What intermediate water quality plan was adopted by the State Board in 1994?

The Bay-Delta Accord, adopted by the State Board in 1994, was a groundbreaking agreement that sought to establish a cooperative approach to managing water resources in the Sacramento-San Joaquin Delta. This plan addressed the complex interrelationship between water quality, water supply, and the ecological health of the Delta and its surrounding regions.

The Accord was significant because it recognized the need for a collaborative framework involving various stakeholders, including state and federal agencies, water users, environmental groups, and local governments. By focusing on balancing the needs of water supply with the conservation of aquatic ecosystems, the Accord aimed to improve both the quantity and quality of water in the Delta, which is vital for California's water supply and biodiversity.

In contrast, the other options pertain to different water management initiatives or plans but do not represent the specific intermediate water quality plan adopted in 1994. For instance, the California Delta Water Quality Plan and the Water Quality Control Plan for the San Francisco Bay involve regional water quality regulations but were not the focal points of the 1994 Accord. The State Water Resources Control Plan is a broader framework that encompasses various water quality and resource management strategies across California, rather than a specific agreement like the Bay-Delta Accord.
