As Wisconsin’s climate changes over the coming decades, the hydrology of its landscapes will almost certainly change along with it. In turn, changes will occur in stream flows, lake levels, and wetland extent and in the ecosystems that depend on them. Many questions abound: Will present day trout streams remain as trout streams? Will lake levels rise or fall? The WICCI Central Sands Hydrology and Aquatic Ecology workgroup aims to frame potential aquatic resource issues and explore their dependencies on a changing climate.
