RedactedNarrative: On 28 June 2018 around 2 PM two kayakers were traveling south on the Great Miami River. As the two approached the low head dam they paddled over to the eastern bank shoreline and tied off to one another. Operator of vessel # 1 had their oar n the water, dug into the river bottom holding the kayaks in place. The oar lost contact with the river bottom and the two kayaks began drifting down stream towards the low bead dam. The kayaks continued over the low bead dam, causing operator of vessel# 2 to be ejected. Operator of vessel# 1 continued over low head dam as the kayak sank once going over the dam. Operator of vessel# 1 exited the kayak once the kayak began to sink. Operators of both kayaks swam to shore (life jackets on). No injuries
