Under State law, the Water Boards establish beneficial uses and water quality objectives in their water quality control plans or basin plans. Together with an antidegradation policy, these beneficial uses and water quality objectives serve as water quality standards under the Clean Water Act. In Clean Water Act parlance, state beneficial uses are called 'designated uses' and state water quality objectives are called 'criteria.' Throughout this General Order, the relevant term is used depending on the statutory scheme	high
