Below Canal Road, the canal bed at Fletcher's Cove has been empty for three winters. The towpath is open, the parking lot is open and the restrooms are open. The water is the one piece missing. The National Park Service's own status table, last updated October 14, lists every pound between Lock 3 and Lock 6 as "De-watered."
This time of year that would normally be routine. Every fall the park drains the lower canal so freezing water can't damage the stone masonry, and it usually refills in early spring. This stretch is different. It has stayed dry since the end of the 2023 season. The reason starts about a mile and a half upstream of Fletcher's, at the edge of the Palisades.
The canal's water comes in at your end
According to the NPS project page, the lower five miles of the canal "work as a system." Water is diverted from the Potomac near mile marker 5 and flows downstream to Georgetown, where it empties into Rock Creek near mile 0.4. Mile 5 is the Lock 5 area, where the feeder channel, Guard Lock and Inlet Lock 1 control what enters the canal. All of them are part of the same $12.7 million rehabilitation contract, which NPS awarded in 2023.
The project has two main work zones. One is at the intake near the Palisades. The other is three-plus miles downstream in Georgetown, at Locks 1 and 2 and the historic Level 4 walls. NPS states plainly that "water will need to be lowered in the canal during the entire duration of construction," and that the canal was drained after the 2023 season and "will remain dewatered for the duration of this major infrastructure improvement project."
So the stretch beside the Palisades can't get water back on its own schedule. It refills when the inlet at its upstream end is working again and the walls at the downstream end can safely hold water. That second condition got harder this year.
A Georgetown wall changed the Palisades timeline
Work started in February 2024 and was scheduled to finish in spring 2026. In late February 2026, part of the Level 1 north wall in Georgetown partially collapsed. That wall was already a known concern and was on the repair list. The contractor had been repointing its masonry when work paused "due to unforeseen existing conditions behind the wall and a change in the repair design."
NPS lists the likely causes as saturation that adds weight to the soil behind the wall and reduces friction between the stones, vegetation growing in the wall, and freeze/thaw cycling. Freeze/thaw is the same damage the park guards against by draining the canal every winter. The first repair steps NPS described were a 3D terrestrial LIDAR scan of the remaining wall, monitoring for further movement, and diverting surface runoff away from the slope.
The revised target on the NPS page, last updated April 8, 2026, reads:
"It is anticipated that the project will last through Fall 2026, weather dependent."
The project's main canal partner now points to a later date. Georgetown Heritage, which runs the replica canal boat in Georgetown, says on its canal boat page that the boat went into dry dock after the 2023 season and that it plans to relaunch "in Spring 2027." Its refloat campaign says "in 2027 we will re-launch the boat program" and is raising money to get the boat ready, hire and train staff, and replace equipment ahead of next spring. A boat needs a full canal to float, so the nonprofit's spring plan depends on water being back in the canal by then.
Mile by mile, as of this week
Here is the Palisades stretch as the NPS current conditions page showed it on October 27.
| Milepost | Spot | Status |
|---|---|---|
| 1.1 | Capital Crescent Trail at the Potomac Aqueduct | Local detour around DC Water work |
| 3.1 | Fletcher's Cove | Parking lot, access road and restrooms open |
| 3.2 | Fletcher's Cove water faucets, upper and lower lots | On, potable |
| 4.7 | Little Falls | DC Water repair work on the Potomac Interceptor |
| 5 | Lock 5 | Parking lot closed; use Lock 6; towpath detour |
| Locks 3 to 6 | Canal prism | De-watered |
The two ends of the Palisades stretch, Lock 5 and Little Falls, are also where the active construction is.
At Lock 5, the parking area on the Clara Barton Parkway stays closed while the intake work continues. NPS points visitors to the Lock 6 lot and other lock lots along the parkway. The contract also replaces the bridge over the Inlet Lock and Lock 5, so expect a towpath detour at that spot until the work is finished.
At Little Falls Branch, where the Maryland–DC line crosses, DC Water is making an emergency repair to the Potomac Interceptor sewer. According to DC Water's October 27 traffic advisory, recent inspections moved this section up for emergency work, and crews will repair about 400 linear feet of pipe by sliplining. The utility closed one lane of the Clara Barton Parkway on October 28 to bring in equipment. The NPS planning record for the repair describes a bypass, three excavation and bypass areas, and regrading and replanting afterward. NPS says the work is outside the usual visitor areas, needs no formal closures, and leaves the Chain Bridge lot open, though crews and equipment may take up some spaces. The job is part of DC Water's 10-year, $625 million Potomac Interceptor Rehabilitation Project.
What changes as November goes on
The biggest change of the month is water at the spigot. NPS says faucets in camping areas across the park are usually turned off around mid-November so the pipes can drain and won't burst in a freeze. They come back on in spring. For now, the park's faucet list shows the taps at Fletcher's Cove's upper and lower lots, Lock 5 and Lock 10 as on and potable. On a dog walk or a run after the middle of the month, bring your own water.
Fletcher's Boathouse rentals run on a season, and the operator lists tentative dates of mid-March through the end of October. The Tackle Shack is open only while rentals are running. The cove stays a towpath access point all winter. NPS lists the parking lot, access road and restrooms as open.
If you ride the Capital Crescent Trail into Georgetown, the detour near the Potomac Aqueduct is still posted. DC Water opened a temporary route there in May 2026 at the 3500 block of Water Street NW, near the trailhead. The work zone moved south toward the river and the trail under the aqueduct moved north. NPS still listed the detour on October 27. The Georgetown site serves DC Water's Potomac River Tunnel, which the utility says will be finished in 2030. It has said the trail will stay open throughout, with several shifts around work zones, and that the site will be restored when construction ends. Expect the route at the downtown end of your ride to change more than once before then.
The dry canal, up close
An empty canal does show you things. With the prism drained from Lock 3 to Lock 6, the stonework of the locks and the canal bed is easier to see than in a normal year, when water covers it. NPS describes that masonry as the reason for the whole project: without the rehabilitation, it says, "maintaining the watered landscape would be impossible." The stated payoff is a dependable water system for the lower five miles and canal boat rides in Georgetown again.
For questions about the project, NPS directs the public to park headquarters at 301-739-4200. The October 27 conditions page is the best place to check before you head down to Fletcher's. Once water comes back from Lock 5 to Georgetown, it will show there first.
Living close to the towpath is one of the Palisades' most practical advantages, and which access point is nearest changes from one street to the next.
