California has been working hard to sustain its water and to supply it. Sacramento-San Joaquin Bay Delta is one of those bodies of water that is being assisted with its sustainability by receiving water from the Trinity River. Humboldt County and the United States entered into a water contract on June 19, 1959, as authorized under Section 2, Proviso 2 of Public Law 84-386, which Congress adopted on August 12, 1955. Proviso 2 conditioned the integration of the Trinity River Division into the Central Valley Project, requiring that not less than 50,000 acre-feet shall be released annually from Trinity Reservoir and made available to Humboldt County and downstream water users.
