DAM FAILURE

• Teton Dam Failure

• The Teton Dam, 44 miles northeast of Idaho Falls in southeastern Idaho, failed abruptly on June 5, 1976. It released nearly 300,000 acre feet of water, then flooded farmland and towns downstream with the eventual loss of 14 lives, directly or indirectly, and with a cost estimated to be nearly $1 billion.

• The purpose of this web page is to present a series of slides that show the breakup of the dam from its incipient failure stage to when the dam was completely breached. The slides were taken by Mrs. Eunice Olson of St. Anthony, Idaho, who presented the set to the Department of Earth Sciences, University of Notre Dame, to sell and to subsidize, thereby, a scholarship for undergraduate students in Earth sciences. The department, now the Department of Engineering and Geological Sciences, no longer sells the set, and has unofficially agreed that it would be a good thing to place this unique collection on the web. Attempts to contact Mrs.Olson have been unsuccessful, but nevertheless, all credit for the break up sequence of slides belongs to her.

DAM FAILURE

• Over 100 years ago, a catastrophic dam failure caused thousands of deaths and wiped out a town. Before the failure:

CASE STUDY DAM

• dam type: double curvature concrete arch buttress purpose: water supply and regulation

• height: 440 ft (134 m)

• width at foundation: 171.6 ft (52.3 m)

• length of crest: 1312 ft (400 m)

• storage capacity: 344,000 acre-ft.

CASE STUDY DAM

• The dam may also have served the people by producing electric power, but the decision was made to confine its purpose to water supply. location: near Madrid, Spain

• river: Lozoya, very close to where it joins the Jarama River

• foundation: Silurian shale

• Three joint systems pass through this foundation. construction start date: 1968

• construction end date: 1972

• first partial reservoir filling: 1970

• Maximum storage is 870 m above sea level. Filling began when the diversion tunnel was closed. It filled to 824 m above sea level in 1971 and then to 860 m in 1972. Questionnable behavior began to occur during the filling between 1971 and 1972.
