No, I got my geography screwed up. So I’ll just describe it from the map. There’s a line of hills/mountains east of LA and SD that scrape water out of the sky for the coast. On the East side it’s much drier but they’ve got farms all through there and a couple towns.
I really don’t know where you’re getting your info. I grew up in CA and there’s no way SoCal gets more water of any kind unless it’s piped in. This precip map also proves that. The Sierras and Northern California get way more rain/snow than the San Gabriel or Bernardino mountains “scrape” out of the sky. The Sierras are a huge range compared to them, and when they do get snow, that water feeds into the lakes and rivers in the Valley. The precipitation map clearly shows SoCal can’t match any precipitation further up the state past Tehachapi.
