Played 18. Course was soaked, standing water relief on every shot, except there was nowhere to take relief without standing water. I was surprised the course was even open (forgot to cancel tee time within 24 hours and didn’t want to get dinged with a no-show charge).
Played 9-3 punch shot on every swing. Had a nice low pull fade / straight fade ball flight with this swing, which I wish I could replicate with my full swing. Putting was pointless due to water on the course, so just picked up once I was on the green.
In the example from my course (not OP), it’s not a french drain - but does divert water to a catch basin at a low point. Played in an atmospheric river storm this morning and this is what they look like when it’s raining (today was insane rain, not normally this bad).
