I was joking with a friend that we should open a diving quarry where we live in SoCal. While our diving can be great, there can also be long periods where you can’t dive because of swell conditions.
That made me realize that I don’t actually know how quarries maintain their water levels. Are they generally below the line of the local water table?
Perhaps most importantly, if I rent a backhoe and spend a long weekend digging out a 200x200x30-meter hole, how long do I have to let my hose run to fill it up?
