1908-1913 DWP constructs Los Angeles Aqueduct
  A project first proposed in 1905 by Fred Eaton. For under $23 million, L.A. constructs the aqueduct to the Owens Valley. Finished in 1913, DWP begins diversions from the Owens River into the newly completed Los Angeles Aqueduct. Owens Lake dries up by 1926. 

 

1912 L.A. begins acquiring land and water rights in the Mono Basin
 

Planning for the possibility of an extension of the aqueduct to the Mono Basin, L.A. begins acquiring land and water rights.

 

1920 Mono Basin public land withdrawn
 

Reclamation Service head Arthur Davis withdraws Mono Basin public land from private settlement or claims.

 

1923 Los Angeles applies for Mono Basin water rights
 

Los Angeles applies to the State Water Commission to appropriate the entire flow of the Mono Basin streams for domestic use and power generation.

 

1930 Los Angeles passes bond for Mono Basin extension
 

L.A. voters pass a second $38.8 million bond by a margin of 8 to 1 after an initial one failed. This bond is to fund the Mono Basin extension of the L.A. Aqueduct.

 

1930-1935 DWP condemns littoral rights of Mono Basin property owners
  In 1930 DWP begins condemnation procedures against 78 defendants for land, littoral, and riparian rights in the Mono Basin.

Some landowners go to court to contest the awards given in condemnation proceedings. This becomes known as the Aitken Case. Under the court's ruling in Aitken, the award for various littoral and riparian rights is increased.

Total award for littoral and riparian rights is $287,997 ($3.6 million in today's dollars). The court says that "there is evidence that all of these properties will be thereby damaged to an extent of three-fourths to nine-tenths of their values. When the lake is destroyed, the surrounding country will be converted into a desert and their properties will become valueless."

 

1941 Mono Basin diversions begin
  With the construction of the Mono Basin extension complete (begun during the Aitken Case), and the diversion permits granted in June 1940 by the Division of Water Resources (the agency could not see a way to prevent it), Grant Lake Reservoir starts filling in December 1940, and the first water leaves the Mono Basin in April of 1941.

 

1947-1982 Mono Lake shrinks
   Between 1941 and 1947, a wet period keeps Mono Lake from dropping, despite diversions. Then it begins to drop, and at a much greater rate after 1970 when the second barrel of the aqueduct is completed. Between 1947 and 1982, Mono Lake drops 45 vertical feet, loses half its volume, doubles in salinity, and exposes 18,000 acres of lakebed (relicted land). These relicted lands belong to the public. Tufa towers are exposed and become a scenic attraction.

 

1974 SWRCB grants DWP water rights licenses
  The California State Water Resources Control Board converts DWP's water rights permits to water rights licenses.

 

January 1, 1982 Mono Lake Tufa State Reserve created
  At the Mono Lake Committee's urging, the State Legislature passes a law creating the Mono Lake Tufa State Reserve under lease from the State Lands Commission. The lease expires June 30, 2002.

1983 Public Trust Decision by the California Supreme Court

1984 Mono Basin National Forest Scenic Area created
  Passed by Congress and signed by President Reagan, a federal law creates the Mono Basin Scenic Area from 118,000 acres of BLM land and management responsibility is given to the U.S. Forest Service.

 

1985 Federal vs. State lawsuit over relicted land
  Court finds that federal land extends downslope to the lakeshore. State land is now only below non-federal (private) lands. In 1988, the California Supreme Court rules that the Forest Service has rights as a riparian owner sufficient to serve the purposes for which the federal land had been set aside.

 

1994 SWRCB issues Decision 1631
  The California State Water Resources Control Board amends L.A.'s water rights licenses and orders Mono Lake to rise to a 6392 foot management level over the next 20 years. Computer models predict the lake will rise as high as 6400 feet and will maintain an average level of 6392.6 feet. Some tufa will be inundated and toppled, but South Tufa will remain the main point of visitation to the lakeshore.
