The Upper Ocmulgee Watershed (HUC 03070103) covers approximately 3,662 square miles in Georgia, USA. The area is characterized by a humid subtropical climate with hot summers and mild winters. The watershed is primarily fed by surface water with the Ocmulgee River being the main source. The river provides a variety of recreational activities such as fishing and boating. The Upper Ocmulgee Watershed also contains several reservoirs, including Lake Jackson, which serves as a drinking water source for the city of Atlanta. The area is prone to flash floods, particularly during the summer months. Snowfall is relatively rare in the watershed, with an average of only one inch per year. There have been concerns regarding water quality due to high levels of sediment and nutrients, which can lead to harmful algal blooms. Conservation efforts have been implemented to address these issues.
