I'm with DD1 - you run into problems with certain trees/stumps when your ratio is high. If you have a good size BOW and few stumps/trees you likely won't have trouble.

And I can tell you that within a couple of years the issues resolve themselves anyway. One finger on my large pond was completely chock full of Oak trees when it filled. Within a couple of years of filling there were fish throughout that area, and still are today.
