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% |
Below is a graphical representation of the averages listed above.
