This photo shows are challenges with a single row irrigation system. More water is delivered around the sprinkler head and it gradually decreases the farther you get from the head. This is #1 fairway. You can see the rough is getting essentially no water. The only way for us to get water to the rough is by dragging a hose over and hand-watering the rough. Of course, this requires a lot of labor when we do this on 18 holes. In order to keep the peripheries of the course green, a lot of work goes into it!
