The US Army Corps of Engineers (Corps) will delay the reopening of the Tennessee River's Wilson Lock by three weeks after high floodwater disrupted repair plans.
The Wilson Lock is now planned to reopen in mid-June or July, the Corps said this week. The lock's main chamber has been closed since September after severe cracks were found in the structure.
The Corps initiated evacuation procedures so personnel and equipment could be removed before any water entered the dewatered lock and ruined repairs after high water appeared too close to the lock's edge. The water did not crest above the temporary barrier the Corps installed to keep water out.
Delays at the lock averaged around 10 days as of 24 April, according to the Corps. Barge carriers fees have been in place for each barge that must pass through the auxiliary chamber of the lock since 25 September, when the lock first closed. Restricted barge movement placed upward pressure on fertilizer prices in surrounding areas as well.
The lock still requires structural repairs to the main chamber gates, including the replacement of the pintle components, the Corps said.
This is the fourth opening delay the Corps have issued for the Wilson Lock, with the prior opening dates being in November, then April and then in June. The Wilson Lock will enter its eighth month of repairs next month.
