It is a popular destination for tubing, swimming, and kayaking, and is known for its crystal-clear water and picturesque surroundings. Historically, the river was used by Native Americans for fishing and hunting, and later by German settlers for agriculture and transportation. The river is fed by natural springs and is protected by various environmental conservation programs. There are two dams on the Comal River, including the Comal Springs Dam and the Lake Dunlap Dam. These dams were constructed for flood control and to create reservoirs for water storage. The river is also used for irrigation purposes for nearby farmland.
