BC Hydro Issues Public Safety Advisory of Higher River Flows

November 25, 2014

From BC Hydro:

"The wet weather over the next few days will be increasing the Comox Lake Reservoir level. The weather forecast, with uncertainties, shows a gradual increase in rain to peak at just over 50 mm on Thursday. BC Hydro is uncomfortable with the reservoir above 134 m for flood risk management considerations and future storm systems. The reservoir is currently at 133.7 metres and rising. Water freespills over the dam at about 135.3 metres.

Beginning tonight, BC Hydro will increase the discharge from Comox Dam from about 40 m3/s to about 75 m3/s. The discharge will be kept at that rate through Friday under the current forecast but may increase if inflows are more than forecasted. Water inflows into the reservoir are expected to peak on Thursday at around 115 m3/s.

Through Friday, BC Hydro advises the public to stay out of the Puntledge River due to the high river flows. Warning signage is being posted today along the river.

BC Hydro will keeping a close eye on the high ocean tides, and the highest tides this season at 5.1 metres, on Thursday morning when the Browns and Tsolum rivers may be peaking. The storm should not provide any storm surges given the winds are coming out of the west.  BC Hydro will reduce discharges from the dam as needed just prior to the high tides.

The good news is a high pressure should begin to form on Friday and lead to dry conditions into early next week."
