Reservoirs In Flood Stage

A lake is defined to be in flood stage and shows up on this map when the most recent instantaneous water level is above flood space lower bound which is conservation pool elevation for water supply reservoirs and dead pool elevation for exclusively flood control reservoirs.

Flood height percent is defined as the ratio of water level above flood pool lower bound to flood space available between flood pool lower and upper bounds expressed as percentage. The flood pool lower bound is conservation pool elevation for water supply reservoirs and dead pool elevation for exclusively flood control reservoirs. Flood pool upper bound is the maximum design water level, or dam top when this level is not available.
