At over a million years old, Mono Lake is one of the oldest lakes in North America and has an average depth of 100ft. Mono Lake is known as the Dead Sea of California. It’s 2.5 times saltier than the ocean and high in alkalinity.
Mono Lake is also a good example of the power of people coming together for a good cause: to protect Mother Nature and unique ecosystems like this. Mono Lake’s surface level once stood at an elevation of 6,417 feet in 1941.
It was during this year that the Los Angeles Department of Water built a reservoir in the Mono Basin. This aqueduct providing LA with water drained Mono Lake’s main tributaries raising the salinity level of the lake and taking away its freshwater supplies.
The dropping levels caused a land bridge to form between the shore and Negit Island, home of thousands of nesting migratory birds. This land bridge gave predators a way to kill huge portions of the bird population causing an ecological crisis.
