I have built a pond that will be about 1.2 acres once it fills up. Now it has about 1' to 3' of water and it is very dirty. I had all the ground and dam hydromulched and the grass is about a foot tall but it doesn't go down to the water line. Like everybody with a new pond, I would like to start introducing fish, Is it too early to add some flathead minnows and mabye some bream? I am located just north of Houston in lower Grimes county.
