The pond only gets about 3 acres of runoff. When they dug my pond they said there was a spring on the one end but its not a real gusher. The pond is 3 months old and has about four feet of water in it with another eight feet to get to full pool. My plan of pumping water from the lower pond is to help fill the pond and to keep it full during summer months. So I would be looking for a permanent setup. Also I forgot to mention electricity is out of the question at the lower pond. It's just way too far away. I will try to get some pictures up tomorrow. Thanks
