Port Huron in St. Clair County, Michigan — The American Midwest (Great Lakes)
Learning from Lake Huron
Lake Huron's basin was formed by glacier movement over 20,000 years ago. The lake was created when melting ice filled the basin gouged by the glaciers. Lake Huron took its present shape around 3,000 years ago.
Lake Huron is the second largest Great Lake, based on a subsurface area of 23,000 square miles. It is the third biggest lake based on volume, behind Lake Superior and Lake Michigan. The surface of the lake is 577 feet above sea level with an average depth of 195 feet, and a maximum depth of 750 feet.
In 1970, the National Oceanic and Atmospheric Administration (NOAA, pronounced no-ah), became a scientific agency within the United States Department of Commerce to give better protection of life and property from natural disasters. NOAA's mission is "to understand and conserve and manage coastal and marine resources to meet our nation's economic, social and environmental needs."
At the Fort Gratiot Light Station, NOAA measures temperature, wind speed and barometric pressure from the top of the tower and uses the information to predict weather changes. The gage house, seen in front of you, measures water
