What’s your experience with these tube type systems like the Clemson pond leveler? The beaver is supposed to eventually give up and move on.

The RM I’ve trapped for is experimenting with this idea, but I heard on a pod cast that the beaver will find the current and plug the end of the pipe anyway. Sounds like there’s a bit of expenses installing it properly too.

Shakey, around here the beaver either plug it up after several tries and/or move downstream away from the device and cause issues there. It is unfair for the downstream landowners to take on that burden in my eyes but.... that is just my opinion. Beaver management is the answer.

I installed one, it worked for a while, there is maintenance to them. So it’s not an install and be done. You also have to have enough drop on the downward side for them to not be able to plug it up. Where we installed it the people downstream didn’t care they lived out of state and the property was of no use, rough land and the river was just past them.




My trapping partners prettier than most of yours

a band-aid that make more work

AGREED!

The place I put that they flood out a church parking lot, it does help but far from perfect. A lot of people involved in the decision on what to try and we charged a bunch.

Beaver deciver's as they are called come in many shapes & forms, but not a permanent fix by a long shot, they still have to be maintained depending on Beaver activity. Removal of the Beaver seems best.

they have there place,
the collection area should always be under water and elbowed up and out for head pressure....
A maintenance contract pays for a lot of fuel........

Looks like a ton of work for a half arsed fix. Down or up stream at this RM frequently means a different area along the drain or ditch.
Seems way cheaper to trap them, at least for the one municipality around here. The public works guy at the RM I trap in says he made his own to try out. The other RMs just don’t pay enough for even the locals to bother.

They work for spots where 2 year olds end up on a continuous basis year after year after their momma kicks them out of her compound.
A typical 2 year old generally swims down stream until it encounters a road with a culvert pipe under it.
From its perspective, it sees a a dam already built for it. It believes that all it has to do is fill that little hole and it has a new pond to live in.
But if the topography isn't right to make a wide pond after its done, it will continue on, never to return.
That right there is a hard beaver to catch since it'll never return. I work a few spots like this and never catch the first beaver. I tear out the dam and nothing fixes it until the next 2 year old gets kicked out of mommas place. Wash, rince, repeat, infinitum.
A beaver deceiver is the ticket for spots like that.

About twenty years ago the Mn DNR thought they were a good tool. I'm still digging pieces of them out of the culverts. I can't think of a single place they worked.

I fight with the remains of one all year. Water bottling plant put one in, and it is the only outlet of the lake. Eventually the natural debris built up around the cage enough that the beavers were able to detect the flow through the holes in that debris and then it was on. They built a square dam all the around it creating a coffer dam with a dry hole in the middle. So the company gave up and tore out the cage and shortened the inlet so the opening can be reached from shore, but it is under 2 feet of water. So the beavers plug it easily, and I cuss and spit and tear at it for a half hour every time new beavers show up and plug it.
And now, the company pays me to maintain their outlet, and to remove the beavers. They have nothing good to say about the company that installed the flow device, because they claimed it would be a one time expense that would solve the problem.

All of that said, I do think they have a place. There is a nature preserve that has a county ditch and I am bidding an install there at one specific location near a popular nature trail. But I have been clear with them it will require regular maintenance that the county will not pay for, and it may actually INCREASE the amount of trapping that is ordered by the county because as the beavers establish in the lake with the flow device they will kick out young that will go downstream and cause flooding. All of which ends up being good for me. Install the flow device, maintain flow device, remove beavers that move downstream. And no more trapping right beside the nature trail. All wins.

I’ve only seen 2 spots where the municipality tried them and neither of them worked. I’m going to clean one out tomorrow…lol.

I've been called to take beaver from half a dozen spots where these are and the beaver problems just get worse. Haven't seen one that helped more than a year yet

Buddy in Alberta installs them sometimes. They do have a use in specific circumstances, but have to be maintained.
