Canal sized pipes?

And suddenly you can build something else on those pipelines?

I'm sure it could be done, but it would cost a fortune. My understanding is the canals were built to distribute water to farmers, and conservation/evaporation wasn't really much of a consideration because California had plenty of water back then.

BTW, I used to swim in those same canals around Modesto and Turlock as a kid. So gross.

According to AI, that pipe would only need to be 43 Feet in diameter, only 43 feet wide. Pretty sure they have that at Home Depot.
