Tldr: "the region lost 27.8 million acre-feet of groundwater since 2003, roughly the same volume as the total capacity of Lake Mead — the nation’s largest reservoir — and that the decline accelerated rapidly over the past decade. These groundwater losses accounted for more than twice the amount taken out of reservoirs in the region during that time."

The somewhat brighter bullet points: Northern California reservoirs are doing prety well, and the Bureau of Reclamatn can again kick the can by draining Flaming Gorge but i think this only works every few years:
