Water Quality
Aquatic organisms, including salmon and steelhead, can be negatively effected by water quality problems. Salmon and steelhead need cold water, high levels of dissolved oxygen (>5 mg/l), a pH close to neutral (7.0) and limited nutrient and chemical pollution.
The California State Water Resources Control Board and the North Coast Regional Water Quality Control Board (2001) recognize cold water fish as a beneficial use of water under the under the Federal Clean Water Act (CWA).
Water quality impairment in northwestern California is recognized for various water bodies through a triennial review under section 303 D of the CWA (NCRWQCB, 2001a). KRIS projects focus on factors that limit fisheries and water quality. Follow links below to discover more about the following major categories of water quality impairment.
