It was hard work. No fill port at the top. It was a pretty short climb from water level to max elevation as the dam was breached. I put the bottom end up in a ladder rung, then went to the pond and dunked the end and lifted it overhead numerous times. That lifted water over the top and it filled the back end. Once it started spilling out the lifted back end, I put the draw end into the pond, went to the ladder and shoved it over. Not fun solo in cold water, but with a breached dam, you are very motivated. I'm not sure it was ever in full siphon mode, but it did move a lot of water. I put 3 of them in as it was raining hard and water was flowing out the breach. I was determined to get pond level down ASAP.
Edit: Found the old thread with some pictures.
