Owens Valley Water History

In 1913, the City of Los Angeles completed an aqueduct from Owens Valley to the City. The aqueduct had a capacity of 480 cubic feet per second (cfs). In 1970, a second aqueduct with a capacity of 300 cfs was completed and began operating, bringing the total capacity of the aqueduct system to about 780 cfs. Los Angeles' operations to supply the second aqueduct, including the pumping of groundwater in Owens Valley led to litigation by Inyo County against Los Angeles.

In a suit filed in 1972, Inyo County claimed that increased groundwater pumping was harming the environment of Owens Valley and that the practice should be analyzed in an Environmental Impact Report (EIR) in accordance with the provisions of the California Environmental Quality Act (CEQA). In 1973, the Court of Appeal for the Third Appellate District ruled that Los Angeles must prepare an EIR (32 Cal. App. 3d 795). Since 1973, Los Angeles has prepared two EIR's, one in 1976 and another in 1979, but the Appellate Court found both to be legally inadequate.

In 1980, the Inyo County Board of Supervisors drafted, and the Inyo County voters passed, a groundwater ordinance to regulate groundwater pumping in the Valley through a groundwater management plan. The plan was to be implemented by a groundwater pumping permit procedure. The ordinance created a County Water Department and a County Water Commission.

As a result of litigation commenced against the County by the City of Los Angeles and its Department, the County was directed in May 1981, by order of this Court in case number 12883, not to implement the Ordinance until a legally sufficient environmental impact report had been prepared and adopted by the County. A Final EIR was prepared, but the Final EIR was not adopted by the County.

In July 1983, as a result of litigation commenced by the City of Los Angeles and the Department, this Court in case number 12908 ruled said Ordinance unconstitutional, invalid, and preempted by law, and that the implementation of the Ordinance should be enjoined. Pursuant to stipulation of the parties, entry of an injunction and final judgment have not been entered by this Court.

In 1983, following the Superior Court's decision invalidating Inyo County's groundwater ordinance, Inyo County and Los Angeles began an attempt to develop a groundwater management plan that would settle the litigation between the parties. In April 1984, the governing bodies of Inyo County and Los Angeles approved a five (5) year interim agreement. In this interim agreement, the two parties agreed to:

  1. Settle then existing property tax litigation between Inyo County and Los Angeles;
  2. Temporarily suspend Inyo County's appeal of the Court's decision invalidating its groundwater ordinance;
  3. Temporarily suspend litigation on Inyo County's environmental suit and Court-imposed pumping restrictions by substituting jointly developed annual pumping programs;
  4. Lease Owens Valley town water systems to Inyo County, which would result in a reduction in water rates;
  5. Conduct cooperative studies, together with impartial third parties, including the United States Geological Survey (USGS);
  6. Implement certain enhancement/mitigation projects;
  7. Provide financial assistance to Inyo County from Los Angeles to cover costs of various studies and the County's water-related activities;
  8. Negotiate a long term groundwater management plan;
  9. Resume the CEQA litigation and litigation over the groundwater ordinance's validity if the parties did not develop and adopt a long term joint groundwater management plan for Owens Valley.

In December 1984, the Court of Appeal modified the Writ of Mandate that it had originally issued in 1973, to approve the five-year agreement of the parties. The Court specifically explained that the modification did not imply that a joint long term groundwater management plan would be a new project. The project was would remain as it was -- a program increasing the average rate of groundwater pumping and use (both for export and in-valley use), above a baseline rate reasonably representing the average of groundwater pumping and use (both for export and in-valley use) preceding the operation of the second aqueduct. However, the Court did allow that the command of its Writ to prepare an EIR could be met if the EIR were to be presented in conjunction with a joint long term groundwater management plan. In January 1985, this Court approved the interim agreement.

In May 1988, as a result of a joint application by Inyo County and the Department, a sixteen (16) month extension by the Court (from February 1989 to June 30, 1990) was granted to the Department for the purpose of completing studies necessary for development of a joint long term groundwater management plan and EIR. In June 1990, Los Angeles and Inyo County requested a further twelve (12) month extension to September 30, 1991. In July 1990, the Court also granted this extension. In August 1991, the Court granted a further extension to October 21, 1991.

Since 1984, certain studies budgeted at approximately five million dollars ($5,000,000.00) have been undertaken by Inyo County, Los Angeles, and USGS to learn more about the relationship between groundwater pumping and its impact on native vegetation. As part of these studies, Inyo County and the Department developed extensive information on the geohydrology, water budget, soils, and vegetation of Owens Valley. USGS compiled and analyzed the information and summarized its independent findings in a series of technical reports. These USGS reports, together with other cooperative study materials, became the technical foundation for the joint long term groundwater management plan that has been developed by the parties.

Under the joint five-year interim agreement, the two parties cooperatively developed and implemented numerous projects. These enhancement/mitigation projects range in scope from the revegetation and irrigation of certain areas to enhancement of wildlife habitats and recreation areas.

After two years of negotiations, Inyo County and Los Angeles reached a preliminary agreement on a joint long term groundwater management plan on August 1, 1989. The joint long term management plan is set forth in this Stipulation and Order. An EIR, as required of Los Angeles by the Court of Appeal's writ was presented to that Court in conjunction with the joint long term groundwater management plan. The EIR has been approved by that Court and its Writ of Mandate has been discharged
