Leaburg Dam closure
Leaburg Dam

An EWEB repair project at the Leaburg Dam will require the intermittent closure of the road across the dam to all vehicle and pedestrian traffic from 8 a.m. to noon and 1 p.m. to 4 p.m., on some weekdays this spring

Why repairs are necessary

The Leaburg Dam features three roll gates, which regulate the volume of water spilled from the dam. The motor that controls the No. 2 roll gate failed in early 2012. Attempts to repair the motor in place were not successful, and it was removed in June 2012. The roll gate has remained in the "closed" or "down" position since the motor failed.

Work plan

EWEB intends to install a new motor and gear box for the roll gate in the summer of 2014. Prior to that installation, EWEB must erect a bulkhead immediately upstream of the No. 2 roll gate in order to isolate it from Leaburg Lake. The bulkhead structure will allow EWEB and its contractor to open and inspect the No. 2 roll gate safely and without causing the sudden drainage of Leaburg Lake.

Installation of the bulkhead started on Feb. 27 and could take several weeks. During the work, all access across the dam will be prohibited from 8 a.m. to noon, and from 1 p.m. to 4 p.m. Monday through Friday. During the closure periods, no vehicle or pedestrian access across the dam will be allowed.

It is likely that the first two to three weeks will require closures Monday through Friday, followed by periodic weekday access restrictions.

Emergency planning

EWEB is working in partnership with McKenzie Fire & Rescue to stage emergency vehicles on the east side of the dam to respond to emergencies during the closures. Should a life-threatening emergency occur during a closure period, EWEB and its contractor will clear the dam as quickly as possible.

Check back for more details

Once EWEB's contractor has drawn up a specific work schedule, closure dates will be shared. In addition, EWEB in late January placed a digital message board near the dam to alert those driving on Highway 126 of specific closure dates.
