    If the price is right they'll propose building a pipeline from either the Great Lakes or the Yukon and replacing Colorado water with that.

      ...and have previously floated the idea of pipelining water from the Pacific Northwest down to California to supplement shortfalls from the Colorado River.  However, so far political forces in the Pacific Northwest have successfully blocked that idea as a complete nonstarter, and it's been awhile since California has tried to actively revive the idea.  But not because they wouldn't if they thought they had any chance of forcing it through.

        with Northern California about water.  We have water wars.  The developers in the South of the State complain about the lack of enough water transported from north to south, the farmers in the Central California area get less and less for crops, and most of the water that either receives comes from the Northern Sierra Nevadas.

        There is some local water for SoCal, but not enough - because those developers continue to build homes and businesses where there isn't any water - in the desert.  The same happens in Arizona, which gets its water from the Colorado River - and they build, again, where there is no water.  

        It's nearly impossible to 'waste' water in Northern California (but some does get wasted) - because any water used goes into (1) the ground water tables that are fed by the same rivers (and local rain, which hasn't yet appeared this water year), (2) sewage treatment plants that treat the water and return it to the river, or (3) into human bodies - which I don't consider a waste at all.
        The water is returned to the sea-ward path but gets to either the San Francisco Bay through the Delta (which pumps millions of gallons of water - and fish parts right out of the Delta), or to Central and Southern California through a huge system of canals - before it reaches the sea.

        On the other hand, pumping enormous amounts of water from Northern California to Southern California, which feeds sprinklers, fountains, water parks, landscaping, etc.  - IS wasted because from there it just goes to the Ocean if it goes into the already-low water tables.  There are of course good reasons for sending water from north to south, but too many bad reasons.

        The USGS has a site about 'subsidence', with a few interesting photos that clearly show that the elevation level in certain parts of California has dropped nearly 50 feet - because they take so much water from the underground tables - the land sinks and compacts above it.  The compacted earth, as a result, cannot 're-fill' the tables.  Sort of like a sponge with a brick on top of it can't absorb nearly the same amount of water.

        Here's a link for that.
