Boco looks like a few problem areas I am in. When I am done I pull the dam out of the culvert also. Keeps a good relationship with the townships.

Under our contract we are paid a rate for returning the water to natural flow.It is mutual agreement between the client and the trapper.
There are the very odd circumstance when a trapper might pass on opening a dam for safety reasons.That would be a smaller culvert-very far in and holding back a very large deep impoundment of water.
I enjoy ripping dams.
Like I mentioned when done in a methodical way it is not hard,the water will do the work.
Dams that are difficult are old clay dams and not much water,or old dams with lots of woody growth.

These are not commond doing nuisance work because nuisance spots are attended to on a regular basis,since there is an immediate problem every time new beaver move in.
