Upper Catawba

Watershed Hydrology

The Upper Catawba Watershed (HUC 03050101) covers an area of approximately 1,009 square miles in western North Carolina. The Catawba River is the main hydrological feature in the watershed and provides drinking water to over 2 million people. The area experiences a humid subtropical climate with mild winters and hot summers. Snowfall is common in the winter, with an average of 20-30 inches annually. Surface water quality in the Catawba River is monitored closely due to high concentrations of pollutants from agricultural and urban runoff. There are four large reservoirs within the watershed, including Lake James and Lake Norman. These reservoirs are important sources of drinking water and recreation for local communities. In recent years, the region has experienced more frequent and severe droughts, which have impacted water availability and quality. Efforts are underway to improve water management practices and protect the watershed's natural resources.
