> Statewide precipitation for the water year to date is 73 percent of average. Sierra-Cascades snowpack for the water year to date is 10 percent of average, down from 18 percent last week. Statewide reservoir storage is 71 percent of average for this time of year. And more stats like that. Where are the stats about California's reservoir levels? Isn't that the relevant metric? The state's very existence depends on water being in those reservoirs. Should one or more of them actually run dry, I don't think there is even a plan for what happens next. Along those lines, where are the mandatory cutbacks in water distribution to conserve what's left? |

Snowpack is not an irrelevant statistic. Gradual melt from snowpack is what flows into reservoirs. 10% of avg snowpack now means significantly less gradual resupply as we head into summer.
“ Snowpack accounts for the much of California’s water source and storage, because early spring snowpack “contains about 70 percent as much water, on average, as the long-term average combination of the major and ‘other’ reservoirs” (Dettinger and Anderson, 2015).”
