The average water temperatures of Dale Hollow Lake ranges from 45-80 degrees, and the deepest area of the lake is in the main channel near the dam, totaling 130 feet. Dale Hollow Lake is one of the few lakes in Tennessee, and our nation, that provides an unobstructed view of nature and natural beauty at its best due to the restrictions of private boat docks and the removal of trees from the shorelines.
The quality of the water in Dale Hollow Lake is important for the Dale Hollow National Fish Hatchery, located below the dam. The hatchery is the largest federal trout hatchery east of the Mississippi River, producing 1.5 million trout per year, totaling 300,000 pounds. Dale Hollow Lake is a popular wintering area for the bald eagle, our American symbol. These beautiful birds can generally be observed from mid-December to mid-February.
