where does the thames river start and end in ontario
Thames River (Ontario) The Thames flows west 273 kilometres (170 mi)[3] through southwestern Ontario, from the Town of Tavistock westward through the cities of Woodstock, London and Chatham to Lighthouse Cove on Lake St. Clair. Its drainage basin is 5,825 square kilometres (2,249 sq mi).[3]
Detroit River The Detroit River flows for 24 nautical miles (44 km; 28 mi) from Lake St. Clair to Lake Erie.[1] By definition, this classifies it as both a river and a strait — a strait being a narrow passageway connecting two large bodies of water,[6] which is how the river earned its name from early French settlers.[7] However, today, the Detroit River is rarely referred to as a strait, because bodies of water referred to as straits are typically much wider. The Detroit River is only 0.5 to 2.5 miles (0.80 to 4.02 km) wide. The Detroit River starts on an east to west flow but then bends and runs north to south. The deepest portion of the Detroit River is 53 feet (16 m) deep in the northern portion of the river. At its source, the river is at an elevation of 574 feet (175 m) above sea level. The river drops only three feet before entering into Lake Erie at 571 feet (174 m). As the river contains no dams and no locks, it is easily navigable by even the smallest of vessels. The watershed basin for the Detroit River is approximately 700 square miles (1,800 km2).[2] Since the river is fairly short, it has few tributaries. Its largest tributary is the River Rouge in Michigan, which is actually four times longer than the Detroit River and contains most of the basin. The only other major American tributary to the Detroit River is the much smaller Ecorse River. Tributaries on the Canadian side include Little River, Turkey Creek and the River Canard. The discharge for the Detroit River is relatively high for a river of its size. The river's average discharge is approximately 188,000 cubic feet per second (5,324 m³/s), and the river's flow is constant.[8]
