I need help designing a irrigation system. Specifically how to pull water out of a lake. I live on a lake, approximately 4' deep at the end of my dock. My property is 460' from the lake to the other end of the property. It is about a 10-15' gradual rise from the lake. Can anyone tell me the best way to source the water? I think I need a sprinkler pump to pull the water out of the lake and then push it to the yard. What are the advantages of a presurized tank? What size pump do I need? How many well points and what size? Any other advice would be appreciated.

I have put in several irrigation systems in the past so I don't really need help on the layout or sizing of the zones, just how to get the water.

Thanks,

Tim...
