The topography of Oklahoma City is predominantly characterized by flat terrain and gently rolling hills. The elevation averages around 1,200 feet above sea level, with no significant mountains or deep valleys within the city limits.
Water features define much of the local topography. The city is punctuated by three primary reservoirs: Lake Hefner to the northwest, Lake Overholser to the west, and Lake Stanley Draper to the southeast. The Oklahoma River runs east-west just south of the downtown core. The landscape's relatively flat nature historically made it ideal for both cattle ranching and rapid urban expansion.
