In what year was the Water Rights Decision 1485 issued by the State Board, establishing Delta water quality standards?

The Water Rights Decision 1485 was issued by the State Water Resources Control Board in 1978 to establish water quality standards for the Delta. This decision was significant as it aimed to address the deteriorating water quality in the San Francisco Bay-Delta estuary and ensure adequate flow for environmental health. The standards set forth in this decision were intended to protect fish and wildlife, highlighting the balance needed between human water needs and environmental sustainability. Establishing these standards was a critical step in California's ongoing efforts to manage and protect its water resources, especially in light of the increasing demands from urban and agricultural users.
