The Upper Tar watershed (HUC 03020101) covers an area of approximately 1,450 square kilometers in North Carolina. The region is characterized by a humid subtropical climate with hot summers and mild winters. The hydrology of the area is dominated by the Tar River, which flows from the headwaters in the Piedmont region to the Pamlico Sound. The watershed is known for its significant snowpack during the winter months, which contributes to the surface water supply in the Tar River. The surface water quality in the region is impacted by the presence of nutrients, sediment, and bacteria. There are several reservoirs in the watershed, including Falls Lake and Kerr Lake, which serve as sources of drinking water and recreational activities. Interesting climatic trends include an increase in average temperatures and a decrease in precipitation in recent years.
