Wait, fucking what?
I mean, I know this is the state that uses most of its potable water on cash crops while large portions of the population/areas suffer water shortages, but... fucking what?
It's not
quite as one-sided as Agent is suggesting here. The Sacramento-San Joaquin Delta is a huge estuary that has around 80 species of endangered fish in it, the one Agent's talking about is probably the plankton-eating silver minnow but there's lots more that are endangered and even more that are threatened.
California needs to allow the San Joaquin river to actually reach the pacific ocean for the delta to keep existing. The San Joaquin river is already one of the most heavily dammed and diverted in the nation, and tying up more water from it would basically mean no water reaches the ocean and the entire delta dries up and a massive chunk of the entire coast ecosystem dies. This is the single biggest delta between Alaska and Argentina and an ungodly number of species, some endangered and some not, need it as their hunter and feeding grounds. Meanwhile, a metric buttload of farmers see millions of gallons of water flowing into the ocean, gallons of water they have to pay for.
Honestly, I'm more on the side of the minnows here as this is an estuary worth preserving, California isn't actually
dumping any water, they're simply mandating that the minimum percentage of the river necessary to keep the delta alive be allowed to reach the shore.
