I haven't read all of the posts here so if I'm repeating somebody else's posts, I apologize.
I live in California and I have riparian rights and a well. In my situation the state is asking my neighbors and myself to cut back on our water usage. For the most part we all have. This is called management. The state also requires us to report and meter usage above 10 acre/feet per parcel. This requirement has caused some issues in that a parcel may be 1 acre or 600 acres. I will do my best to be diplomatic and say they're still working the kinks out. I suspect that if the state starts charging for water usage on these rights they'll see a whole large parcels divided up as a work around.
I hear people all of time threatening to move out of state. My response is usually "Give me a call when you get back". I, myself, have moved out twice, for work. I lived and worked out of state and overseas. I love California. I find it curious that folks from out of state are complaining about California. In my entire time here I've never heard any one complain about another state they hadn't been to.
California gets demonized a lot. It's the mass social equivalent of an ad hominem attack. I don't know the Latin for that, but California gets to solve it's own problems and reap its own profits. Nobody else gets a vote. I have family living in California, Texas, and Florida. Not my kettle of fish, but it's their business, not mine.
In 1961, my dad bought a dry land farm. A couple years later some neighbors got together and developed a small intermittent stream that ran on one side of the property. If they pumped water out of the Willamette River, the water would run parallel to the river for about 8 miles before returning to the river. It turned the stream into an irrigation canal. Getting water to the property doubled its value overnight. I was a teenager, and he hauled me along to the organizational meetings.
Filing for water rights was a complex process. According to the State, there was still (1963) free water in the Willamette. However, the Corps of Engineers has a network of flood control dams and according to them the water was theirs. We filed water rights with both the State, which was free, and the Corps, which was not. That put us down the list for senior State water rights, and almost first in line for Corps water rights. The last I heard, they had signed up about 55,000 acres. Maintaining water rights on an individual parcel is on a "use it or lose it" basis. You have to irrigate at least once every 3 years, or your water rights expire and you slide to the bottom of the list.
The irrigation district water rights are superior to several municipal water systems. In 1963, towns were still getting away with a well or two and a few springs. In 1977 it didn't rain, and the wells and springs dried up. Cities decided to build water treatment plants and pump river water. Most of them hadn't bothered to file water rights on the river until then.
In miniature, it's what happened in California. The water projects were irrigation districts built and maintained by farmers. Irrigation water is allocated by seniority, and there is already a lot of land not being irrigated because of the drought. The cities are screaming, because they are used to unlimited cheap water. Some cities don't even have water meters for individual customers. The Corps controls a lot of the water, and they just reduce deliveries because they don't have it. Some customers have switched to pumping wells. That's a limited resource and won't last long. The State is curtailing use by industrial/commercial users because they have to. It has nothing to do with any ideology, it's only reality. If there is no water, there is no water.
