Officials in the Village of Mukwonago are hoping they can find a place to relocate a family of beavers. Otherwise, the animals may have to be killed. The beavers have built a dam near East Wolf Run which is putting some nearby waterways at risk. Fields near Interstate 43 are flooding. Village leaders are also worried about the effect on stormwater retention ponds which are filled with contaminated water. If the dirty water is forced out it will impact nearby creeks and rivers, dumping untreated water into the Fox River system. The D-N-R has given the village several options to trap and relocate the animals, but no decisions have been made yet.
