Those uses specified in state or tribal water quality standards regulations for a particular segment, whether or not they are being attained. (40 CFR 131.3.(g)) Uses so designated in WQS are not meant to specify those activities or processes that the waterbody is currently able to fully support. Rather, they are the uses/processes that the state or tribe wishes the waterbody to be clean enough to support, whether or not the waterbody can, in its current conditions, fully support them.
