We cannot completely eliminate risk, but we can reduce and manage risk. Risk is the likelihood an event such as an excessive rainfall will occur, how the dam performs, and the consequences of failure, with loss of life the paramount concern.
High flood waters from rain cause water levels close to overtopping the gates at Beaver Lake. These operational interim risk reduction measures (IRRMs) decrease the amount of time that water will threaten inundation of the catwalk and hoist machinery. These IRRMs are also estimated to reduce the population at risk by an average of 1,000 people per day.
