We have problems with water draining from our yard. Across the road behind a neighbor's home we found this beaver dam in a canal that is suppose to handle all the run off water from our homes and fields. They had the water in this canal pretty well stopped up. In the top picture in the left edge you can see a tiny bit of my husband digging away at the clog. In the bottom, his dog, Missy is checking out the dam. She walked all the way across, sniffing as she went. We need trappers.
