Arkabutla Lake releases reshape river access, increase flood risk near Marks

The U.S. Army Corps of Engineers, Vicksburg District, operates Arkabutla Lake in a way that changes reservoir pool levels and downstream river stages on the Coldwater River. Those operational changes can occur quickly and with limited local notice, and they have immediate consequences for boaters, anglers, property owners, and Quitman County public officials. Boat ramps and launch areas near Marks may be temporarily unusable when releases are underway, shorelines can become unsafe, and access roads can be affected by both high and low flows.

The Corps maintains live monitoring of reservoir pool levels and downstream river stages on its Arkabutla project pages, including notices of planned releases and safety guidance. Local officials in Quitman County, including emergency management and public works, generally coordinate their advisories with Corps releases to reduce public risk. For recreation users that means confirming ramp and launch availability on the Corps Arkabutla project page before departing, and planning for limited nearby services such as fuel and tackle within the county.

Operational variability also has broader community implications. Emergency planning and response resources must be prepared for rapid water level changes that can create temporary flooding or isolate low lying properties. Property risk assessments and insurance considerations for homeowners along the Coldwater River and Arkabutla shoreline are affected by how often and how quickly pool levels change. Local public facilities and parks can require short term closures to protect visitors and reduce liability when releases are announced.

For immediate information, use the Corps Arkabutla project page for live pool and river stage data and planned release notices. If you observe rapidly rising water or a property threat, contact Quitman County emergency management so officials can respond and coordinate with Corps operations. Checking official Corps advisories before you go is the simplest step residents can take to protect safety and reduce disruption to local recreation and businesses.
