Dan Small fishes for walleyes on the first day of spring near Lake Pepin with guide Denver McKinnon and Meredith Evans. In an archival segment from 2006, Deb Wolniak visits a great blue heron rookery in Ozaukee County and talks with former Department of Natural Resources naturalist Bill Volkert about efforts to save the rookery. Finally, in the first part of a two-part series, Dan meets with John Seamans of Sheboygan Falls, Wisconsin, to learn about his restored Adirondack guide boat.
