The report, authored by five researchers at the University of Northern British Columbia, documented the findings of samples taken in the two months immediately following the spill, between Aug 4 and Oct 4, 2014.
It found the levels of the lake rose 7.7 centimetres in that time, and the temperature at the bottom of the lake increased from 1 to 2.5 degrees Celsius.
It also found higher levels of sediment — associated with an increase in turbidity in the lake.
"That plume that we observed is distributing throughout the lake as a result of the natural swinging or rocking of the lake," Nikolaus Gantner, one of the report's authors, told Daybreak North's Russel Bowers.
While the report provides the hard data, it doesn't have answers about what the impact of that sediment will be on fish.
"It does provide a bit of context in terms of what happened from our perspective, but in terms of the final answers as to whether I'm going to be able to eat my fish — these are long term questions that aren't immediately answerable at this point," another co-author Sam Albers, who is the manager of Quesnel River Research Centre in Likely, B.C., told Daybreak Kamloops' Shelley Joyce.
"It's going to be the first in a long series of research papers."
