The Leviathan Mine Pit Flow is located near Markleeville, California, and is a result of decades of mining activities in the area. The hydrology of the site is influenced by the nearby Sierra Nevada mountain range, which provides snowmelt and rainwater runoff that feeds into the pit. The pit is also known to contain high levels of heavy metals, which can have negative impacts on water quality and aquatic life. To mitigate these impacts, a water treatment plant has been installed to remove contaminants before discharging the water into nearby streams. The site has limited agricultural or recreational uses due to its history and ongoing remediation efforts.
