(Lake) Superior Pursuit Available

If you live anywhere near Lake Superior, you’ve heard the brag: Lake Superior is the largest freshwater lake by surface area. It’s second only to Lake Baikal in Russia for volume -- the amount of water it holds.

Well, did you know it’s actually THIRD in volume? It ranks behind Baikal and Lake Tanganyika in Africa. But never fear, Lake Superior is still big enough to hold the water from all of the other Great Lakes, including three more Lake Eries.

These facts and more can be found in a free brochure, Superior Pursuit: Facts About the Greatest Great Lake. The publication was recently updated and produced by Sea Grant with help from the Lake Superior Center and the Western Lake Superior Sanitary District in Duluth.

“This brochure is for anyone who is interested in Lake Superior,” said Marie Zhuikov, Communications Coordinator. “It’s written for both U.S. and Canadian audiences, with comparative measurements in metric and English units. It provides a ton of Lake Superior facts at your fingertips.”

To order your copy, look on the publications page and our free order form, under the travel/tourism category (item S4). The brochure is free unless bulk quantities are ordered.
