Morning update: Decided to make a bubbler fountain for the artesian well water to enter the small pond. The trick was drilling a 3/4" hole 12" through a granite rock with quartz in it. Decided to try the cheap route first by purchasing a carbide bit and using my 3/4" hammer drill. After buying the bit from Menards this morning, I saw that the maximum masonry bit for the drill was supposed to be 9/16". Well, I already had the bit... After 2 hours of 30-second cycles followed by water wash-out and drill cooling, I have a very nice 3/4" hole through the rock. When it dries up, I'll get it going and post pictures.
Afternoon update: A plastic 3/4" barb to 3/4" male pipe fitting went into the bottom of the rock hole (with caulk) nice and tight with a rubber mallet. Now the rock just must be placed and hooked up once the caulk dries (and the ground dries up from all the rain).
