How so? Even if the models are correct, Southern CA is expected to receive a bit less rainfall, Northern CA a bit more. Even assuming there's a net deficit, the simple expedient of expanding irrigation, possibly supplanted with a few large nuclear desalinator plants, would obviate the problem entirely. We're talking about 22nd Century level technology here, remember.

Let's not forget that increasing CO2 also reduces water needs for plants, they process water more efficiently. And I won't even bring up the fact that California currently grows a large number of crops very high in water usage-- they even grow two million tons a year of rice for god's sake. Even assuming no other mitigation measures were taken,the simple expedient of choosing a more appropriate crop, would again solve the problem (if it even exists) handily.
