Essentially, it is the installation of long pipe (say 10-20 feet) that extends 50% up the intake, 50% into pond, deep, preferably on the bed of both water courses.
Ideally the diameter would be 10-20 inches, but that is dictated by depth of water. Beavers will damn the junction, where pipe meets pond, but generally do not associate the ends of the pipe with water loss - which I believe they source by sound.

It's now getting ridiculous, I have to pull out their new construction every 2 days. If I don't the pond will dry up as the exit dam has a few leaks at the base, plus evaporation takes its toll. I can see the water level drop about a foot in a day when the beavers block the inlet. So does anyone have a good method of keeping the inlet open?

My second-hand understanding is that beavers generally *will* dam the pipe inlet, even though it should be fully underwater and those not making much noise. The supposed way around this is many small slits in the sides of the pipe upstream of the dam, and closing off the upstream end of the pipe..
