Variations in lake evaporation have a significant impact on the energy and water budgets of lakes. Understanding these variations and the role of climate is important for water resource management as well as predicting future changes in lake hydrolog

A detailed mineral-solute mass-balance spreadsheet model has been developed to improve understanding of mineralogic controls on water composition in surface waters and groundwater systems dominated by silicate lithologies. The spreadsheet-based appro

Dispersion of solutes in groundwater is caused mainly by spatial variation in aquifer properties (i.e., heterogeneity) but additional dispersion can be induced by temporal fluctuations in the flow field. We studied dispersion of an oxygen isotope plu

SUMMARY 1. Within a lake district of relatively homogeneous geomorphology, the responses of lakes to climate are influenced by the complexity of the hydrogeologic setting, position in the landscape, and lake-specific biological and physical features.

Multiple calibration targets were used to calibrate a two-dimensional finite-difference model of a ground water lake system. The calibration targets included (1) steady-state head data, (2) transient head data, (3) head gradients, and (4) flowpath in

The region studied includes the Laurentian Great Lakes and a diversity of smaller glacial lakes, streams and wetlands south of permanent permafrost and towards the southern extent of Wisconsin glaciation. We emphasize lakes and quantitative implicati

Climatic shifts to drier conditions during drought alter the hydrologic pathways of water and solute flow to aquatic ecosystems. We examined differences in drought-induced trends in the semiconservative cations, Ca+Mg, in seven northern Wisconsin lak

The isotopic composition of precipitation and river runoff in the vicinity of the North American Great Lakes is characterized by a higher deuterium-excess value than observed in the advecting air masses. It is suggested that this indicates that evapo
