The Hog's Back Falls, officially known as the Prince of Wales Falls, but rarely referred to by this name, are a series of artificial waterfalls on the Rideau River in Ottawa, Ontario, Canada. The falls are located just north of Mooney's Bay and the point where the Rideau Canal splits from the Rideau River.
Prior to the construction of the Rideau Canal, these were a gentle set of rapids originally known as Three Rock Rapids. The name Hog's Back came into use shortly before canal construction. Civil Engineer John MacTaggart, in 1827, described them as "a noted ridge of rocks, called the Hog’s Back, from the circumstances of raftsmen with their wares [timber rafts] sticking on it in coming down the stream." These rapids were about 600 metres (2 000 feet) in length with a drop of about 1.8 metres (6 feet). They were navigable by canoe; no portage was required.
Falls and lock in 1832
As part of his concept for a slackwater navigation system, Lt. Colonel John By's design for the Rideau Canal called for a large dam to be raised in this location. It would divert water from the Rideau River into the artificially-created section of the canal leading to the Ottawa locks. It would also flood the Three Island Rapids located upstream (the head of present-day Mooney's Bay marks the foot of these rapids).
The building of this dam provided one of the greatest construction challenges (it collapsed three times during construction) of the Rideau Canal, but when completed in 1831, it flooded the Rideau River at that point by 12.5 metres (41 feet). To accommodate the natural flow of the Rideau River and to prevent damage from spring flooding, a large wastewater weir was constructed. The water from this flows through a channel that was excavated in the eastern bank of the Rideau River. This created the Hog's Back Falls that we see today.
The head of the original rapids is now buried beneath the canal dam, but the lower section of the rapids can still be seen today.
This location marks where the route of the Rideau Canal leaves the Rideau River and enters a manmade canal leading to the Ottawa locks. A series of locks lowers boats from this location to the Ottawa River.
The Rideau River is a river in Eastern Ontario, Canada. The river flows north from Upper Rideau Lake and empties into the Ottawa River at the Rideau Falls in Ottawa, Ontario. Its length is 146 kilometres (91 mi).
The Rideau Canal is a 202 kilometre long canal that links the Ottawa River at Ottawa with the Cataraqui River and Lake Ontario at Kingston, Ontario, Canada. Its 46 locks raise boats from the Ottawa River 83 metres upstream along the Rideau River to the Rideau Lakes, and from there drop 50 metres downstream along the Cataraqui River to Kingston.
The Cataraqui River forms the lower portion of the Rideau Canal and drains into Lake Ontario at Kingston, Ontario. The name is taken from the original name for Kingston, Ontario; its exact meaning, however, is undetermined. Early maps showed several name variations including the Great Cataraqui River and Grand River Cataraquay. The river was once called Riviere de Frontenac, or Frontenac River. The alternate spelling "Cadaraqui" also appears in some historic texts.
The Trent–Severn Waterway is a 386-kilometre-long (240 mi) canal route connecting Lake Ontario at Trenton to Georgian Bay, Lake Huron, at Port Severn. Its major natural waterways include the Trent River, Otonabee River, Kawartha Lakes, Lake Simcoe, Lake Couchiching and Severn River. Its scenic, meandering route has been called "one of the finest interconnected systems of navigation in the world".
Bytown is the former name of Ottawa, Ontario, Canada. It was founded on September 26, 1826, incorporated as a town on January 1, 1850, and superseded by the incorporation of the City of Ottawa on January 1, 1855. The founding was marked by a sod turning, and a letter from Governor General Dalhousie which authorized Lieutenant Colonel John By to divide up the town into lots. Bytown came about as a result of the construction of the Rideau Canal and grew largely due to the Ottawa River timber trade. Bytown's first mayor was John Scott, elected in 1847.
Lieutenant-Colonel John By was an English military engineer. He is best known for having supervised the construction of the Rideau Canal and for having founded Bytown in the process. It developed and was designated as the Canadian capital, Ottawa.
The Fox–Wisconsin Waterway is a waterway formed by the Fox and Wisconsin Rivers. First used by European settlers in 1673 during the expedition of Marquette & Joliet, it was one of the principal routes used by travelers between the Great Lakes and the Mississippi River until the completion of the Illinois and Michigan Canal in 1848 and the arrival of railroads. The western terminus of the Fox–Wisconsin Waterway was at the Mississippi at Prairie du Chien, Wisconsin. It continued up the Wisconsin River about 116 miles (187 km) until reaching Portage, Wisconsin. There travelers would portage to the Upper Fox River, or eventually, use the Portage Canal. It continued about 160 miles (260 km) down the Fox River, following it through Lake Winnebago and continuing on the Lower Fox over 170 feet of falls to the eastern terminus of Green Bay.
The Gananoque River is a river in Leeds and Grenville United Counties in Eastern Ontario, Canada. The river is in the Atlantic Ocean drainage basin and is a left tributary of the Saint Lawrence River.
The Rideau Falls are two 11-metre waterfalls located in Ottawa, Ontario, Canada, where the Rideau River empties into the Ottawa River. The falls are divided by Green Island, with Ottawa's Old City Hall just to the south. To the west of the falls is the headquarters of the National Research Council while to the east are the Canada and the World Pavilion and the French Embassy. Samuel de Champlain described the falls as "...a marvelous fall...it descends a height of twenty or twenty-five fathoms with such impetuosity that it makes an arch nearly four hundred paces broad." The falls were named by the early French for their resemblance to a curtain, or rideau in French. The Rideau River was later named after the falls. The Rideau Canal was constructed to bypass these falls and the Hog's Back Falls.
The Lehigh Canal is a navigable canal that begins at the mouth of Nesquehoning Creek on the Lehigh River in the Lehigh Valley and Northeastern regions of Pennsylvania. It was built in two sections over a span of 20 years beginning in 1818. The lower section spanned the distance between Easton and present-day Jim Thorpe. In Easton, the canal met the Pennsylvania Canal's Delaware Division and Morris Canals, which allowed anthracite coal and other goods to be transported further up the U.S. East Coast. At its height, the Lehigh Canal was 72 miles (116 km) long.
Mooney's Bay Park is a public park in Ottawa, Ontario, Canada, on the Rideau River. Its main entrance is on Riverside Drive, opposite Ridgewood Avenue, but can also be accessed from Hog's Back Road.
The Carillon Canal is a National Historic Site of Canada in Saint-André-d'Argenteuil, Quebec. It preserves the historic Carillon Canal that was first built in the 1830s to facilitate travel on the Ottawa River. It is a prominent heritage site and recreation area, visited annually by 20,000 pleasure boaters and 30,000 people who use its riverside park.
The Tay Canal is the portion of the Tay River in the eastern Ontario region, providing a connection between the town of Perth and the Rideau Canal at Beveridge Bay on Lower Rideau Lake. The canal is 9.8 km (6.1 mi) in length and is operated today by Parks Canada as part of their Rideau Canal operations. At the entrance to the Tay Canal are two locks, Upper and Lower Beveridge Locks, which provide a total lift of 7.6 m (25 ft).
Hog's Back Road is a 1 km (0.62 mi) road in Ottawa, Ontario, Canada. The road connects Meadowlands Drive and Prince of Wales Drive to Riverside Drive and Brookfield Road. The road is used as the boundary line between Mooney's Bay Park and Hog's Back Park. It goes over the dam creating Mooney's Bay and Hog's Back Falls, and continues over the Hog's Back swing bridge over the Rideau Canal, to allow taller boats navigating the canal to pass. The road also runs past the spot where the Rideau Canal separates from the Rideau River.
Jones Falls Dam is a dam on the Rideau Canal located in Rideau Lakes, Leeds and Grenville United Counties, Ontario, Canada, that was built between 1828 and 1831 to tame the mile-long series of rapids and falls that flowed from Sand Lake and into the White Fish River.
Hog's Back Bridge is an asymmetrical swing bridge in Ottawa, Ontario, Canada. Located at the intersection of Mooney's Bay and the Hog's Back locks, it crosses the Rideau Canal and carries 2 lanes of Hog's Back Road and a sidewalk. The swing bridge operates from May to October when boats exceeding 9 feet (2.7 m) in height need to pass via the canal underneath.
This is the outline of the geography of the city of Ottawa, the capital of Canada. Ottawa's current borders were formed in 2001, when the former city of Ottawa amalgamated with the ten other municipalities within the former Regional Municipality of Ottawa–Carleton. Ottawa is now a single-tiered census division, home to 1,017,449 people.
The Capital Pathway, also known informally as the Bike Path, is a 220-kilometre (140 mi) recreational pathway interlinking many parks, waterways and sites in Ottawa, Ontario and Gatineau, Quebec. Most of the pathway is paved, and allows an almost continuous route through the National Capital Region.
The Ottawa River timber trade, also known as the Ottawa Valley timber trade or Ottawa River lumber trade, was the nineteenth century production of wood products by Canada on areas of the Ottawa River and the regions of the Ottawa Valley and western Quebec, destined for British and American markets. It was the major industry of the historical colonies of Upper Canada and Lower Canada and it created an entrepreneur known as a lumber baron. The trade in squared timber and later sawed lumber led to population growth and prosperity to communities in the Ottawa Valley, especially the city of Bytown. The product was chiefly red and white pine.The Ottawa River being conveniently located with access via the St. Lawrence River, was a valuable region due to its great pine forests surpassing any others nearby. The industry lasted until around 1900 as both markets and supplies decreased, it was then reoriented to the production of wood pulp which continued until the late 1990s and early 2000s.
Sand Lake is a lake on the Rideau Canal, located in the Township of Rideau Lakes, Ontario, Canada, in the ward of South Crosby. It is 891 hectares in surface area, with a maximum depth of 14.3 metres (47 ft) and a shore length of 65.5 kilometres (41 mi)
