Pump to get 15' head with ~600gph

[aviator79]

Because I cant put my filter near my pond I can only think to put it further up a hill on the other side of the rock wall I built. I think it would have to be able to flow 600-700 gph at 15' head. Any recomendations?
Thanks

nevermind, I am going to have to figure out how to do this differently, I guess doing a lower profile filter right behind the pond.
