A waterfall that drops over a stone wall directly into Pickwick Lake just north of J.P. Coleman State Park near Iuka. It is accessible only by boat. Height is reported as 40 ft by the World Waterfall Database, with some sources citing 50 ft.

Its 40 ft drop is taller than about 33% of the 775 waterfalls we track.

Cooper Falls sits on Cooper Creek (into Pickwick Lake). It lies in Tishomingo, Mississippi. The site is on public land managed by Tennessee Valley Authority / Mississippi Department of Wildlife, Fisheries, and Parks (near J.P. Coleman State Park).

This is a backcountry waterfall: a remote, long, or permit-required trek for prepared visitors. This one is deep enough in that you should plan for a full backcountry trip — map, water, and a margin of daylight. The nearest town is Iuka.

When to go: Winter and spring. Flow usually peaks after snowmelt and heavy rain and tapers through late summer — a quick look at recent streamflow and the managing agency's conditions page can save a wasted trip.
