Water management in Florida regularly dumps a lot of fresh water into the Intercoastals, causing bacteria blooms and other damage to otherwise pristine ecosystems. If the West needs water, they should build a siphon-driven pipeline from Florida over the Rockies and clear out to the coast of California, serving everyone along the way. I think there is plenty of fresh water in Florida to go around, at least until Florida's population grows so large it depletes its aquifers, which I suppose is already happening, but they're still just dumping fresh water into the ocean.
