Lakes and Ponds
Glaciers carved most of the lakes in the park thousands of years ago. As the glaciers moved they gouged out the valley floor. When the glaciers melted they left behind a depression in the ground that filled with water from melting glacial ice. These depressions became the lakes that we see today. Jackson Lake, the park's largest lake, is a natural lake raised by a 39-foot tall man-made dam.
Ponds and lakes provide a variety of habitat in and around them. From cutthroat trout to crawfish, from great blue herons to moose, almost all wildlife in the park derive some benefit from lakes and ponds. Ponds and lakes also provide recreational opportunities for visitors. Some of the easiest and most popular hikes are around small lakes and ponds. All of the lakes are open to swimming and non-motorized boating. Jackson Lake also allows motorized boats for recreational use.
