More accurately:
Federal Court-ordered drainage of man-made lakes ...
Much as I generally respect VDH, he has his California geography wrong in this:
For 50 years, the state transferred surface water from northern California to the Central Valley through the California State Water Project and the federal Central Valley Project. ...
If you ignore the southern part of California that is south of the Tehachapi Mountains, half of the Central Valley is in Northern California. IOW, no "transfer" was necessary for that part of the Central Valley was necessary, because the Sacramento River and its tributaries flow naturally through the northern half of the Central Valley.
However, if one considers the full north-south length of California, most of the Central Valley is in the northern half of California. Further, that additional part of the Central Valley is watered by the San Joaquin River and its tributaries that flow naturally through that part of the Central Valley. So, again, water does not need to be "transferred" to that part of the Central Valley from Northern California because it is in Northern California.
How VDH has lived so long in California without learning the basic California geography that is taught in the 4th Grade in public schools (a legally required subject for both public and private schools), I do not understand.
2015 and 2016 were drought years. But then came winter 2016-2017, when the rain was so plentiful that moronic maintenance almost led to the Oroville dam collapsing (e.g.

While Hetch Hetchy does provide water to SF and some of the SF Peninsula, a glance at the East Bay and South Bay will show there are reservoirs on quite a few creeks that store considerable water (e.g. Anderson Reservoir on Coyote Creek in Santa Clara County has a capacity of ~91,000 acre-feet), and where suitable, these creeks also have parallel percolation ponds that are used to store far more water in the aquifers (e.g. Los Gatos Creek, which has two reservoirs and a series of percolation ponds, as does Coyote Creek). Putting it kindly, VDH very over-simplified the water situation in the SF Bay Area. Also, had VDH actually toured South and East Bay neighborhoods he would have found that many homes had (and still have, for that matter) brown lawns, including Appletino (aka Cupertino).
