Event narrative (NOAA)
Widespread rainfall amounts of 3-6+ inches, with isolated amounts up to 10 inches, fell across Central and Southern McCurtain County Oklahoma on June 7th-8th, resulting in widespread flooding across these areas. This did result in considerable rises along the Little River some 40-50 river miles downstream at Horatio, AR (Sevier County), which crested at 30.89 feet on June 10th, 2021. This was just above the 30ft major flood stage, although impacts were mainly confined to considerable lowland flooding of several hundred acres of grazing and farmland, along with significant backwater flooding along the Cossatot River with its confluence with the Little River north of Wilton. This high water routed downstream along the Little River south of Horatio to just northwest of the Winthrop community
