Thank you, esshup! We are in NW Oklahoma, so we are between those two numbers but likely closer to the 65". Thanks for finding those stats for me. (I'm not lazy...just didn't know where to look!) smile

Our pond surface measures about 1/2 acre and the deepest point is 12-15' deep when full.

As for the well casing and screen---ummm, I'll have to ask husband those questions. And I'll have him figure out the approximate run, also. Other than getting the water to the surface, the topography to the pond is all either level ground or downhill.

I'll certainly pass along your recommendations on the pump and pipe size! Thank you BUNCHES! I'll take pictures as we go...
