On May 23, 2019, two loaded barges, the MTC 7256 and LTD 11140, struck the Webbers Falls Dam. The barges had broken away the previous day from a fleeting area on the Grand River in Muskogee, Oklahoma, during historic flood waters and high river current. The two barges were total constructive losses. No pollution was reported. Total damages exceeded $4.7 million, including the amount spent to remove the barges and repair the dam ($3,956,249).

The ​​​probable cause of the barge breakaway and contact with the Webbers Falls Dam was the force of the river current acting on the moored vessels at the Grand River fleeting area, which exceeded the capacity of the mooring wires, due to the extreme rise and flow of water in the Grand River as the Fort Gibson dam released major amounts of water in a short period of time.
