Kentucky Lock is located in Grand Rivers, Ky., at Tennessee River mile 22.4. Army Corps of Engineers Nashville District operates and maintains the lock at the Tennessee Valley Authority project. Kentucky Lock is the lower gateway to more than 700 miles of navigable waters in the Tennessee River Basin. The access it affords to the Barkley Canal connects the Tennessee with more than 300 miles of wat

er in the Cumberland River Basin. Due to geological conditions in the area, more than half of the completed structure is submerged. The depth to foundation rock is so great that, on the west abutment wall, only 90 feet of the 206 foot high structure is visible.

Big river. Big concrete. Bigger payoff.

The Pittsburgh and Nashville districts continue working hard to deliver the Kentucky Lock Addition Project near Paducah, Kentucky. As seen in the video, construction on the 52 lock wall monoliths is progressing to support the larger engineering mission of optimizing one of the Tennessee River’s busiest navigation facilities.

Right now, tows can wait 10 or more hours to lock through – but once the lock is put into operation, most tows will clear in a single lockage and save time, fuel, and bolster the economic benefit to the nation.

The downstream monoliths alone will take more than 375,000 cubic yards of concrete to build, but once complete, the facility will keep commerce moving swiftly, safely and efficiently on rivers throughout the region.

➡ Col. Nicholas Melin, commander of the U.S. Army Corps of Engineers Pittsburgh District, recently visited the Kentucky Lock Addition Project near Paducah, Kentucky, to see the engineering in action.

🚧 The mammoth upgrade sits on the Tennessee River and adds a new 1,200-foot navigation lock - nearly a quarter mile long - alongside the existing lock chamber to tackle bottlenecks at one of the most-used locks in the nation. Right now, barges can wait 10 hours or more to get through - but once complete, most tows will pass in a single lockage, cutting delays, saving fuel, and boosting the regional economy.

⚒ The crew is hard at work building 52 downstream lock monoliths, which require more than 375,000 cubic yards of concrete (that’s enough to cover 10 football fields, 10 feet deep). The Pittsburgh District is overseeing the project and working hand-in-hand with the Nashville District to bring the new lock to completion. When finished, the lock will keep commerce moving safely and swiftly for decades to come.

🎥 Check out Col. Melin’s visit and see this engineering marvel taking shape!

NASHVILLE, Tenn. – With continued heavy rainfall and rising river levels, the U.S. Army Corps of Engineers Nashville District is increasing its operational response to manage water releases and minimize flood risks along the Cumberland River and its tributaries.

The Water Management Center has activated Level 2 – Extended Hours of Operation today and will move to Level 1 – 24/7 Operations beginning tomorrow morning to closely monitor conditions and adjust dam operations as needed.

“Recent rainfall and forecasted river crests require constant monitoring and adjustments to our dam operations,” said Lt. Col. Robert Green, commander of the Nashville District. “USACE is actively monitoring water levels 24/7 to ensure systems are operating efficiently and optimally. We are working closely with our state and local partners, taking proactive steps to reduce the impact of rising water levels, balancing capacity across the system, and continuing to prioritize public safety.”

Current Water Levels & Impacts
• Cumberland River at Nashville: Forecast to crest at 35.5 feet by noon Sunday (Feb. 16). While below minor flood stage (40 ft), Riverfront Park will flood, and access points from Nissan Stadium will be inaccessible. Low-lying areas near the I-24 and I-65 bridges will also see flooding.
More details: https://water.noaa.gov/gauges/NAST1

• Red River at Port Royal: Expected to crest at 44.5 feet, which would be the third-highest flood crest on record since 1937 (compared to 49.5 ft in 2010 and 48.3 ft in 1975). Homes on Rivermont Dr, River Run, Idlewood Dr, and Wimbledon Ct may see floodwaters, and multiple roads could become impassable.
More details: https://water.noaa.gov/gauges/PORT1

• Cumberland River at Clarksville: Expected to crest at 49.5 feet at midnight Sunday into Monday. Flooding will impact agricultural and commercial properties, Riverfront Park, and roads including South Riverside Dr, North Riverside Dr, Quarry Rd, Kraft St, and Zinc Plant Rd.
More details: https://water.noaa.gov/gauges/CKVT1

• Cumberland River at Dover: Expected to crest just above minor flood stage at 67 feet by noon Monday. Roads near the river will become impassable, and nearby farmland will flood.
More details: https://water.noaa.gov/gauges/dovt1

• Other Areas of Concern:
Upper Cumberland (Williamsburg, Barbourville, Pineville, and Baxter) – Additional flooding expected.
Harpeth River near Kingston Springs – Forecast to exceed flood stage.

Dam Operations & Flood Management
To manage flood risks and balance water levels, the Corps has made several operational changes today:
• Barkley Dam – Is being operated in coordination with TVA and USACE’s Great Lakes & Ohio River Division for flood risk management on the lower Ohio River. Water is being passed now to save storage space and maximize flood reduction at Cairo IL later this week. Anticipated releases later today will be 150,000 cfs.
• Old Hickory Dam – Increasing spillway releases to manage increasing inflows from this morning’s rainfall. Releases will be at 75,000 cfs.
• Cordell Hull Dam – Increasing total releases to pass run-off from this morning’s rainfall and to prepare for additional rain this evening. Total flows will be 51,000 cfs.
• Due to the high flows through Cheatham Lock & Dam it is currently closed to navigation and is anticipated to remain closed through Tuesday at a minimum.
• Center Hill Dam – No water releases to limit flows on the Cumberland River through Carthage.
• Wolf Creek and Dale Hollow Dams – No water releases are scheduled for tomorrow to limit flows on the Cumberland River through Celina.

“When we talk about water releases in cubic feet per second, or CFS, it can be hard to grasp just how much water that really is,” said David Bogema, Nashville District’s Water Management section chief. “To put it in perspective, 1,000 CFS is roughly the amount of water that would fill an Olympic-sized swimming pool in just 25 seconds. Right now, Barkley Dam is releasing 150,000 CFS—that’s enough water to fill more than 5,900 swimming pools every minute.”

Heavy rain overnight and into Sunday morning will continue to impact water levels, particularly in the Barkley, Cheatham, Old Hickory, and Cordell Hull basins.

Public Safety Reminders
Unregulated or uncontrolled streams and tributaries in the Cumberland River Basin can pose significant flood risks, especially during heavy rainfall and extreme weather events. Unlike regulated reservoirs, these waterways lack flood-control infrastructure to manage rising water levels.

Flash flooding is a major concern in these areas, as rainfall can quickly overwhelm creeks, small rivers, and urban drainage systems, causing rapid water rises with little warning.

The USACE Nashville District monitors conditions and provides technical expertise, but local officials and residents should be especially aware of high-risk zones that lack flood storage capacity.

• Call 9-1-1 for life-threatening emergencies.
• Report flooding impacts to your county emergency management agency.
• Avoid flooded roads – just two feet of water can sweep a vehicle away.
