U launch in anuahac and the salt water barrier?
When I take my boat, I put in at the Wallisville Project launch just south of the saltwater barrier. When there isn't a lot of fresh water coming down the river from up north, the barrier is kept closed. It only opens up on the top of the hour. It was open last Saturday.
We went in my brother-in-law's boat, so we launched from his neighborhood boat launch on Cotton Lake.
There is a launch at the I-10 bridge but with all of the recent rains, it has silted in. You could probably get a jon boat out of it, though.
