The biggest of the culverts in our area of responsibility is just north of the start of the new road. It carries a large amount of water from a lake in the southwest. This lake has a beaver dam which can affect the volume of water. The water has overflowed the road by about 2 feet at least on one occasion but the culvert is well constructed and was unaffected.
Thanks to wolves, the beavers have not been a recent problem. But, there has been some erosion of material around the outlet of the culvert which is working its way back towards the road. It will require some large boulders to slow down the erosion. Not an immediate problem, but it will require attention in the next few years.
