Pienitz, R., Smol, J.P. and Lean, D.R.S. 1997. Physical and chemical limnology of 24 lakes located between Yellowknife and Contwoyto Lake, Northwest Territories (Canada). Canadian Journal of Fisheries and Aquatic Sciences 54: 347-358.
- Data on the water chemistry and limnology of 24 lakes located between Yellowknife (628279N, 1148219W) and Contwoyto Lake (658309N, 1108009W) in the central Northwest Territories were examined using principal components analysis and other statistical techniques. The study sites were mostly shallow (Zmax = 2.5–25 m; mean = 8.2 m), nutrient-poor (3.4–12.7 mg total phosphorus/L; mean = 6.6 mg × L–1), low-alkalinity lakes. Water was typically low in solutes (specific conductance near 0–100 mS × cm–1), with slightly acidic to alkaline pH (6.2–8.9). Levels of all nutrients and major ions showed identical trends of decreasing concentrations with increasing latitude, with the highest concentrations generally in lakes with conifer-forested catchments in the south.
