HEYBURN, Idaho - The Bureau of Reclamation will repair damaged concrete on the right side of the spillway stilling basin at Jackson Lake Dam beginning Oct. 4. During construction, the southeast side parking lot at the dam and downstream right-hand side of the river will be temporarily closed to all traffic through the end of November.
The concrete wall has significantly eroded along its base and is in need of repair. Reclamation will install steel plates on the outer wall and fill the cavity with concrete.
"Public safety is our number one concern," said Keith Brooks, civil engineer with the Upper Snake Field Office. "The parking and fishing areas will remain closed until the repair work is completed. Recreation access will still be available upstream of the dam and the north side of the river."
Jackson Lake Dam is located on the Snake River in Grand Teton National Park near Moran, Wyoming. The dam is part of the Minidoka Project and was constructed in 1911. In 1989, parts of the dam were replaced under the authority of Reclamation's Safety of Dams Act.
