A friend depending on what time of year will try to trap them IF we can find the den. Next to impossible when it could be anywhere in about 26 miles worth of canals. Normally it's a tear out the dam and then campout and wait for them to come back to fix the hole. A truly amazing animal for what they can do but a real PIA when you're in the business of keeping water moving. In flood conditions we have to patrol the levees daily to keep them and other burrowing critters from trying to make new homesteads in the side of the levees which obviously can be catastrophic.
