"It's very likely a combination of if there are beavers in the area, as well as maybe the engineering of the dam itself or the materials used in the engineering of the dam", said Butfiloski.
Butfiloski explains the dam is built of red clay, which prevents water from seeping through. He also points out an important structural element is the steepness of the dam. The steeper the dam, the more likely a beaver can dig its way inside.
The water draining through the new trench has to go somewhere. In this case, it's Schwind's back yard.
"The beaver dam was a first for me; never seen one before", says Schwind. "And now here it is in my back yard."
D-HEC officials say the drainage trench seems to be working and water levels have dropped, but they haven't come up with a permanent solution.
