The average is computed for the 1971-2000 base pariod. * 90%, 70\, 30\, and 10\ chances of exceeding are the probabilities that the actual volume will exceed the volumes in the table. (1) _ The values listed under the 10\ and 90\ Chance of Exceeding are actually 5% and 95\ exceedance levels. (2) _ The value is natural volume - actual volume may be affec~ed by upstream water management.
