The Lower Yadkin Watershed (HUC 03040103) covers approximately 1,790 square miles in North Carolina, with the Yadkin River serving as the main hydrologic feature. The watershed is characterized by a humid subtropical climate, with an average annual rainfall of 45 inches and an average annual temperature of 60°F. Snowfall is rare, with an average of only 2 inches per year. The Yadkin River is a major source of surface water for the region, serving as a drinking water source for several cities and towns. The river is also home to several large reservoirs, including High Rock Lake and Tuckertown Reservoir, which provide important recreational opportunities for the area. Water quality in the watershed is affected by agricultural and urban runoff, as well as industrial discharges. The reservoirs in the region have been found to contain elevated levels of nutrients, such as nitrogen and phosphorus, which can lead to harmful algal blooms. Climate change may have an impact on the Lower Yadkin Watershed in the future, with potential changes including increased temperatures, more frequent extreme weather events, and changes in precipitation patterns.
