    Acid neutralizing capacity of lakes in the North Cascades area of Washington State (1986)
    Springer
    Water, air & soil pollution 30 (1986), S. 1045-1053

    Notes: Abstract Thirty three lakes were surveyed in 1983 in the North Cascades area of Washington State and 27 additional lakes were surveyed in 1984 to characterize lake chemistry in the area. Lakewater ANC was less than 100 ueq 1−1 for 37% of the lakes and less than 200 ueq 1−1 for 68% of the lakes. The North Cascades are very similar to unimpacted sensitive areas of North America and Northern Europe in mean alkalinity and (Ca + Mg). Bedrock geology appears to have a significant influence on surface water ANC with lakes on granitic and metamorphic bedrocks having the lowest ANC.

    Temporal variability of lake waters in the North Cascades mountains (Washington, U.S.A.) (1986)

    Notes: Abstract Five lakes in the North Cascades were sampled at regular time and depth intervals during the open water period in 1984. Surface water ANC was depressed during snowmelt and then increased as summer and fall progressed. Shallow lakes circulated completely in the fall, whereas deep lakes ( 〉 75 m) did not. Sulfate and N03 concentrations in the lakes increased during the snowmelt period and then decreased until iceover. No significant differences were found between surface ANC measurements during fall circulation in successive years.
