The Second Grade Pod is named for Lake St. Clair. In 1679 explorers from France discovered this small body of water that plays a big role in the Great Lakes System. They called it Lac Sainte Claire in honor of Sainte Claire of Assisi whose feast day fell at the time. Government officials changed the spelling later on to Lake St. Clair. Other people believe that the lake was named after General Arthur St. Clair who was the first governor of the Northwest Territory. Lake St. Clair is very shallow, averaging approximately 10 feet deep with the deepest at 21 feet. It plays a very important role as a busy connecting waterway in the Great Lakes system.
