Trent.....that YouTube video is exactly what I plan to do except rather than let the water run out at the bottom of the dam I plan to run the PVC pipe into a stock tank and control the flow with a ball float valve.
I think once the siphon is up and running it can be turned on and off at the stock tank as cattle drink water and the tank level fluctuates. If the siphon isn't broken by air getting into the pipe I think it can stay up and running for as long as necessary.
Also is very portable which I need as cattle are moved to different pastures. Trying to fence them out of the ponds I am managing. Thanks for the video link. BM61
