If you’re interested in tracking reservoir storage, river flows and the snow-water content in the Sierra, the state has a web site for you — California Data Exchange Center, known as CDEC.
I am particularly interested in the amount of water frozen in the snow. Water content gives you an idea of how much water can be expected next spring and summer when the snowpack melts.
About this time of year, I like to compare the snowpack at this point to the snowpack last year. You can do that at this page.
As of Nov. 21, the Sierra is about the same as it was last year. It is less than average, but most of the season is still ahead.
River flows become more important later in the wet season, but any time is a good time to look up reservoir levels. Reservoirs are the bank account of water from previous seasons. They’re still looking pretty good, even though last year was a little dry.
Follow CDEC, and you’ll have an idea of what farmers, hydroelectric projects and many industries are watching this winter in California.
