Are Reservoirs are Now Full, Months Ahead of Time

The recent rain has done something amazing:  filled many of our reservoirs to full, months ahead of time    

Levels of fill that normally require snowpack melt during spring.

Consider the all-important Yakima Reservoirs (below), which are now at levels normally only reached in mid-June.  Amazing.

In Seattle, the reservoir levels exceeded normal maximum levels in June, and they released some water to ensure sufficient capacity to handle flooding:


What about Spada Lake, the massive storage reservoir for Everett?  It is now full! (blue line is this year, brown line is full)


The Northwest River Forecast Center's predictions for local streamflow are getting more favorable for regional rivers, as illustrated by the 120-day prediction of streamflow for mid-summer (below),   Most are around 100% of normal


To provide a specific example, there is the extended forecast for the Yakima River.  Black is the predicted for this year.  Much above normal (green line) into May and near normal during mid-summer.


Bottom line:   I am cautiously optimistic about our Washington State water resources this summer and that there will be no drought.
