The river experiences seasonal flow changes due to rainfall and snowmelt. The flow tends to peak in May and June and is at its lowest in December and January. The river is not impounded by any dams. Interestingly, the Cannonball River gained widespread attention in 2016 when it became the site of protests against the construction of the Dakota Access Pipeline, which was feared to harm the river and its tributaries.
