I might be able on one of the inlet areas. I'll have to build a dam and then cut a ditch to the side around the big pond. The other area has a lot of trees and is much wider.
Definitely worth the time and effort to do it. I had to do this on mine, and saved me days, if not weeks, of pumping. Still had to pump, just not nearly as much. Now if someone else is doing your excavating, they may have a huge pump where they will dig a hole where it is coming in and pump non stop till their done working.
As TJ says, siphons are great, but you need to have the outlet lower than the inlet. Not always possible.
