I put two pumps in one well casing. One 12GPM for the home, and a second 20GPM for the pond. This was much less expensive than drilling a second well.
My pond came 10 years after building the home. Fortunately I had a "smart" well company and the water capacity flowing into the well to support the second pump. The pond pump is positioned above the house pump so if the water table should drop my home does not run out of water (never had a problem with either).
Wisconsin code does require that there is an "air break" between the pond and the well so there is no chance that pond water can back flow into the well. This means that the well needs to be above the level of the pond.
