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. However, with recent low precipitation forecasted, Nechako River levels are expected to continue to decrease.

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, as well as community meetings as needed. Real-time reservoir activity can be viewed at any time here.
