The primary constituents of the creek's flow are precipitation and groundwater. The creek is fed by several tributaries, including the Little Antietam Creek and the West Branch. There are no major dams along its course. Seasonally, the creek experiences high flows during the spring and fall months due to increased precipitation, while low flows occur during the summer months. Interestingly, during the Civil War, the Battle of Antietam took place along the creek, making it the site of the bloodiest single day in American history.
