Just an FYI. The flow in the Guadalupe River near Guadalupe State Park is fantastic and water clarity is really good
Just a word of warning for those in Canoes. Be careful. I seen two swamped canoe's this weekend. One was totaled, the other was in the process of being recovered
If you choose to run the river via kayak, you should not have any problems.
Good luck, See you on the water.
