Is it a proximity issue, and availability issue or something else?
Yo Nude! (Sorry, just had to do that!)
In answer to your questions:
Yep, yep, yep.
Well, I hope that I helped!
Man, must be too much non-alcoholic spiced cider! Got to get serious for a minute (but just a minute). As you can see the quarry is completely man-made. Some lakes are also man-made but not for the purposes that quarries are created. Quarries that flood and become water-filled do not have the same environmental issues that lakes have. They are privately owned (I suppose it is possible for some to be public, but I do not know of any off-hand) and that means that there is someone controlling the use.
Generally, you don't find a lot of water sports being conducted on a quarry. Fishing and diving are the 2 most popular activities and fishing
only is the quarry was stocked. There will only be certain fish in quarries because of the controlled environment. I am
planning a trip to dive a quarry in TN in March because they have humongous paddlefish there. Imagine diving next to 7-8 foot fish in fresh water at 60 feet!
Quarries generally have greater visibility. I think it has to do with lime in the water (if a limestone quarry - which is popular.)
As mentioned above, cool stuff to check out! I dive a quarry here in Estonia that when it was flooded it overran a prison - buildings, cells, guard towers, etc.. Pretty neat, just watch out for the concertina wire walls!
Most people live close to a divable quarry. And since they are usually privately owned arrangements can be made to access the water just about any time (Hey, who doesn't want to make a buck by letting folks play in the water!)
Also, consider the surface are to volume ratio. Quarries are generally much deeper than lakes of comparable surface area. The deepest body of water in Ohio is Gilboa (mentioned above). They even have a passenger jet sunk in that quarry!!!
Hope that helps!
Oh, one word of caution: on the negative side for some, quarries are generally colder (spring fed).
