We had 4.5� and it brought my pond up 2�. I still need 3� to fill it, and those last three feet are even more water. I don�t think 5� will do it for me.
My ratio is close to 10:1 with almost 10 ac filling a 1 ac pond. 50% thirsty trees and 50% thirsty beans. All the rains we had from March until a little over a week ago, we had zero runoff. Maybe if we blacktopped everything I could get better results. Haha..
Every little bit helps though.

12 yr old pond, 1 ac, 15' deep.
RES, YP, GS, FHM (no longer), HBG (decreasing), SMB, and HSB (only two have been seen in 5 yrs)
I think that's about all I should put in my little pond.
