Nechako Reservoir Update - March 11, 2021

Reporting Period: March 5 to March 11, 2021

  • Reservoir level has decreased in the past 7 days from 2795.83 feet to 2795.50 feet.
  • Skins Lake Spillway discharge is unchanged at 82 m3/s in the past 7 days.
  • Skins Lake Spillway discharge will likely be increased by 15 m3/s early next week, which may result in an increase in water levels in the Nechako River of approximately 0.10 metres. The increase in water level may cause water to flow on top of the ice, which may lead to unstable ice cover.
  • Nine (9) mm of precipitation was observed last week and four (4) mm of precipitation is expected for next week.
  • Based on current conditions, there is a 90% chance that the Nechako Reservoir will not fill completely in 2021. Please refer to the illustration below regarding reservoir conditions.
  • Ice cover on the Nechako River prevents accurate measurement of discharge. Discharge will be reported again in the Spring.
  • Ice jams sometimes form during freeze up. Be cautious around the river, and particularly in low lying areas. If you notice an ice jam form, please notify Rio Tinto immediately by emailing NechakoReservoirUpdates@riotinto.com.
