Rule 26

Status of Shallow Concrete Ditches

Q.  We have shallow concrete ditches that run throughout our course that only contain water after a good amount of rain. Should these be played as immovable obstructions or water hazards?

A.  If the concrete ditches are not part of the architectural design of the course, then they should be treated as immovable obstructions through the green and Rule 24-2 applies. This is usually the case. However, if the ditches are included as part of the architectural design, then they should be defined as water hazards or lateral water hazards and Rule 26-1 applies.
