IIRC, the electricity on both sides of the state lines at Hoover are split to the respective state and California gets some from one or the other or both. I also seem to remember something about a really long canal from Meade or thereabouts going onto California too.
Hmmm. Don’t recall Cali doing an eminent domain thing with Lake Mead. LOL! Yeah, no doubt the get some of the voltage from there though. Luck thing they installed a bunch of super efficient solar panels at that big chunk of desert tortoise habitat/sanctuary south of Vegas. Just how many tortises did the relocate for that site?
