The Hauns lived in Kemano, 1955-1969. In 1961, a major rock fall occurred in the tunnel delivering water to the turbines in the Kemano Powerhouse. Inspection and repair were needed. J.T. (Dale) Madill, Manager of BC Power Operations, inspected Penstock 2 together in a rubber raft, June 1961. The raft was recommended by Alcan head office, Montreal as the safest method to ride down with the water. To communicate, a hammer would be used on the penstock, a series of blows signaling stop, open the valve, and danger. The latter would not be needed "as there will be no danger". The raft had got hung up in the flat portion and had to be pushed along to the next incline. This plaque commemorates this event.
