Just some thoughts here. Wait for a professional opinion.
If the other pond is 20' lower, how about a siphon? You could use a pump to get it going, but then it is all free after that.
Second idea, but more costly, would be put a pipe thru the dam at the water level you would not want the water level to go below in the first pond. Install a shutoff valve and open it when you want to fill the lower pond.
Welcome...
or is this just a one time deal?
