There has been a landslide on the north side of the lower Churchill River.
Nalcor says it happened about 750m downstream of Muskrat Falls. The company says there is no cause for concern, no risk to the public and no impact on the facility.
It indicates that landslides along the banks of the Churchill River are natural occurrences, which can be expected from time to time, as have happened in the past.
Nalcor issued the notification on Thursday afternoon.
