Since the initial tailings breach of August 4 Mount Polley Mining Corporation (MPMC) has been working to reduce the flow of turbid (cloudy) water into Quesnel Lake.
They have been doing this through efforts to control the sources of turbid water or erodible materials. Erodible materials are soils or tailings that have been left exposed and, if rain falls on them, could lead to erosion and then generation of more cloudy water.
A specialty equipped helicopter was brought to the site on September 12 to help with the task of seeding exposed areas. Nine hundred 25kg bags of fast-germinating grasses, which were applied to exposed areas in an effort to provide vegetative cover.
