How Big Was the Fish that Johnny, Jargo, and Tooter Caught?

We are talking about the one they caught in the little pond on the BarNone

 Ranch on one of Johnny's famous juglines! In this pond, which is only 20 feet

 across, there grew a cattail exactly in the middle and it stuck it's little head

 above the surface of the pond exactly 1 foot.

When they put Johnny's jugline in the pond, and caught a huge fish, it

 wrapped the line around the cattail and pulled it over so that it just touched

 the edge of the pond.

Now, if their fish

weighs 1 lb for every 5 feet of depth in the pond, how much does their fish

 weigh, to the nearest ounce? Post your answers on the Guestbook for the
