The charts I could find online are all several years old. I wouldn't doubt ag use is even more. The amount of newly irrigated land in the last 20 years in Southern Alberta is staggering.

The amount of water lost to evaporation from canals must be quite significant. It's costly but replacing canals with pipelines could potentially reduce the amount of water drawn from rivers. At some point does the value of water make it economical to start replacing our canals?
