We went out to Guadalupe River State Park on a recent outing. I knew this park would be dry, but when I saw the flow rate posted at the park store I knew it was worse than I thought. The sign said “0 feet/second.”
There’s no tubing, very little to swim in, and if you’re fishing, bring the small hooks.
It wasn’t more than a few inches deep on avg through this area. Upstream was a little better, but it wasn’t a long stretch of waist-high water and then back to near dry conditions.
Above you can see where the water has carved into the rock along the river. This was probably a good 25 feet lateral and 15 feet above the current water level. Did I mention the river was low?
