Registration is now open for a close-up look at a major construction project.

The U.S. Army Corps of Engineers will host a tour of Lower Monumental Dam on Jan. 26 to allow people to see progress inside the dam's navigation lock as workers replace the 700-ton lock gate, repair a portion of the north concrete wall and conduct other maintenance.

The dam's lock is closed to vessel traffic through March 13 to accommodate the work.

People interested in attending should contact the Corps' Walla Walla District office by 4 p.m. on Monday to register and receive detailed driving directions to the dam and parking locations, as most areas adjacent to the dam are occupied to accommodate on-site construction activities.

People can also visit the District's Web site at and click on the event flier to register or call 527-7300 or 527-7700. Names and contact information of each person going on the tour will be needed so that people can be contacted if severe weather requires the event to be rescheduled.

Visitors 18 years and older will need photo identification to enter the dam gate. People will not be allowed to bring in purses, bags, backpacks, cell phones, briefcases and similar items into secure areas of the dam. Those items cannot be checked in with the security guards and should be left in visitors' vehicles.

People will be allowed bring cameras, but no camera bags, inside the dam gate to take photographs. Visitor access at the dam is subject to change without notice.

Visitors will need to wear clothing appropriate for a construction work site and sturdy, closed-toe shoes. Weather conditions are frequently colder at the river, so people should plan to bring appropriate outerwear such as coats, hats and gloves.
