data from studies of penalty costs due to salinity are used to determine the full economic impact on users of Colorado River water in Arizona, California, and Nevada for the years 1980, 1990, and 2000.
