What is the average annual water temperature of each of the Great Lakes? I've only found the one for Lake Superior, and have Googled and searched NOAA's website. I need this info for a book about the Great Lakes for children. The book is sold to schools and libraries. Include in your reply, the source of your information. Thanks!

Here's a whole page of surface temperature data from NOAA for all of the Great Lakes.

The Great Lakes WATER Institute might be able to help you.

Response by poster: I've already checked NOAA. Its charts and graphs have tons of raw data that I don't have time to "crunch." I need four specific average annual water temperatures--one each for Lake Michigan, Huron, Erie, and Ontario. I have the temp for Lake Superior--40 degrees F.
