The Mississippi River is a tributary of the Ottawa River in Eastern Ontario , Canada which has no relation with the Mississippi River in the United States. It is 200 kilometres (120 mi) in length from its source at Mackavoy Lake, has a drainage area of 4,450 square kilometres (1,720 sq mi), and has a mean discharge of 40 cubic metres per second (1,400 cu ft/s). There are more than 250 lakes in the watershed.
16-610: Communities along the river include the village of Lanark , the towns of Carleton Place , Mississippi Mills (including towns of Almonte and Pakenham ), and Galetta . Here it enters the Ottawa River. The origin of the river's name is likely derived from its proximity to the nearby Kichisìpi, meaning "Great River" in Anicinàbemowin, the Algonquin language. The Misi-ziibi (Big River) is a minor tributary of Kichisìpi (Ottawa River) and
32-466: A land area of 4.77 km (1.84 sq mi), it had a population density of 168.3/km (436.0/sq mi) in 2021. According to the 2001 Statistics Canada Census: Race Break Up Purdon Conservation Area The Purdon Conservation Area in the municipality of Lanark Highlands , Lanark County , in Eastern Ontario , Canada. Located near the community of Lanark , it is operated by
48-479: A rich aquatic flora over marble bedrock, and has recorded observations for the musk turtle . The river originally powered textile mills. Today, it provides hydroelectric power. Such power dams, however, have all but eliminated American eels from the river. These eels were once an abundant source of food for aboriginal populations, as well as providing a source of food for great blue herons , otters , and other animals. There are many important natural areas along
64-548: The Lanark and District Museum featuring exhibits of local history. Until the late 1990s, the major employer in the village was the Glenayr Kitten Mill, which produced clothing and offered their products at several factory outlet stores in the village. Several of the buildings are still known by their numbers (e.g. Kitten Factory #1) to local residents. The Clyde Woolen Mills was the founder of these properties. Lanark has in
80-574: The Panmure Alvar. The river has a surprising diversity of turtles, including painted turtles , snapping turtles , Blanding's turtles , musk turtles and map turtles . The last four are considered species at risk, probably because nesting beaches have been degraded by human settlement. Lanark, Ontario Lanark is an unincorporated community and former village in the municipality (and incorporated township ) of Lanark Highlands , Lanark County , in Eastern Ontario , Canada . The village
96-585: The forests had much more eastern hemlock , but this was logged out to produce bark for the tanning industry. Now, large hemlock stands are uncommon. Most forests are less than a century old. The irregular terrain of the upper watershed is produced by the remnants of an ancient mountain chain, the Grenville Mountains , which arose on the supercontinent of Rodinia more than a billion years ago. These mountains have since been eroded to mostly gneiss and marble hills, with occasional outcrops of granite. Lower in
112-481: The largest river in the area. Alternatively, the name may originate from " Mazinaa[bikinigan]-ziibi ", Algonquian for '[painted] image river', referring to the pictographs found on Mazinaw Lake , though this is by no means proven. According to the Algonquins of Ontario, the river's name is S'ni'miko'bi, or "beaver creek." From its headwaters at Mackavoy Lake to its confluence at the Ottawa River near Fitzroy Harbour ,

This highly regarded baseball tournament features 18-year-old players from across the country to play at Clyde Memorial Park. In the 2021 Census of Population conducted by Statistics Canada , Lanark had a population of 803 living in 364 of its 382 total private dwellings, a change of 3.2% from its 2016 population of 778. With
144-516: The river drops 200 metres (660 ft) in elevation. It begins on the Canadian Shield (mostly gneiss and marble), and then, after Carleton Place , flows through limestone and clay plains. At Carleton Place, there are rapids with limestone cliffs. This area supports the largest stand of hackberry trees in the region. Most of the upper landscape is temperate deciduous forest dominated by sugar maple , American beech , and red oak . At one time,
160-530: The river from Sheridans Rapids down to just past Playfairville. Here there are small populations of unusual species including Parnassia glauca (Grass-of-parnassus), Platanthera flava (Tubercled Orchid) and Spiranthes lucida (Shining Ladies'-tresses). Downstream, where the Mississippi enters the Ottawa River, there are several important shorelines and wetlands, including the Mississippi Snye, which has
176-461: The river that are important for their plant communities. The first section of interest includes the east end of Dalhousie Lake and the swamp- and marsh-lined portion of the Mississippi River from the lake almost to Sheridans Rapids. Shallow lakes and adjacent river make up the provincially significant McCullochs Mud Lake Wetland. The second portion of interest is the rocky, rapid-filled section of

#1733085557817192-529: The river. Purdon Conservation Area supports Canada's largest native colony of showy lady slipper orchids , comprising about 16,000 plants. The Carleton Place Hackberry stand, and the Innisville Wetlands, have both been mentioned above. In drier areas, there are several provincially significant alvars , limestone plains with exposed rock and many rare plants. These include the Burnt Lands Alvar and
208-467: The seasonal cycles of the river. High water periods in the spring flood large areas creating wetland soils and large areas of marsh. As water levels slowly fall, conditions suitable for swamp forests occur. This natural seasonal alternation between high and lower water levels is essential for creating the natural diversity of wetlands along the river. Upstream, in Lanark County, there are two sections of
224-558: The watershed, there are younger limestone rocks. Most of these are covered by clay deposited when this area was covered by the Champlain Sea . Occasional large wetlands occur along the river. One of the largest is the Innisville Wetlands, a provincially significant wetland that is also designated an Area of Natural and Scientific Interest . Another large wetland is the Appleton Silver Maple Swamp. These wetlands depend upon
240-483: Was finally defeated by the flood of cheap Asian textiles into North America. Jobs in the textile industry moved overseas. Logging has continued, although in a much reduced manner. Wood is harvested chiefly for the pulp industry or for firewood. In 1959 a major fire destroyed many of the main commercial structures and a number of homes in the village's centre. Most buildings were inadequately insured. Replacement buildings are highly functional in their design. The village has
256-543: Was first settled in 1820 by Scottish immigrants who named it after the town of Lanark in Scotland. In 1823 it established its first post office. It soon became a major hub of the lumbering and textile industries, both of which used the Clyde River which runs through the village, as a source of power and as a transportation route to transport logs east to the Ottawa River. The textile industry lasted for about 170 years, but
