..... Isn't that the same Northern and Central California that is on fire and in extreme drought right now? Those tunnels only solve an evaporation issue but not the water supply issue. There needs to be local and county solutions to the water supply problem such as collection and storage of water when it arrives and not just bringing it from other areas.
And after El Nino (no, not El Chappo) cures the drought, they can use the tunnels for the bull*** train.
It's the same delta that isn't getting water that has been diverted for "ecological purposes" and a smelt.
This scheme sounds like it anticpates a land grab and tax dollar boondoggle, having very little to do with redirecting water that isn't there to be redirected.
(The gardener (green card) just came by, looked at the front yard, shook his head, stirred the soil around the dying roses, and left; no mid-winter tomatoes happening this year.)
