A lake can be either. Most lakes are freshwater, but some are brackish or saline.
- Freshwater lakes have low salt concentrations and are the main sources of drinking water and freshwater ecosystems (examples: the North American Great Lakes such as Lake Superior).
- Saline (salt) lakes occur where evaporation concentrates salts, usually in closed basins with little or no outflow (examples: the Great Salt Lake, the Dead Sea, the Caspian Sea is technically a large saline lake).
- Brackish lakes fall between freshwater and seawater in salinity (common in some coastal lagoons or estuaries).
Whether a specific lake is fresh or salty depends on its water balance (inflow vs. outflow and evaporation) and the geology of its basin. Would you like help checking the type of a particular lake?
