'90%; 70%, 30%. and 10% chances of exceeding are the probabilities that the actual volume'w~ll exceed the volumes in the table.
average is computed for the 1971-2000 base period.
~ _ The values ~isted under the 10% and 90% Chance of Exceeding are actually 5% and 95% exceedance levels.
The value is natural volume - actual volume may be affected by upstream water management.
