Dig a hole and you will find a stream. It is not just coming out moist. There is a stream in there someplace and it may be and probably is a trickle. Moist trickle Karl. Take a 4" piece of plastic pipe and push it in around the trickle and trap it. Put clay or a bag of cement and seal it and it will come out the end of the pipe and then do with it as you want.
