"Under the Ice" takes you on a journey to the icy waters of Wisconsin's Lake Winnebago. It starts with the opening day of the sturgeon spearing season and ends with fisherman showing off their catch. 

In between, learn why more than ten-thousand fisherman spend hours on a frozen lake for a small chance to get a sturgeon. Some fisherman wait decades before they even see a sturgeon. 

Experts from the Department of Natural Resources explain the genesis of the sturgeon season and why this fish can only be harvested with a spear. Fisherman explain why they can't get enough of this prehistoric fish.
