Alaska has adopted water quality standards (WQS) which specify the degree of degradation that may not be exceeded in a water body as a result of human activities. A number of water quality parameters have criteria values which have been adopted as regulatory standards for Birch Creek. Parameters specifically identified with criteria values include turbidity and fine sediment. Ambient water quality monitoring data has shown that segments within the upper Birch Creek drainage are water-quality limited due to turbidity.
