A male neighbor and another man both tried to rescue her, Troyer said. Swiftwater rescue crews responded.
Further details were not immediately available.
The person was with two other inner-tubers before the incident.
Multiple agencies responded about 3 p.m. north of Orting, and used a chainsaw to get the trapped person out.
Orting Valley Fire and Rescue said it could not provide further information, due to privacy laws.
