We put together a syphon device using 6 inch PVC pipe and it worked very very well. It took us a while to get it going (its very hard to get the air out of the line since gravity will push the water back down into the lake on the lake side of the syphon). Our lake is about 8 acres and we pulled the lake down about 8 feet in less than one week. If you have a way to use a pump to charge the syphon, I suppose it would be easier to start. We filled the line using 5 gallon buckets thru a t-joint at the top on the syphon. We capped both ends of the syphon and unscrewed the caps at the same time to start the syphon. It took us about 4 tries to start the syphon. Once it started, it shot a solid 6 inch stream of water about 6 feet. It was coming out with such force that it would knock you down if you got in front of it. One thing for sure, it will pull alot of water out and quickly.
