* 30 Year Averages for 1971-2000 are incomplete.  Those forecast
points with an asterisk have incomplete averages, so 1961-1990 averages
are listed.  The new averages will be incorporated into this product
when the complete data sets become available. 

** Pit River 30-year average is full natural flow.			

MP    Most probable volume in 1000 acre-feet.
MP%   Most probable volume in percent of the 71-00 average.
RMAX  Volume that has a 10 percent chance of being exceeded.
RMIN  Volume that has a 90 percent chance of being exceeded.
AVG   Average volume for the 71-00 period.

All forecast volumes reflect natural flow.  Actual observed flow may
be affected by upstream water management.
