DNR Hydrography - Groundwater Dominated Lakes

This feature class represents lakes that may be more influenced by groundwater flow than surface-water flow. The lakes were selected based solely on watershed area to lake area ratio. This ratio is a major factor in determining if lakes are dominated by groundwater flow or surface water flow. Other factors, such as local geology and groundwater gradient are important. But they are often not as well quantified as the watershed to lake area ratio.
