With a little time out to deal with the Japs, the Jefferson State movement has been simmering since 1940...to no avail. But the big difference this time is ...this is a boundary change, as opposed to the the Jefferson movement which is forming a new state. As far as the California counties go, I was made aware at a meeting recently of a situation that could prevent the California mountain counties getting away from Sacramento, regardless of the method. The simple fact is, the mountain counties generate the WATER to sustain 1/3 of US vegetable production and 2/3 of the US fruit and nut production, not to mention clean sustainable hydropower, not to mention lumber production. The big money ag simply will not let the golden goose out of the pen.
This is true in large part. Can anyone imagine the Ag community, and various municipalities, giving up control of the water in the Sacramento system, a fairly large portion of which now comes from the Klamath/Trinity system by way of pumping over the mountains? Where this new entity could perhaps charge what the water's really worth, or worse, close the tap? Never gonna happen.
And according to some sources, the State of Jefferson movement started back in the 1850's, in various iterations.
