I had planned to spend the day enjoying whatever the remnants of Rosa brought us and after checking the rain gauges, radar estimates, streamflow gauges, and forecast for the day, I decided the area south of I-8 between Casa Grande and Gila Bend was prime time. Ideally I would have liked to climb Table Top, but I had a good suspicion I wouldn't be able to get across Vekol Wash toward the end of the drive to the trailhead. I figured I'd be able to see it from the interstate and make a decision there.
Maricopa County Flood Control and USGS each had scientists on site taking readings and observations in person. I chatted with each for a bit which was interesting. The flow was just over 2000cfs when I was there, but had receded from 6000cfs overnight. That's an impressive flood for a dry wash in what appears to be a perfectly flat valley!
I spent the day hiking elsewhere and then returned six hours later on my way home. The flow was down to 200 cfs, but looked more impressive than that. The level was a solid three feet lower than earlier in the day, which at a width of 100 feet to over 400 feet is a pretty substantial amount of water! It was fun to witness this one in person.
