John good suggestion. my highest pond C has the smallest water shed. My lowest pond and largest pond(about 12 acres has the largest water shed whith continous water through it usually year in and year out since it was constructed in 1993. the middle pond B has a modest water shed and that is the one I want to pump water up to from the largest pond. I fill pond D or the duck pond about 2-3 acres which sits just behind the big pond with an 8 inch pipe that runs through the botton of the big lake from about 200 feet out and under the dam and through a regular 8 inch cast iron gate valve down 14 feet in the bottom of the duck pond. other than rainfall the duck pond has very little run off. Should have used that pipe and a tee to constuct some way with another valve to connect to a ram pump or turbine wheel to produce energy. Wasnt even thinking at the time. have about 30 feet or more of head . Would be a lot of work and expense now to rework to access but is do something that could be done but I had to drain the duck pond again.
