Water is an extremely important part of Randolph County's geography, history, economy, and culture. The many rivers, streams, and ditches crossing the county have featured prominently since prehistoric times, and many of the hundreds of archaeological sites are along waterways. Tribes of [[Lenape]], [[Shawnee]], and [[Cherokee]] were settled in the area along rivers but left the area following the [[1811–12 New Madrid earthquakes]].<ref name="eoc" />

Randolph County is home to five major rivers: Black River, [[Current River (Ozarks)|Current River]], [[Eleven Point River]], [[Fourche River]], and [[Spring River (Arkansas)|Spring River]].

Running from east to west toward its own mouth in the southern tip of Randolph County, the Black receives the Current River and Fourche River east of Pocahontas. The Current River serves as the northeastern county boundary with Clay County before turning southwest, passing Reyno and Biggers and meeting the Black east of Pocahontas. The Fourche River enters Randolph County near [[Doniphan, Missouri]] and runs south to meet the Black east of Pocahontas. The Black meets the Spring at the southern tip of Randolph County near [[Black Rock, Arkansas|Black Rock]].

The Spring River serves as the county's southwestern boundary with Lawrence County between Davidsonville Historic State Park and [[Ravenden, Arkansas|Ravenden]]. The Eleven Point River enters from [[Missouri]] near [[Billmore, Missouri|Billmore]] and runs south to empty into the Spring just west of the state park.

Rivers brought early prosperity to the county during white settlement for navigation. Control of the rivers and [[Pitman's Ferry]] led to military action in the county during the [[American Civil War|Civil War]], including a skirmish in 1862. Following the war, natural [[mineral spring]]s purported to have healing properties attracted visitors to [[Warm Springs, Arkansas|Warm Springs]] and Ravenden Springs.
