. 90t, 70'. 30t, and lOt chances of exceeding are the probabilities that the actual volume wl11 exceed the volumes in the table.

The average is computed for the 1971-2000 base period.

(1) The values listed under the lOt and 90\ Chunce of Exceeding are actually 5' and 95t exceedance levels.
(21 The value is natural volume actual volume may be affected by upstream water management,
