As we head into the second half of the winter season, reservoir storage across the western USA is in fairly good shape.
Since 2013, there have been several good snowpack years across the mountains of the west, which in turn has enhanced reservoir storage that was in poor shape after the 2011/2012 western drought years.
The graphic below shows water storage conditions in the west as of January 1st 2020.
Only two states have below average reservoir storage. New Mexico and Washington have less than 50% storage levels. Recent good snowpack years in Montana, Nevada, California, Wyoming and Colorado have helped reservoir levels grow and maintain high levels.
