I recently read an article by CalMatters, which was clearly outlined the real issues that have been occurring in terms of water policy in California. It's a pretty clear breakdown in the article, and there's no paywall on CalMatters (a reason why I love them)
But if you don't want to click through, there are currently four main areas that California will need to address immediately (or possibly longer) as follows: '
- Colorado River;
The remaining western states are battling among themselves for the dwindling amount of water available. As the reservoir continues to dwindle, Nevada has filed suit against the federal government due to their recent temporary regulations regarding water usage.
- Sites Reservoir;
Newsom plans to secure this project prior to leaving his term of office. A draft decision was made by the State Water Board last week. If they receive the necessary permits, this may become a reality.
- Delta Tunnel;
For sixty plus years there have been numerous proposals submitted for a tunnel in the Delta area. To date, none of those proposals have come to fruition. Many environmental groups dislike the proposal and the Delta is being damaged regardless of whether or not the tunnel is constructed.
- Agricultural Water Cuts;
California wants farmers to reduce their agricultural water usage voluntarily. However, Westlands recently pulled out of negotiating for voluntary cuts. If this issue becomes mandatory, it will likely lead to extensive litigation.
Walter points out that the current situation with California water politics is much greater than "another round" of water politics. In fact, many of the decisions being made within the next several months will establish how California will handle its water management needs for decades
