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.

9 yr old pond, 1 ac, 15' deep.
RES, YP, GS, FHM (no longer), HBG (going away), SMB, and HSB (only one seen in 5 yrs) Restocked HSB (2020) Have seen one of these.
I think that's about all I should put in my little pond.
