Lake monitoring and research

Studying lakes provides an improved understanding of lake ecosystem dynamics and valuable information that helps lead to sound lake-management policies. The USGS collects hydrologic data in lake settings, studies water and nutrient budget development, conducts source-loading analysis, explores groundwater interactions, and performs lake water-quality modeling.

Little St. Germain Lake: Phosphorus loading, winter anoxia, and stage regulation

Little St. Germain Lake, Wis., consists of four main basins separated by narrows. This study monitored lake water quality, identified phosphorus sources, determined spatial and temporal distribution of oxygen, evaluated the effectiveness of winter aeration systems, and modeled groundwater/lake-water interactions.
