Dardanelle Lock (No. 10) NM 205.5 is currently closed to traffic due to dangerous cross currents downstream of the dam. The spillway release configuration is currently restricted due to mechanical issues resulting in concentrated flows that present a danger to traffic in the downstream approach. Crews are onsite and an additional notice will be submitted when the issue is resolved.
