Important Notice: This website was created by the Sanford Lake Improvement Board to provide information regarding various management activities on the lake. With the failure of the Sanford Lake dam in May of 2020, the lake was lost. Since that time, the Sanford Lake Improvement Board has become temporarily inactive. However, this website is being maintained for informational purposes. To find out more about the status of the lake, visit the Four Lakes Task Force website.
