From the brochure:
This sculpture is a three dimensional sculpture that is made out of tin, to form seven fish. The fish swimming under the water scene include a small mouth bass, walleye, catfish, northern, salmon, and bluegill which measure thirty feet long. Jumping out of the water is a 70 foot long rainbow trout.
This was one of the newer sculptures, but it was in the worst shape. Large pieces had fallen off several of the fish. But strangely, it was also the only one that we had to share with other tourists.
