CourseEdit

For a map showing the river course, see this reference.

The river begins at an unnamed lake in geographic Halsey Township in the Unorganized North Part of Sudbury District, and heads northeast under the Canadian Pacific Railway transcontinental main line — used at this point by Via Rail Sudbury – White River train — between the community of Nemegos to the west and Tophet to the east. It continues northeast through South Ivanhoe Lake and Halsey Lake, takes in the right tributary Kinogama River and reaches Ivanhoe Lake, substantially encompassed by Ivanhoe Lake Provincial Park.

The river has two outlets from Ivanhoe Lake: Ivanhoe River (Old Channel), the left (west) channel at the northwest of the lake, and Ivanhoe River (New Channel), the right channel (east) at the northeast.

the Old Channel passes out of the lake under Ontario Highway 101 and reaches the community of Foleyet.

the New Channel passes out of the lake controlled by the Ivanhoe Lake Dam, a barrage dam to regulate the water level on the lake and headwaters storage for hydroelectric generating stations further downstream in the drainage basin. It then takes in the right tributary Midway River, passes under the Canadian National Railway (CNR) transcontinental main line, served at this point by Via Rail Canadian trains stopping at the adjacent Foleyet railway station, takes in the right tributary Muskego River, passes again under the CNR line, and then under Highway 101 at Foleyet.

The two channels then recombine, and the river heads north, again under the CNR line, takes in the left tributary Shawmere River, passes through The Chutes, a natural water chute, and passes into the Unorganized North Part of Cochrane District at the geographic Nova Township. It turns northeast, takes in the left tributary Paypeeshek River, and reaches its mouth at the Groundhog River in geographic Montcalm Township; the Groundhog River flows via the Mattagami River and Moose River to James Bay.

EconomyEdit

Two small hydroelectric generating stations with associated dams and works have been proposed by Xeneca Power Development for sites at The Chutes and 30 kilometres (19 mi) downstream at Third Falls; the former project has completed the environmental assessment phase. The two generating stations have a proposed capacity of 8.7 MW and the projects have received feed-in-tariff contracts from the Ontario Power Authority.
