California has been blessed with a wet winter this year. At the time of publishing, most of the state is at or well above the historical average precipitation to date for this time of year and Sierra Nevada snowpack is at more than 140% of historical average. That’s been good news for the California plants, animals, and humans that rely on water to survive and recreate. But lots of precipitation now doesn’t necessarily mean that California will have lots of water when it needs it. That’s because what matters is not only how much water we get, but when and how we get it.
