The barges went under the Highway 62 bridge and were headed towards the Webbers Falls Lock and Dam 16 earlier in the evening. News 9 confirmed that Life Flight is flying overhead, trying to locate the barges, so first-responders will know where they are and see their path.

The City of Webbers Falls believes that if the barges impact the dam, it would be catastrophic. However, the lockmaster in charge of Lock and Dam 16 believes the worst-case scenario would be to break a couple of the gates.

Muskogee's police chief said that if it misses the Lock & Dam 16, the next thing the barges will hit will be the Interstate 40 bridge. The Oklahoma Highway Patrols is on standby to block traffic there should that happen.
