Great, thanks Esshup. The ravine is lower than the pond so i will try the siphon method you mention. I have plenty of land and clay on site and moving any muck to the backside of the dam into the ravine should work as well. I understand the core trench and agree. Any idea how long it will take for the pond to dry out enough to get equipment in there? Thanks alot for your reply
