The Coordinated Operating Agreement (COA) was originally signed in 1986 and defines how public and federal water projects share the water quality and environmental flows commitments imposed by regulators. The agreement provides for a periodic review to determine if updates are required taking into account the amended conditions. Following a joint review process, DWR and Reclamation agreed to an addendum to the COA, which reflects the water quality, biological advisory and hydrology provisions that have been updated since the agreement was signed. You`ll find the original chord here and the 2018 addendum is here. Today, the United States Bureau of Reclamation and the California Department of Water Resources announced a series of agreements to resolve water disputes that have angered the state for decades and to affirm cooperation between the federal and state governments to find long-term solutions to California`s major water problems. The National Water Management Authority`s Phase 1 staff proposal for tributaries of the San Joaquin River provides percentage flows of unhindered flow. Because the process is underway at the State Water Board, the parties, and in particular Governor Brown`s state administration, have also been interested in pursuing voluntary transaction agreements, such as the 1994 Bay Delta Accord. The Department of Water Resources, the Natural Resources Agency and the export and export area parties of the various flows of the system have made considerable efforts to achieve a voluntary regime that covers both flow and non-river action. Arakawa recalled that much has happened since the original 1986 agreement: changing hydrology, the North Bay Aqueduct, interconnections between the two projects, regulations, biological opinions, the Central Valley Project Improvement Act and now an update to the State Water Board`s water quality control plan.
Since August 2018, Reclamation and DWR, supported by public water authorities from almost every region of the state, have held lively discussions to review contributions from the Central Valley Project, the State Water Project and the public water authorities, which serve as voluntary conflict resolution agreements on proposed changes to the Bay Delta water quality control plan. , and to revise the common formulas as part of the 1986 Coordinated Operations Agreement.
