Conclusions: Elevation, slope and the percentages of bogs and fens in a landscape influence the degree to which mid-boreal lakes are sensitive to acidic deposition orignating from nearby mining operations. Thresholds/Learnings: Synopsis: This study evaluates the acid sensitivity of lakes in Saskatchewan within ~300km of Fort McMurray. The study area is downwind of atmospheric emissions sources from regional oil sands mining operations and there is concern that the lakes may be threatened by acidification. A helicopter sampling program was implemented in late September 2007 and 2008 to measure 16 chemical variables (e.g., Ca, Mg, Na, pH) and 15 environmental variables (e.g., latitude, elevation, slope, percent bog,...
