We use an airlift to clean out a sunken boat. The flexible hose had an air hose connected to the suction end. The discharge end was just placed over the backend of the work platform. In your case you could just place it over the pond bank. The air and mud will be discharged there. Cecil

6 to 8 feet above water surface? That is a bit... Try a 6" diameter PVC with an air line to about 1 foot from the bottom. Use a volume control air valve that you can adjust until you get the best flow. Run the air line down the out side of the PVC pipe and have the air exit in the center of the pipe. You are about to make a mess... ya think? I would run the PVC pipe fairly vertical and let the exhaust spill over into a much larger pipe that slants down hill out of the pond. ... or into an aqueduct. The more vertical the lift pipe the more velocity you can expect from the rising bubbles. This could be one of America's dirtiest jobs. ...good luck! ...be sure to thank the Admin for the "new" function to see this sketch..   The worst suggestion of your lifetime may be the catalyst to the grandest idea of the century, never let suggestions go unsaid nor fail to listen to them.

Thanks Randy, the 6-8 feet was from bottom of pond so lift about 3 feet above surface. Sketch has given me some useful ideas, just need to work out how big a compressor I will need.

Welcome, ...as for compressor.... not so big. A little air makes huge bubbles in three feet of water. You may have trouble lifting three feet above a three foot water depth.
