Two years ago we built a one surface acre pond here in mid Michigan. The pond is 12 foot 4 inches when full. It has some springs in it. The first year, we planted 200 rainbows in November. They did well until early June of the next year. Then we lost them even though the water temp didn't seem to be that warm. I believe the problem was that we were aerating 24/7.
This year we planted another 100 rainbows in the spring, aerating only 3 hours a day. We also added 2 gallon of blue dye. So far even though the summer was very warm, most all of them have survived. Even though the pond is only at 10 foot deep this year, it seems to be doing much better.
We are going to put 100 brook trout in the pond in the next week or so. Being new to this pond thing, I am open to any advice any of you have. Thanks
