This in response to James.
I was at Bayou Bienvineau on the 24 of this month looking to find out if the locks are navagitable. Talked to a shrimper who has been navagitating through the locks that are being repaired. The opening is small and the current is strong at times and at least one boat has been turned sideways against the structure. I intend to go that way on Thursday march 2nd. Will give feed back.
