Snake, Columbia River Dams to Open

(Andy Porter) Tour participants look over the edge of Lower Monumental Dam's cavernous navigation lock during a tour Wednesday. It was a rare opportunity to see the structure almost completely empty of water. The dams on the Columbia and Snake rivers will open for barge traffic soon. Locks were closed for several months during repairs. As Correspondent Anna King reports, barge traffic plays a big role in the Northwest economy.

Barges carry nearly $2 billion worth of cargo a year, plying the waters from the mouth of the Columbia River clear up into Idaho. So it was a big deal when the system shut down for major repairs.

Some of the dams and their locks are more than 60 years old and were corroding. At The Dalles, John Day and Lower Monumental dams the downstream lock gates had to be replaced.

Scott Clemons is a spokesman for the Portland District of the Army Corps of Engineers.

Scott Clemons: "Although we understand the impact of these outage is having on our navigation stakeholders, at least we are able to contain that impact to one 14 or 15 week period, rather than have to do a series of outages over the next few years to get all of those gates replaced."

Companies that rely on the Columbia and Snake rivers have been pushing cargo by truck and rail during the outage. All of the closed dams should be back in business by the end of March.
