Constraining the Physical Processes that Govern Oxygen Distribution in Lake Zug
Topographic constraints, such as sills or constrictions, play a critical role in regulating water exchange between different basins, often creating complex circulation patterns that influence the transport and distribution of sediments, nutrients, and oxygen. This study examines the inter-basin exchange in Lake Zug, where two basins, a shallow northern basin (100 m deep) and a deeper southern basin (180 m deep), are connected by a lateral constriction. Lake Zug is meromictic, remaining stratified throughout the year, with anoxic conditions prevailing below approximately 120 m. Consequently, the shallow northern basin remains well-oxygenated, while the bottom 60 m of the southern basin is characterised by anoxic water. Historical fine-scale measurements have revealed the presence of oxygen intrusions at depth, suggesting episodic oxygen supply to the anoxic zones of the southern basin.
