Approx 12-15 feet from pond to the pump-mostlly level but some up and down (the piping does not go through the side of the fish pond but up and then over into a crawlspace). From the pump area through fifteen feet of piping to a hgt of 10 feet or so above the pump to a small area and then over the waterfall.

you need a pump that will lift the total height and pump the number of gallons per minute that you want. you will need to do some research to find the right flow rate.
Depending on the size of the waterfall, you can determine the amount of water that will look excellent by supplying it with water from a garden hose if it’s a small waterfall, or by dumping large bucketfuls of water over the falls, measuring how long it took to produce the desired effect. It may help to have an assistant do the stopwatch stuff.
For example, if a 5 gallon bucket of water dumped over the falls in 10 seconds looks excellent, then that works out to 5 x (60/10), or 30 gallons per minute.
If it’s a small waterfall, you can simulate the flow using a garden hose, and then time how long it takes to fill a 1 or 5 gallon bucket and compute the gallons per minute from that. Then you’ll know how many GPM your pump needs to reproduce the same look.
I suggest you go to a website like “watergardens.com” and look at the pumps and waterfall kits they have available. Sites like this also give technical advise on selecting pumps, piping, etc.
This is what I did and it turned out just fine.
you need to know how much water you want to have running over the water falls and how long the run is , its like a swimming pool, the larger the pool the larger the pump to keep it flowing , its how many of gallons of water have to turn over in an hr. , you could get a pool pump it has a filter for say. and it might just work.
