I think the point about it being natural was not saying it wasn’t man made but that it is not a treated body of water with a concrete bottom like paradise bay.
yarp! That’s what I meant I never thought about the rigging having to be above surface during maintenance. Unless it could be done at night? Either way, something permanent and fixed so the lake has a large number of lighting like world of colour would be super impressive. The start of the world of colour show always impresses me when the fountains are minimal, but the lighting travels across the water.
