The river's flow providers include tributaries, such as the Missouri River, and rainfall. The Thebes gauge is also affected by dams upstream, including the Lock and Dam 26 at Alton, IL. Seasonal trends influence the river's flow, with spring and summer typically bringing higher water levels and faster currents due to increased precipitation and snowmelt. However, the river's flow can also be affected by droughts and human interventions, such as channel dredging. Interestingly, the Thebes gauge is located near the site of the devastating 2011 flood, which breached nearby levees and caused extensive damage to the surrounding area.
