Consequences<br />

• Inundated area will generally increase over sunny day<br />

failure<br />

• Warning time may be substantial due to monitoring<br />

during a large flood<br />

• Population at risk may be reduced due to spillway<br />

releases prior to dam failure, but need to consider if<br />

evacuated populations remain in dam breach flood plain<br />

• Loss <strong>of</strong> life may be less than for sunny day failure<br />

• Thunderstorm events may reduce reaction and warning<br />

time as compared to rain on snow flood events<br />
