Rexburg is a university city in the upper Snake River valley near the site of the catastrophic 1976 Teton Dam failure, which killed 11 people and caused $2 billion in damage when the earthen dam collapsed during initial filling. The city sits downstream from several dams and in an active seismic zone near the Idaho National Laboratory. Brigham Young University-Idaho adds a large student population to emergency management considerations.
