Statewide reservoir storage is below average


Lake Natoma
California’s reservoirs are low for this time of year. The statewide reservoir storage level is 79% of average and is forecast to continue falling. The reservoirs are low because the snowpack last season was light and rainfall has been nearly nonexistent in most areas this fall.
Statewide totals on September 30 were: precipitation was 80% of average, runoff was 60% of average, and reservoir storage was 80% of average. Those numbers continue to fall due to the lack of rain.
The California Department of Water Resources is reporting the driest period in 90 years for January through May in 2013. The next statewide hydrological condition report will be issued in November.
The highest precipitation months are December through March, so it is possible to get back to average or higher by spring.
