Abstract

Maximum values of acid neutralizing capacity (ANC) in lake outlets generally occur during summer and autumn. During spring snowmelt, transport of acidic water through acid-sensitive watersheds causes depression of upper lake water ANC. In Adirondack lakes, SO42- concentrations were diluted during snowmelt and did not depress ANC. For lakes with high baseline ANC values, springtime ANC depressions were primarily accompanied by basic cation dilution. For lakes with low baseline ANC, NO-3 increases dominated ANC depressions. Lakes with intermediate baseline ANC were affected by both processes and exhibited ANC depressions. Lakes with intermediate baseline ANC were affected by both processes and exhibited larger ANC depressions. -from Authors
