If you’re not digging a swale, you should! Look up “greening the desert” project. Or look up permaculture. I’ve been wanting to do this for a while.

A Swale is a trench or depression dug on contour and it gives the water time to seep into the ground. It also creates a bit of a micro climate and depending on plants you can plant on uphill or downhill side. Very beneficial for high volume low frequency rain event locations.
