Sadworld,
Are you sure you pond is 15 to 17 feet deep at 100 by 50 feet? My trout ponds drop almost straight down and at about 90 by 40 feet and they are only about 9 feet deep. Have you actually measured the depth?
This mostly drained pond is only 9 feet deep. Looks much deeper doesn't it?
BTW an easy way to measure the depth of your pond is with a slip bobber rig. Put enought split shot on the end of your line that will get it down fast but not enough to sink the float. Keep adjusting the slip stop knot until your bobber (float) sets on its side. Then measure from the end of the line to the slip stop knot. What's nice is you can cast this anywhere in your pond to find different depths.
