Please provide any additional information below. Attach a screenshot if possible.

Waterway=dam should be excluded from this test, because it's not a "normal" waterway where water flows, but a building stopping the water. And normally a dam is a little bit wider than than the water area he is stopping. In this case you have a stream and a second used as "overflow" around the the dam.
