Values displayed in red represent averages that are at least 5 psu below the SUB. If either the daily or ten-day average is at least 5, 10, or 15 psu below the Salinity Upper Bounds (SUB) for ten consecutive days within the given month, then the monthly pass-thru target, which is based on the combined reservoir system volume, may be reduced by the following amounts:

Months Reduction for Average Salinity
5 psu below SUB 10 psu below SUB 15 psu below SUB
Jan, Feb, Mar, Apr, Jul, Aug, Nov, Dec 25% 50% 75%
May, Jun, Sep, Oct 0% 25% 75%
