How Much Water is in California Reservoirs? – Current and Historical Visualization

California has been in an ongoing drought for a couple of years now.  This year’s El Nino weather pattern has brought a significant amount of rain to the state so far.  As of early March, we are just a bit above average in precipitation in the Northern, Central and Southern California mountain regions. As a California resident with an interest in environmental issues, I’ve been very curious to understand how the rain storms we are experiencing are lessening the impact of the drought, and whether one wet season can really “get the state out of a drought”.  One way to assess this is to look at the status of California reservoirs.
