Excerpt: Saturday, citizen scientists throughout the U.S. gathered at watersheds to celebrate National Lakes Appreciation Month by conducting similar studies. Vincent Kaping, 10, of Felton, said he was surprised the disk wasn’t a more complex tool. He thought it would have some filter or other contraptions attached to it. “I was thinking that it would be a machine,” Kaping said. He took two readings; both were about 6 feet of visibility marked when the disk disappeared in the green water about midday.
