I need to drain the pond to refill it with clean water.

Where will the old water go?

Siphon? Is your pond higher than any place else on your property?
Or
Could you just run more water into the pond until it has displaced the
old?
Portable sump pump
Cheap electric models at the big home centers $50 or so, maybe rent for
a couple of days.
Gas - more expensive - if no electricity
