BC Hydro is performing its annual maintenance to the John Hart Generating Station. The maintenance work this year will require a redistribution of flow between Elk Falls Canyon and the generating station on May 26 and May 30. On these days, three of the six generating units will need to will be shut down and additional water will be released through the spillway gates and down Elk Falls Canyon to maintain the current Campbell River flow of approximately 82 cubic metres per second (m3/s).
 
On May 26 and 30, in the early morning hours, BC Hydro will reduce power generation and increase flow in the canyon. The canyon flow will increase from about 4 m/3s to about 24 m3/s. At around 5:00 pm after one of the units is returned to service, the canyon flow will be slowly reduced while the discharge from the generating station is increased by the same amount. The river flow below the generating station will remain unchanged.
 
The public is advised to stay away from the river above Elk Falls on these two days. Safety signage will be in place. And from the safety of the Elk Falls lookout, there will be good vantages of the five-fold increase of water flow passing over the falls.
