The following are normal flow condition hydrologic analyses relating to dams:
* [[Normal Streamflow Conditions]]
* [[Reservoir Drawdown]]


'''Normal Streamflow Conditions'''
Dam outlets should be capable of passing sufficient flows to satisfy downstream senior water rights under normal 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”.<ref name="EM 1110-2-1420" />
 
'''Reservoir Drawdown'''
 
“Where practicable, reservoir release facilities should be provided to lower the pool to a safe level adequate to correct conditions that might threaten the integrity f the dam”.<ref name="FEMA94" />
 
“Low level outlets are provided to maintain downstream flows for all levels of the reservoirs operational pool. The outlets may also serve to empty the reservoir to permit inspection, to make needed repairs, or to maintain the upstream face of the dam or other structures normally inundated”.<ref name="EM 1110-2-1420" />
