FishinRod, no need to stress about extra deep pond, the YP will do fine where you are at. It must be a myth that they need deep and cold water, as long as you have don't aerate to mix all the water to 80 degrees or warmer they will be fine. I have a shallow pond with a little bit of stratification of temps so that at the 8-10' mark there still is a bit of temp change and they do fine. I try to aerate at night in the warm summer months to try to keep surface temps down a bit.

Go for it!
