Chemical and biotic characteristics of two low-alkalinity lakes in northern Wisconsin

Webster, K. E., Eilers, J. M., Wiener, J. G., Glass, G. E. and Garrison, P. J., 1993, Chemical and biotic characteristics of two low-alkalinity lakes in northern Wisconsin: relation to atmospheric deposition: Madison, Wisconsin, Department of Natural Resources, 77 p.


Synoptic surveys of water chemistry in north-central Wisconsin documented the presence of many low alkalinity lakes potentially sensitive to acid deposition. Furthermore, lake hydrologic type proved to be a key factor in determining lake sensitivity: the low alkalinity systems were predominately seepage lakes. To test this hypothesis and identify the controls on the chemistry of these low alkalinity systems, the authors initiated hydrologic, chemical, biological and limnological studies at Lakes Clara and Vandercook in 1980. The report summarizes the results of those studies (including previously published hydrologic results) conducted between 1981 and 1983. The major goals are to assess the sensitivity of the study lakes to acid deposition and to identify key processes controlling the acid-base chemistry of these software seepage lakes.
