As it turned out the two incidents were unrelated, but in the same area. The water coming out of the ground was caused by a plugged overflow pipe coming from the pond. Bill pulled a couple 8-10" chunks of log out of the pipe, along with the debris caught behind it, and the water was flowing well again.
The sink hole was caused by a rotten piece of galvanized pipe. As you can see in the picture, a good portion of the pipe had rotted away leaving the soil under the pipe exposed to some erosion. All things considered, it could have been a lot worse.
