Data from a recent survey conducted by the Adirondack Lake Survey Corporation were used to evaluate the influence of lake surface area on the acid-base status of lakes in Adirondack State Park, New York. Acid neutralizing capacity (ANC) in the small lakes (<4 ha) occurred more frequently at extreme values (>200, <0 microeq/L), whereas larger lakes tended to be intermediate in ANC. Consequently, acidic (ANC = or < 0) and low pH lakes were typically small. The small lakes also exhibited lower Ca(2+) concentration and higher dissolved organic carbon than did larger lakes. Lakes = or > 4 ha were only half as likely to be acidic as were lakes = or > 1 ha in area. These data illustrate the dependence of lake chemistry on lake surface area and the importance of the lower lake area limit for a statistical survey of lakewater chemistry.
