He named the lake his original cabin was constructed on Eagle Lake because of a nesting in a nearby pine tree. About the same time (1882), Louisa McLeod purchased 115 acres in the area to the east. As the land was sold, the city began to take shape and was laid out around 1887.Earlier on, Eagle Lake was known for its local businesses. These included a brickyard, a turpentine mill, and two citrus packing houses that were both lost in the 1940s. During the mid-50's and into the 60's, the city was host to a wooden bathing house with dressing rooms, long wooden covered dock, dance hall, picnic facilities, and a diving platform at the Crystal Beach Pavilion on the SW side of Eagle Lake. During the 1980s, the city adopted the motto "Growing with people in mind". It continues to be the tenet of the city today.
