Freshwater  Refers to water from rivers, lakes, reservoirs, underground streams, and other sources. Water is continually lifted from the oceans by evaporation and then returned to the land as ice, snow, or rain. Ice and snow melt from mountains to release freshwater to our rivers, streams, lakes, and to resupply underground streams. -  From Exploring Estuaries Glossary
