"While the state’s drought-induced sinking is well known, new details highlight just how severe it has become and how little the government has done to monitor it.
Last summer, scientists recorded the worst sinking in at least 50 years. This summer, all-time records are expected across the state as thousands of miles of land in the Central Valley and elsewhere sink.

No agency is tracking the sinking statewide, little public money has been put toward studying it and California allows agriculture businesses to keep crucial parts of their operations secret."
