The Dept of Conservation in Mo (at least my agent) told me a 10:1 ratio is what he goes on. I was trying to fill a one acre pond, but only had 8-9 acres of drainage. Unusually wet weather this year has my pond full, but the two previous years were drought years, I was almost 5' down on a one acre pond. (I do have a small leak, and trees right at the water's edge) So keeping it full is not a given.
It's been full, and or running out the overflow pipe off and on since filled in early 2015.

Our expected annual rainfall is around 35".

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.
