As the property owner, you are responsible to maintain the Watercourse. This means keeping it free of trash, debris, excessive vegetation, and obstacles that could block the flow of water. You also have the responsibility to prevent pollution and contamination of the water flowing through the Watercourse.
A Watercourse is a stream, river, brook, creek, channel, ditch or swale where water flows on a continuous, seasonal, or intermittent basis. A watercourse can be natural or manmade.
