Officials with the Yukon government say dozens of dead fish found earlier this week in a creek near Victoria Gold's Eagle mine were likely killed by a discharge of contaminated water from the mine site.

Litter along the stretch of the Glenn Highway from Eagle River to Wasilla is significantly less noticeable.

State nuclear agency Rosatom, whose subsidiary operates the mines at the Dobrovolnoye uranium deposit, denied that its mining facilities were impacted by the flood.
