Normal Streamflow Conditions
“Water quality releases for downstream control have both qualitative and quantitative requirements. The quality aspects relate to Corp’s policy and objectives to meet state water quality standards, maintain present water quality where standards are exceeded, and maintain an acceptable tailwater habitats for aquatic life... One of the most important measures of quality is quantity. At many projects authorized for water quality control, a minimum flow at some downstream control point is the primary water quality objective. Other common objectives include temperature, dissolved oxygen, and turbidity targets at downstream locations”.[1]
