The story of water in the west is hundreds of years old now
To get a perspective I noticed in the states look up the damn building projects that occurred for instance
Lake Shasta
The grand Coulee Dam
Lake Berryessa
The Hoover dam
These were a man of engineering projects at the time and quite amazing when you study what they did back in the 30s to do what they did
They should blow up the hetch hetchy dam
Amazing they had the forethought to build those dams in the 30s considering there had never been droughts in the southwest since global warming hadn’t been invented yet
