Motorists will be advised of alternative routes during the installation process later this summer.

The three structures include:

* Anderson Ranch Dam, on the south fork of the Boise River, about 28 miles northeast of Mountain Home, Idaho.

* Palisades Dam, on the south fork of the Snake River, about 55 miles southeast of Idaho Falls, Idaho.

* Lower Embankment of the Deer Flat Dams, an off-storage facility that impounds Lake Lowell near Nampa, Idaho.

Reclamation's long-term goal is to implement necessary corrective actions for security and safety, with minimal inconvenience to the affected public. Long-term measures to permanently address the identified security threats will be explored in collaboration with county governments, the U.S. Forest Service, and other affected agencies. These measures may include construction or improvement of alternative roads and bridges to provide vehicle access.

Alternatives will be identified and evaluated in compliance with the National Environmental Policy Act, including an opportunity for public involvement, in 2009.

Traffic will continue to cross over the dams until alternate solutions are permanently established.

"Reclamation's announcement is intended to assure the public that safety and security is a top priority," said Jerrold Gregg, Manager, Snake River Area Office.
