As a superintendent, my first consideration is always safety. The safety of golf course employees and guests is paramount when making decisions for the course. Weather in Texas can be unpredictable. Playing in the rain as long as there is no lightning can be enjoyable however, unexpected things may happen due to standing water and over saturated ground conditions on the course and closure has to be considered. I am also an avid golfer and I understand the player perspective of wanting a course to be open when I want to play a round of golf. As a superintendent I have to consider how extreme wet conditions can affect safety of the players and employees on the course. Some of the issues we consider are not visible to the naked eye and may not seem transparent.
Sometimes you might see the sprinklers on right after a heavy rain and wonder why they are watering? This can be due to many reasons that do not include the need for irrigation. Lightning or rain can sometimes damage irrigation satellites and testing needs to be done to determine repairs. Also, after some heavy rains it is necessary to apply products to the grass in order to maintain health and aesthetics and these applications require watering to complete the process.
Just remember that communication is the key! Anytime you have questions or concerns about the course you normally play asking the superintendent is a great way to get information straight from the source.
