Great Lakes Geography

6 | Introduction to the Great Lakes

Lake Erie highlighted in yellow.

Lake Erie is the shallowest of the Great Lakes (averaging only 62 feet) and overall the smallest by volume. Erie is also exposed to the greatest effects from urbanization and agriculture. Lake Erie measures 241 miles wide and 57 miles from north to south, and has 871 miles of shoreline. Because it's not as deep as the other lakes, Erie warms repidly in the spring and summer and is frequently the only Great Lake to freeze over in winter.
