For more information, there is a well-designed website about Lake Winnipesaukee.
www.winnipesaukee.com
The site also lists the lake's current water temperature (as measured off Jolly Island).

The
Bear Island Webcam
page also gives current air and water temperatures. (Of course, Bear
Island is closer to Three Mile than Jolly Island is.)
