Watershed Hydrology

The Lower Tallapoosa Watershed (HUC 03150110) covers approximately 3,617 square miles in Alabama and Georgia. It is characterized by a humid subtropical climate with hot summers and mild winters. Precipitation occurs year-round, with the wettest months being January and February. The Tallapoosa River and its tributaries are the main hydrological features of the watershed. The snowpack in the area is generally minimal due to the mild winter temperatures. Surface water quality is impacted by agricultural and urban runoff, as well as industrial discharge. The main reservoirs in the watershed are Yates Lake and Lake Martin, which provide hydroelectric power, recreation, and water storage for municipal and industrial uses. Interesting climatic facts include occasional winter tornadoes and the potential for tropical storms and hurricanes in the summer and fall. Trends in the area include increased urbanization and land use change, which can impact water quality and quantity.
