capacity. which is 8.222 mafless than one year ago.

December releases from Hoover, Davis, and Parker Dams averaged I 1,890,8,850 and 5,240
cubic feet per second (cfs), respectively. Planned releases from those three dams for the month of
January 2003 are 10,900, 10,300, and 5AOO cfs, respectively. The January releases represent those
needed to meet downstream water requirements including those caused by reduced operation of
Senator Wash reservoir.

year 2002. as estimated by Board staff, totals 8.675 maf and is projected as follows: Arizona, 3.056
maf; California, 5.3 I I maf; and Nevada, 0.308 maf. Unmeasured return flow credits of 0.263 maf
would reduce the total amount of projected consumptive use to 8.412 maf. All three Lower Basin
states have increased their consumptive use of mainstream water due to a drought condition.
