My 45 year old 4 acre lake in East Texas has many tunnels in the dam throughout the area above water. I am pretty sure that it is beaver, but locals say it is most probably nutria. Is there any surfire way to tell the difference? I know beaver are there, I have actually seen them, but not the nutria.
Secondly, Opinions welcomed about my plans to repair dam. Using a backhoe, we are going to collaspe the tunnels and backfill. Then regrade the top of dam and water side. I am thinking, that even if I get rid of the critter problem that they'll be back, so I was going to line the water side of the dam with used 6' tall chain link fence. Any thoughts on this method?
Thanks to all who respond!
