I don't understand the reply either. The link shows clearly how it works and that it's about managing water levels, not pond elimination. Many times these ponds are secondary, and extra care (in some case by regulations) is needed for primary ponds where beavers need deeper water to survive through winter.

Another solution I have seen is the A-frame trap which blocks the beaver from damming the culvert and takes longer for them to build around the trap. Even when they do, which they will, when the water rises it spills over. From a maintenance perspective, they are easier to clear than clog in the pipe.

As a species we had better get smart about coexisting with these creatures. Some say the water issues out west are related to the extermination beavers, and their reintroduction will do much to replenish ground water and create natural reservoirs.

But that doesn't mean we we should antagonize the humans by insisting we allow roads to wash out and flooding to occur. We need compromises.
