Thanks Doc, like I said I am new to pond building, my lake is 10 surface acre's, it is feed by two wells that produce 75 gpm each, my water temp is controlled and the ph is 7.0, when I said acre, that is land size, the fathead minnows are spawning. I also have 20 koi's that is between 4 to 6 lbs. and also 20 largemouth, which I hope to see spawn in the fall, the largemouths are from 4 to six lbs. So add that up to the previous total and that is my fish population. I would also like to know if brown trout can be added in october. my location is at the blue ridge mountains in N.C

Cecil, hope you enjoyed your joke
