STATISTICS for the RIDEAU CANAL

Lock Dimensions (1)41 metres/134 feet long by 10 metres/33 feet wide
Available Water Depth (2)1.5 metres/5.0 feet (minimum)
Minimum Bridge Clearance (3)6.7 metres/22.0 feet (minimum)
Total Locks (Kingston - Ottawa)45 (47 including the 2 locks on the Tay Canal)
Total Lockstations23 (24 including Beveridges on the Tay Canal)
       See "How the Locks Are Counted" below
Total Distance (Kingston - Ottawa) (4)202 kilometres/125.6 miles
Total Distance of Artificial Channels19 kilometres/12 miles
Lift - ascending Ottawa to Upper Rideau Lake83.8 metres/275 feet (in 31 locks)
Lift - descending Upper Rideau to Kingston50.6 metres/166.2 feet (in 14 locks)
Maximum Size of Vessel (5)27.4 m/90 ft. length, 7.9m/26 ft. width, 6.7m/22ft height
Transit Time (one way)4 to 6 days
Maximum Depth of Water100.3 metres (329 feet)




(1) This is the full length of the lock from the point of the upper sill to the point of the lower sill. The lock is actually 124 feet (37.8 m) long in the chamber, measured from the point of the lower sill to the face of the breastwork. The lower gates require 13 feet (4.0 m) of room for their swing, so a vessel must be less than 111 feet (33.8 m) long. Since the walls of the lock slope inwards, the internal width at the lower navigation water level in the locks is 31.5 feet (9.6 m).

(2) Normally the locks are maintained with a draught of 1.7 metres (5.5 feet). However even the 5 foot minimum is subject to water availability and all vessels with a draught of over 1.2 metres (4 feet) should contact the Rideau Canal Office of Parks Canada prior to traversing the canal.

(3) This is the minimum fixed bridge clearance on the Rideau Canal proper. On the Tay Canal, the Craig Street fixed bridge, at 2.1 metres/7 feet limits boats going right into downtown Perth (larger boats can tie up at Last Duel Park near downtown).

(4) Distances reflect the Rideau Canal proper. The Tay Canal, which is connected to the Rideau, extends from Lower Rideau Lake to Perth, a distance of 10.0 kilometres (6.2 miles). Two locks (Beveridges #33 & Beveridges #34) raise boats a total of 7.0 metres (22.9 feet) into the Tay Canal.

(5) The Canal used to allow boats with a length of 33.5 metres (110 feet) and a width of 9.1 metres (30 feet) width to traverse the system. If your vessel is less than these dimensions, but greater than the maximum shown in the chart, contact the Rideau Canal Office of Parks Canada.


How the Locks Are Counted

When the canal was opened in May, 1832, there were 47 masonry locks that provided navigation from Kingston to Ottawa. In reality, only 46 locks actually provided the navigation since one of the two locks at Hogs Back was (and still is) a guard lock (a flood guard, it doesn't provide any lift). But that is picking nits, so we'll leave the count at 47. In the late 1880s, two locks (Beveridges) were constructed at the entrance to the Tay Canal. Although not part of the Rideau Canal proper, they are administered by the Rideau Canal Office - so although the number of locks required for Kingston to Ottawa navigation didn't change, administratively, 2 more locks were added (total 49). In the 1970s, a new single lock (29a) replaced the flight of 3 Smiths Falls Combined locks. This reduced the actual number of Kingston to Ottawa navigation locks to 45 and the total locks administered by the Rideau Canal Office to 47. This is the situation today.

In terms of Lockstations, the present day Kingston to Ottawa navigation lockstations number 23 - they are: Ottawa (8 locks in flight), Hartwells (2 locks in flight), Hogs Back (1 lift lock, 1 guard lock), Black Rapids (1 lock), Long Island (3 locks in flight), Burritts Rapids (1 lock), Nicholsons (2 detached locks), Clowes (1 lock), Merrickville (3 detached locks), Kilmarnock (1 lock), Edmonds (1 lock), Old Slys (2 locks in flight), Smiths Falls Combined (1 lock), Smiths Falls Detached (1 lock), Poonamalie (1 lock), Narrows (1 lock), Newboro (1 lock), Chaffeys (1 lock), Davis (1 lock), Jones Falls (3 locks in flight, 1 detached), Upper Brewers (2 locks in flight), Lower Brewers (1 lock), Kingston Mills (3 locks in flight, 1 detached). The lift statistics for those locks can be seen in the next section.

The Rideau Canal Office quotes 24 lockstations since they are counting in the Beveridges Lockstation (2 detached locks) of the Tay Canal.
