Welcome to Combined Locks
Bienvenue à l'écluse combinée
This lockstation is one link in the chain of rivers, lakes and waterway structures that make up the Rideau Canal. Built under the direction of the British military between 1826 and 1832 to serve as a supply route, the canal is an outstanding example of 19th century ingenuity in the fields of construction and engineering. A large number of original canal structures are still in existence today.
Here at Combined Locks, old and new technology stand side by side. The original flight of three locks was completed in 1831. These were replaced by a single automated lock in 1974 when a fixed bridge was constructed over the canal to accommodate increasing automobile traffic. The old locks, while not operational, have been preserved for viewing. By crossing the locks and following the pathway beneath the bridge you will find another piece of the lockstation's past, a defensible lockmaster's house constructed in 1841.
The Rideau Canal is part of Canada's family of National Historic Sites. It is maintained and operated by Parks Canada.
At Smiths Falls, the Rideau River descends almost 11 metres in less than 1/2 kilometre. To make that drop
navigable, canal engineers designed an upper, detached lock connected to a long basin and three lower locks emptying into the next reach. A waste weir and a 7-metre-high stone arch dam were built on the north side of the basin to control the water level.

Ici, à l'écluse combinée, l'ancien et le moderne se côtoient. L'échelle de trois écluses originale, terminée en 1831, a été remplacée par une unique écluse automatisée en 1974, lorsqu'un pont fixe a été érigé au-dessue du canal pour accommoder la circulation automobile de plus en plus dense. Les anciennes écluses ont été préservées, bien qu'elles ne servent plus. En traversant les écluses et en suivant la piste sous le pont, vous trouverez
en autre vestige du passé du poste d'éclusage : la résidence fortifiée du maître éclusier, bâtie en 1841.Le Canal-Rideau, dont l'entretien et l'exploitation sont assurés par Parcs Canada, fait partie de la grande famille des lieux historiques nationaux du Canada.
À Smiths Falls, la rivière Rideau descend de presque 11 mètres sur moins d'un demi-kilomètre. Pour rendre cette dénivellation navigable, les ingénieurs du canal ont conçu en amont une écluse détachée reliée à un long bassin et, en aval, trois écluses se déversant dans le bief suivant. Un déversoir et un barrage-voûte en pierre de 7 mètres de hauteur on été construits sur la rive nord du bassin pour contrôler le niveau de l'eau.
