Locations with an `N` suffix indicate natural flows excluding
stream augmentations.

KAF: Thousands of Acre-feet

%AVG: Current 50%/AVG

AVG: Average(50%) seasonal runoff voulme as simulated by the river
forecast model considering acontinuous simulation of the basin
response to historic climate data (observed precipitation and
temperatures) over the period of 1991-2020.

The 50%, 10% and 90% columns indicate the probability that the
actual volume will exceed the forecast for the valid time period.

Beginning April 1, May and June official forecasts include observed
runoff volume up to official forecast date.
