I don't know what caused the streaks on the concrete. Makes it look like natural rock, not industrial concrete. It's not sunlight reflecting off the water, because it doesn't move.
I was quite pleased with this photo, thinking that most people wouldn't have noticed such a simple but beautiful image. Then I saw a friend who had just started in photography, take the exact same shot.
