They won't "live" in a half sunken drainage culvert. They need a dry area to sleep in, and that typically is an area that has an underwater entrance to offer protection from terrestrial predators. Yes, they will walk across dry land to get to another BOW, but prefer to swim. They swim to escape from predators and that is hard to do on dry land. Watch that the grate doesn't plug during a high water event and cause the pond to overflow.
