Did you know there are 5 desal plants currently operating in California, with more in the permitting pipeline? 10,000x more capacity is not feasible and more importantly not going to solve this problem. Catalina Island now uses desalination which is the clearest and most obvious win for desalination.
The unsolved problems: energy, money, and brine discharge. Desalination is energy intensive. And with the highest energy costs in the nation, SoCal is in a really tough spot to use large amounts of energy on water. The subsidized water from the Colorado river is too cheap not to use.
Reservoirs: similar problem of money. The state has already dammed up all the cheapest and most obvious terrain in California. It gets more expensive to dam up new areas. Did you know there is another large reservoir in NorCal being planned that's almost a decade into funding/planning (Sites)? It's not directly on a river so will require active pumping. 2 more (Pacheco & Los Vaqueros) are being expanded in the near future from the same pile of money paying for the new reservoir. [1]
What California needs is rethinking existing potable water use and combine with smart rain capture. San Diego Airport in recent years has installed large capture cisterns for a parking lot that will offset its largest water use - HVAC for the airport. They've even piloted the capture of condensate from the land-based AC that is brought out to planes on the ground during turnaround. [2]
