Watershed Hydrology

The Middle Alabama Watershed (HUC 03150203) covers an area of approximately 7,000 square miles in central Alabama. The hydrology of the watershed is characterized by the presence of several rivers, including the Coosa, Tallapoosa, and Cahaba, which provide surface water for the area. The watershed is also home to several reservoirs, including Lake Martin and Lake Harris, which are used for recreation and as a source of drinking water. The watershed experiences a humid subtropical climate, with hot summers and mild winters. It receives an average of 54 inches of precipitation per year, with most of the rainfall occurring in the summer months. The area also experiences occasional droughts, which can impact streamflow and water availability. Snowfall is rare in the Middle Alabama Watershed, with only occasional light snowfall occurring during the winter months. The area is not typically impacted by significant snowpack. Water quality in the watershed is generally good, although there are some concerns about nutrient runoff from agricultural operations and urban development. The Alabama Department of Environmental Management monitors water quality in the area and works to address potential issues.
