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,...

Conclusions: Watershed area and the percentage of a watershed that is covered by forest significantly influence watershed sensitivity to acidic deposition. Based on these landscape pattern indicators, one can identify subregions where acid-sensitive streams are most abundant. Thresholds/Learnings: Synopsis: Hypotheses relating to watershed sensitivity to acidic deposition were tested using a geologic classification scheme and available regional data for the Southern Appalachian Mountains region. Landscape characteristics including lithology, elevation, elevational gradients, landscape position, and forest cover were used in the geologic classification scheme. Acid neutralizing capacity (ANC) was used as the stratifying...
