The Watauga Watershed (HUC 06010103) covers an area of approximately 1,201 square miles in northeast Tennessee and western North Carolina. The hydrology of the watershed is dominated by the Watauga River, which originates in the Appalachian Mountains and flows into Cherokee Lake in Tennessee. The watershed receives an average of 50 inches of precipitation annually, with the majority falling as rain during the summer months. Snow accumulation is common in the higher elevations during the winter months and can contribute to the surface water supply in the spring and summer. The Watauga Reservoir, located in the southern portion of the watershed, provides drinking water and hydroelectric power to the surrounding area. The reservoir is also a popular destination for fishing and boating. Interesting climatic facts include the occasional occurrence of severe winter storms and flooding events in the summer months. Trends in the watershed include increasing temperatures and changes in precipitation patterns due to climate change.
