Bay Area Air Quality from Napa and Santa Rosa Fires


The fires in Napa and Santa Rosa California have been burning for about a week and a half so far and these fires have resulted in numerous deaths (with many more missing), significant property damage (over 4000 buildings), and forced the evacuation of tens of thousands from their homes.  Luckily, these fires are mostly contained at this point with incredible work from firefighters and as well as from the weather (link to fire status on the CalFire’s websites on the Tubbs, Atlas, Nuns fires).

How Fast Are California Reservoirs Filling Up?


In my previous post, about California water levels, I presented a “bar graph” showing the amount of water currently in California’s reservoirs.  However, I thought it’d be interesting to see how this has changed over the course of the last few months, since the state has gotten alot of rain and snow recently.  I decided to try and “animate” the graph for the current water year (going back to October 1, 2015) showing how the recent El Nino rain has been filling up the reservoirs in California.  Click the “animate” button below the figure and you can use the slider to change the speed of animation as it cycles through the days.   (more…)

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.
