I always wondered if it would be possible to run flexible pipelines floating close to the bottom of the ocean which could transport fresh water between far flung areas. Imagine if you could siphon some of the freshwater outflow of, say, the Columbia River and send it down to SoCal or AZ farmland.

It'd be easier to build and maintain a canal. If you're worried about evaporation, then just build a canal to the ocean and desalinate the water. It'd probably consume much less energy than a mega pipeline.
