Final answer:
In the sport of golf, water hazards are indicated by yellow stakes and lines as a visual guide for players.
Step-by-step explanation:
In golf, water hazards are indeed designated by yellow stakes and lines. This is to provide a clear visual representation of where the hazard begins and ends. A ball that crosses the hazard boundary is considered 'in the hazard', and different rules apply for play. It's important for golfers to understand these visual cues and consider them when planning their shots.
