I agree with you regarding the ratios you mention. Importantly, the Colorado River Compact was established during an atypically wet cycle, and even with ag reductions, I’d argue no additional pressure should be placed on the watershed due to long duration droughts becoming more frequent. We might yet have to bring water from elsewhere, no further pressure should be incurred.

The CRT was established after an atypically wet cycle, by people who were decidedly incurious about long term precipitation patterns.

We would barely have to cut agricultural use in order to completely cover the water needs of doubling the entire population of the US southwest. Yes, surface and ground water sources are "stressed", but residential use is only going to get more and more efficient on a per-capita basis. Even though growing population creates more absolute need, in as world where agriculture is flood-irrigating fields or spray irrigating alfalfa (losing an outrageous amount to evaporation), we should start with the "easy" problems first. Pay farmers to install drip systems, for a start.
