To over water or to under water?

The golf course was the greenest that I can ever remember it this summer thanks to all the rain in June, July and the first part of August. Since the middle of August we have received very little rain and the course is beginning to show signs of stress in certain areas. When it comes to watering we like to keep it on the dry side so that play will be at its best. Certain areas of the course receive excellent irrigation coverage and other areas do not receive adequate coverage. Instead of over-watering around the greens, tees and certain areas on the course we substitute a few overhead waterings with hand watering or roller-bases. A roller-base is a hose that has a sprinkler head on it that we can move around to water areas that do not get irrigation at all or just do not get good enough coverage.
