If you want to remove beavers the best device is a "pond leveling device."
I'm not sure I understand that. The dam already has a riser (what I call a spillway) with a pipe that sticks out the back of the dam and it has not deterred the beavers at all. Plus, this dam is big. It would take serious heavy equipment to put a 6' pipe through it!
Edit: See below. I'm an idiot.
They dam the creek leading into the pond from time to time but thats not the problem and I can dismantle these with a pick and shovel. The problem is that they are ringing all my hardwoods!

So far its just been gums, but if they touch my whiteoaks there's going to be a war (Bill Murray vs Gopher comes to mind

).
I'm assuming you want to drain the pond and then get rid of the lodges.
That's just the thing, I can't drain it. Old valve rusted away so there is no level control.
But, with the drought, both lodges (barely lodges, just big pile of sticks and their on the banks) are high and dry, entrances exposed.
That's why now is a good time to act. Plus, I could blow the cap on this well that I have at the same time that I blow these two lodges.
Beavers will keep return to a good spot so just removing the current population only buys a bit of time before the next ones show up.
This is definitely true. We've trapped them and shot them. Keeps them away for a while but they do come back. (But, we never saw any sign of them until about 5 years ago.) But, all I can do is keep plugging away
The pond leveler keeps them away.
Ohhhh, you put it in the
beaver dam! (I'm kind of slow.) But, that won't work. We've had them for 5 years and they've only built dams three or four times and they are very small.
Besides, why miss an opportunity to play with dynamite?
