* 90'ls, 70'ls, 30'ls. and 10'ls chances of exceeding are the probabilities that the actual volume will exceed the volumes in the table.

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

(1) _ The values listed under the 10'ls and 90'ls Chance of Exceeding are actually 5'ls and 95'ls exceedance levels.
(2) _ The value is natural volume - actual volume may be affected by upstream water management.
