Water Supply Outlook Report
The Water Supply Outlook Report (WSOR) contains water supply forecasts, which are statistical predictions of streamflow volume that will flow past a point on a stream during a specified period of time, typically in spring and summer. These forecasts are given not as a single number, but as a range of numbers to reflect forecast probability and uncertainty. Learn more about these forecasts and how to interpret them.
Reports are available for the first of each month from January to June.
This directory provides access to all historical reports from 1990 to present. To view a historical report, simply select the "Water Supply Outlook Reports" drop-down menu, then select the water year of interest.
