The Teton Dam Failure: Factors Affecting the Warning and Evacuation Success
Teton Dam, the highest dam to ever fail in the United States, failed on Saturday,June 5, 1976 during initial reservoir filling. Nearly 800 homes were destroyed, 3 000 homes were damaged, 35 000 people were evacuated, and 11 people died directly or indirectly from the dam failure. The peak dam failure outflow was more than 65 000 m3 per second. Flooding eventually covered 460 km2. No formal emergency action plan or dam failure inundation maps existed for Teton Dam. The paper contains a discussion of the following topics: the specific dam failure scenario that took place; the ideal time for the failure to occur (at about noon on a warm sunny day); flood characteristics including depths, rate-of-rise, and flood wave trav-el times; destruction in the various impacted communities; the sequence of events that led to the issuance of a warning; warning time in downstream areas; methods that were used in dis-seminating the warning; reasons why people evacuated; and circumstances associated with people that died. Thoughts and observations regarding the event are presented.
