Me & Shakey will come out...stand on the culvert...fire up

A fat one...and come up with a plan ...

Pretend I didn't get the call!

Is there a set I can use in the entrance? This beaver acts like he has seen conibears before.

This sounds like one of those deals where you tell a bunch of your buddies your having a roofing party in the middle of July. Maybe if they`re not too wasted, drinking beer in the shade, they`ll be able to catch you when you pass out and roll off the roof.

There are a couple really good ideas here. Snares on poles at the entrance of the culvert seems viable. I remember a roadside pond I trapped a bunch of years ago when we still had some water. The water level was almost at the road and dropped right off like you describe. Maybe I was able to scratch a little dug out into the bank that acted as an entrance to a handful of mud, a very low key castor mound, a very small amount of lure. I don`t want an aggressive response, more curious. I was standing right at the bank and was up to my tits in the waders and there was nothing to work with, so I told the Chesapeake to go get a stick. Water and a stick!?!? Will do!! He comes back with this little sappling, which being the 150 lb dog, he would usually come back with at least a good section of tree. So I cracked off pieces of the stick, shove them into the back, you know, make a ledge to impale the trap on, maybe 3-4" deep. Buried and staked the rod as normal right next to the trap. It works, but not my first choice. Can you take a couple T bars, shove those in the bank and adjust those T`s to pin that trap in place?

To tear it out think earth anchor. Only longer with enough cable or rope to reach out of the culvert on the down stream side. You would have to rig up some kind of driver long enough to punch thru the dam. And get the anchor to turn over against the up stream side of the dam. I would start with something 8 inches long securely attached to rope long enough to get out of the culvert. And start pulling. I've never tried this. It's just an idea that crossed my mind while reading this. Should be safer if it works.

This one is holding a lot of water back. My thought I pull the wrong stick I might end of quite a ways down the creek without a paddle.

You should be able to get in from the low end.
I often put on a pair of running shoes and just wade in and start ripping the dam,after the beaver have been removed of course.
I remove all the long sticks from the foot and back face of the dam before I start letting the water go.After a few pulls with the beaver rake the whole dam starts moving-thatis when you swim out.
I prefer opening the big culverts the small ones are risky going in from the low end.
A 4 foot culvert is no problem.
