...“The area in the lake where the island was built was a shoal or small rock pile just under the water surface,” said Art Techlow, Wisconsin Department of Natural Resources Winnebago system biologist.

“We needed at least 19 inches of ice for the trucks to drive on safely. Then they could only carry half loads of materials to the island spot.”

According to Techlow, the construction of the island took 62 truck loads at 10 tons per load and seven days to complete. When the ice melted this spring, the materials sank around and above the small rock pile creating an island for the birds.
