The Montreal River is a river in the Timiskaming District in the Canadian province of Ontario .

It flows 220 km from its origin in Smoothwater Lake to its confluence with Lake Timiskaming and the Ottawa River . The Montreal River is an important river for hydropower use .

River course

The Montreal River first flows 70 km northeast, then 150 km southeast to its mouth. It has its origin in Smoothwater Lake in Lady Evelyn-Smoothwater Provincial Park . Ishpatina Ridge , the highest point in Ontario, is located in the Montreal River catchment just south of Smoothwater Lake, and separates the upper reaches of the Montreal River to the northwest from the upper reaches of the Lady Evelyn River , which flows into it southeast further downstream.

The river first runs north, taking in several tributaries, and reaching the Inlet Bay of Gowganda Lake and the community of Gowganda . The river leaves the lake at Outlet Bay, passes Ontario Highway 560, and continues to flow northeast. It reaches The Forks at Matachewan and meets its largest left tributary, the West Montreal River . It flows a short distance northeast to the Fox Rapids, then turns southeast and passes the Ontario Highway 65 , then takes the right tributary Sydney Creek and the left tributary Council Creek on. Eventually he reached the Ontario Power Generation (OPG) Indian Chute Generating Station and its dam at Indian Chute Falls. The river continues its course to the southeast, reaches the community of Elk Lake , takes the right tributary Makobe River and passes the two highways 65 and 560. The river continues to flow in a southeast direction, passing the Mountain Chutes , meets at the community of Mowat Landing on the largest right tributary, the Lady Evelyn River . Then he reaches Bay Lake and the town of Latchford . The river runs parallel to Highway 65 for a stretch between Matachewan and Latchford.

The river is dammed by Latchford Dam. The Sgt. Aubrey Cosens VC Memorial Bridge on Ontario Highway 11 spans the Montreal River. Further downstream are the OPG Hound Chute Generating Station and Canadian Hydro Developers ' Ragged Chute Generating Station , each with a dam. The river passes the Fountain Falls and the Paugan Rapids . Then it reaches the reservoir of the OPG Lower Notch Generating Station . The Ontario Highway 567 then passes the river before flowing into Lake Timiskaming.

ecology

Two bird ringing stations are located in the Montreal River catchment area. One is by the Mountain Chutes, southeast of Elk Lake, and the other is by Gillies Lake, northeast of Latchford.

Hydropower plants

There are several hydroelectric plants along the Montreal River. Four of them are operated by Ontario Power Generation (OPG). In the downstream direction these are:
