Great job by Jay Lund in unpacking the issue of California water storage – how much it has, how it’s used and what role it might play going forward:

Climate warming is reducing the ability of California’s snowpack to store water seasonally. Fortunately, downstream reservoirs on many streams are already large compared to seasonal changes in streamflows and flood peaks. Model results show that with the right management, climate warming might be inconvenient, not catastrophic, for most water uses.

It’s not all about climate change, it’s really about how the system fits together. I recommend the whole thing.
