You can start a syphon by placing the whole pipe in the water, letting
it fill, closing a valve on the end, lifting the end over and down and
opening the valve. A job for a mobile crane.


Like a Chinook, possibly?

If the outlet were placed at the bottom of the dam, there would be a
decent head until the reservoir was virtually empty.


Sorry - only about 34 feet. Beyond that, you would just create
a vacuum in the pipe as the weight of the water exceeeds the
atmospheric pressure needed to push the water up the pipe.
