I think this makes sense!
All things being equal it would, but my understanding is that most years the Colorado doesn't make it to the Pacific Ocean because so much water is removed from the river. That would mean that during dry years the river doesn't reach the Pacific and during wet years they want to remove more water thus making the Colorado flow into the Pacific even less of the time. From what I know about marine estuaries, they are considered extremely productive habitat. This has to have some fairly steep environmental impacts if I understand it correctly.
