Water Supply Verification - Major Basin

The following are water supply verification graphics that compare the forecasted April - September (seasonal) forecasted volumes to the observed volumes.  Seasonal runoff volumes are forecast each January, February, March, April, May and June. The verification graphics are displayed as a percentage and are calculated as the Forecasted Volume / Observed Volume. For example 125% would mean that the forecasted volume for that forecast would be 25% more than what occurred, and similarly 75% would  mean that the forecasted volume for that forecast would be 25% less than what occurred.
