Paddled the Tywi from Llyn Brianne down last Sunday (29th Jan). There's a tree across a rapid about 2/3rds of the way down to the bird sanctuary. (not sure of the name of the rapid, not a regular paddler of this river). We tried to move it but didn't have the manpower.
The lead-in is straight so you'll see it before you get there, and it's an easy-enough portage, but thought I'd let folks know anyway.
