Sydenham River (Lake Saint Clair) facts for kids

Kids Encyclopedia Facts

The Sydenham River is a river in Chatham-Kent, Lambton County and Middlesex County in southwestern Ontario, Canada, flowing southwest from its source west of London, Ontario and emptying into Lake Saint Clair. The length of the river is 165 kilometres (103 mi) and it drains a watershed of approximately 2,700 square kilometres (1,000 sq mi). The river flows through the towns of Strathroy and Wallaceburg. It was named after Lord Sydenham, governor of Canada from 1839 to 1841.

Unusual concretions, composed of calcite, can be found near this river. These are known as "kettles" because they resemble the bottom of a large kettle.

The river has been identified as a key biodiversity area.

Fish species

Because this river flows through a large agricultural area, its waters collect silt and fertilizer runoff. In spite of this, the river provides habitat for 80 fish species and 34 species of freshwater mussels; these include:

Nine mussel species considered as "endangered" nationally
  • Mudpuppy mussel (Simpsonaias ambigua)
  • Northern riffleshell (Epioblasma torulosa rangiana)
  • Rayed bean (Villosa fabalis)
  • Wavy-rayed lampmussel (Lampsilis fasciola)
  • Snuffbox (Epioblasma triquetra)
  • Round pigtoe (Pleurobema sintoxia)
  • Kidneyshell (Ptychobranchus fasciolaris)
  • Round hickorynut (Obovaria subrotunda)
  • Rainbow mussel (Villosa iris)
Two fish species and one turtle subspecies considered to be "threatened"

The Northern madtom (Noturus stigmosus), once found in the river, is considered to be "likely extirpated".
