If water supply is a big problem in the States, can’t we effectively store stormwater in some way and replenish our supply?

I mean you absolutely can for personal use, except in some states with some minor restrictions from older water rights issues. The idea being that if you collect rainwater you are taking it from someone else it would have potentially flowed to naturally. Its rather outdated logic now though, and most harvesting laws have been repealed.
The problem though is that the main reason we have water shortages is because of agriculture. Makes up something like 70% of water use. Crops (including those we feed to livestock) can need tons of irrigation, and virtue of being an open field are already collecting quite a lot of rainwater.
Like if you zoom in on a random spot in the US that isn’t a national park or desert or mountains it’s just fields back to back to back. There’s just no empty space near good farmland for supplemental rain collection. Cause if there were they would put a farm there instead.
