All of California is in "severe drought" (shown in orange), and 82 percent is rated “extreme drought” (in red). The agency’s highest drought rating -- “exceptional drought” (crimson) -- now covers 58 percent of the state, up from 36 percent a week ago. Exceptional drought is marked by crop and pasture loss and water shortages that fall within the top two percentiles of the drought indicators.
The water reserves in California’s topsoil and subsoil are nearly depleted, and 70 percent of the state’s pastures are now rated “very poor to poor,” according to the USDA.
Reservoir levels are dropping, and groundwater is being drained from the state as farms and cities pull from difficult-to-replenish underground caches. The state’s 154 reservoirs are at 60 percent of the historical average, or 17.3 million acre feet lower than they should be. That’s more than a year’s supply of water gone missing.
It’s not the worst drought California has ever seen -- in 1977, the state’s water storage was at 41 percent of the historical average -- but conditions are still getting worse.
