Thanks, for the help. Scott, if it were possible, could I take the cap off of existing tank and tightly seal another tank (rubber made container or 1-2 gal jug) on top - making a much larger gas container. Don't know why that wouldn't work if it were sealed properly.
F&C, Unfortunately, I buried the 1" pvc with the power lines (in the same hole) and it would be risky for me to replace the 1" with 2". As you mentioned, I don't think my creek could keep up with a 4", but a 2" is possible. I'm hoping for some rain, and then see how much water is needed, plus that should raise the creek back to where it was last year.
A few years ago, when I was building a larger lake, I went to a Fire Station in Atlanta and asked about buying some old fire hoses for water transfer - they gave me hundreds of feet of hose free! It worked great...


Just do it...
