Additional information regarding current conditions

Overall, since 1 April 2022, we are experiencing the 3rd highest amount of rain on record for this period due to the late Spring and recent rain events (see chart below).

The Nechako Reservoir is approaching its maximum operating level of 2,800 feet, with projections indicating it will peak slightly below 2,800 feet over the coming days. As of 7 July 2022, the risk of flooding is considered moderate at Vanderhoof, with low lying areas potentially seeing some high water in the Cheslatta watershed and upper Nechako River. The BC River Forecast Centre remains best positioned to evaluate flood risk and we are working very closely with them to exchange information and make decisions about reservoir management to prevent exceeding the flood threshold.

Rio Tinto continues to work closely with Indigenous and local communities, stakeholders, as well as the Water Control Board  to uphold reservoir safety and minimize downstream impacts. We will continue to issue information through Flow Facts, Facebook and the Get Involved Nechako website. Real-time reservoir activity can be viewed at any time here.

Skins Lake Spillway discharge to be maintained
Skins Lake Spillway discharge is currently at ~370 m3/s and is expected to be maintained at this level for at least a week, to reduce the risk of reaching full reservoir levels, while also minimizing potential effects on downstream communities. 

Further updates will be provided outside of regularly scheduled Flow Facts as needed.
