The U.S. Army Corps of Engineers is issuing a small craft advisory for the McClellan-Kerr Arkansas River Navigation System in Arkansas. Heavy rainfall in eastern Oklahoma last week has resulted in Arkansas River flows exceeding 70,000 cubic feet per second at Trimble Lock and Dam.

Small craft advisories are issued when flows exceed 70,000 c.f.s. Strong currents and large debris can threaten the safety of pleasure craft during high flows.

A crest near 95,000 c.f.s. will make its way downstream over the next few days.
