I put 5 in my pond this year in May as Theo said my pond is also a little under 1 acre. I have not seen any difference this year but I was told that would be normal. I am interested to see if this spring they keep up??? Since I put them in there in may I have not seen them, but I have quite a bit of Chara and pond weed so there is a lot of places to hide right now.

The only difference between a rut and a Grave is the depth. So get up get out of that rut and get moving!! Time to work!!
