Drainage is an important consideration when building anything. When it rains or snows the water eventually flows downhill. If the downhill is blocked by a road you need to place a culvert to drain the water under and past the road.
This year we have a new issue. The culvert froze up and created a similar pond to the one above. I have been trying to figure out how to clear ice from inside of the culvert but short of having a high pressure water system that can also heat it up I think I’ve just gotta wait it out.
One nice advantage of having the uninvited pond is the killer night shot.
