But don't leave anything of value in your truck. Or you can launce out at the Lake Wood RV Park. That puts you in the river below Lake Wood dam. call GBRA first, not sure if they are open yet.
I was there last year and the ramp was completely out of the water and the lake bed was dry. The dam had broke several years ago and to my knowledge was never fixed. Again it has been about a year when I saw the ramp.
