A method of siphoning water over dams by means of a siphon. The siphon is started by closing both ends, by means of a ball valve, gate valves, check valves or other means to seal off the ends. The siphon would have a vacuum tank on the top. Water could be pumped into the siphon at any point or filled through the top of the vacuum tank. Some models need not have the vacuum tank. To start the flow the vacuum tank would be sealed and the ends opened.
