I have an idea. IID and other ag districts control 3.85 million AF of annual water allocation from the Colorado River. If they sold the rights to that water at, say, $5,000/AF they wold only need to sell 1.8 million AF to get the $9 billion of money they claim* to need. They have benefited from the water (and the sea/toilet) for the past 100 years -- they should pay the cost of cleaning it up.
Bottom Line: The Pols in Sacramento did the right thing -- no pork spending to clean up a local mess.
*If they were paying with their own money, I bet the cost would fall to about $2 billion. Right now, they want to use OPM, so they are gold-plating the project.
