It's been two years since a floating guidewall at Wilson Lock and Dam on the Tennessee River system was sunk in 80 feet of water by Hurricane Ida, creating a bottleneck at the lock. Average lock processing time has also risen to about seven hours, with outliers of 10 hours, according to analysis by the Tennessee Valley Authority and the Corps of Engineers presented at the recent Tennessee River Valley Association meeting. Downbound lockages can only take place during daylight hours, a problem that compounds as winter approaches and the days shorten. Tows have waited up to 48 hours to transit. |
