I run the river from Lake Wood to Oak Forrest Dam in my bass boat. Keep your eyes open and stay in the channel.
You can launch below Lake Wood dam at the GBRA Park. There is no take out at Gonzales except kayaks. Yes, it is easy to get to the confluence. I haven't done the confluence run in probably 30 years, but it is about 5 hours by kayak if that helps.
Snowflakes and entitled brats will be the doom of America!
