Kakospictikweak River

The surrounding hydrographic slopes of the Kakospictikweak River are:

• north side: Compton Lake, Nemegousse Lake, Cawcot River, Caopatina Lake;
• east side: Dubois Lake, Normandin Lake (Normandin River), Normandin River, Buade Lake (Normandin River);
• south side: Gouin reservoir;
• west side: Mathieu River, Toussaint River, Baptiste Lake, Larouche Lake, De La Rencontre Creek, Pascagama River.

The Kakospictikweak River originates at the mouth of an unidentified lake (length: 0.5 kilometres (0.31 mi), altitude: 484 metres (1,588 ft)) located in the township of Pfister, in Eeyou Istchee James Bay (municipality). The mouth of this head lake is located at:

• 1.1 kilometres (0.68 mi) west of a mountain peak (altitude: 549 metres (1,801 ft));
• 30.4 kilometres (18.9 mi) north of the mouth of the Kakospictikweak River (confluence with Omina Lake which is connecter to Gouin Reservoir);
• 48.3 kilometres (30.0 mi) north of the village center of Obedjiwan, Quebec (located on a peninsula on the north shore of Gouin Reservoir);
• 86.1 kilometres (53.5 mi) northwest of the dam at the mouth of the Gouin Reservoir (confluence with the Saint-Maurice River);
• 141.4 kilometres (87.9 mi) north-east of the village center of Wemotaci, Quebec;
• 225.8 kilometres (140.3 mi) north-west of downtown La Tuque.[2]

From the mouth of the head lake, the course of the Kakospictikweak River flows over 44.4 kilometres (27.6 mi) according to the following segments:

Upper course of the Kakospictikweak River (segment of 22.7 kilometres (14.1 mi))

• 0.9 kilometres (0.56 mi) north-east, crossing a small unidentified lake (altitude: 470 metres (1,540 ft)) on 0.5 kilometres (0.31 mi), up to its mouth;
• 3.1 kilometres (1.9 mi) northeasterly, then southwesterly, skirting a mountain whose summit reaches 549 metres (1,801 ft) and crossing a full length unidentified lake (length: 1.6 kilometres (0.99 mi); altitude: 454 metres (1,490 ft)), to its mouth;
• 3.7 kilometres (2.3 mi) to the South-West including crossing a full length unidentified lake (length: 1.8 kilometres (1.1 mi); altitude: 447 metres (1,467 ft)), to its mouth;
• 1.3 kilometres (0.81 mi) to the southwest, to the eastern limit of Balete. Note: This limit also corresponds to the boundary between the town of La Tuque and Eeyou Istchee Baie-James (municipality);
• 5.1 kilometres (3.2 mi) southwesterly in Balete Township, including crossing Wawackeciw Lake (length: 4.1 kilometres (2.5 mi); altitude: 441 metres (1,447 ft)) on 2.3 kilometres (1.4 mi), to its mouth;
• 8.6 kilometres (5.3 mi) southerly passing on the east side of Baptiste Lake and crossing Piresiw Lake (length: 1.8 kilometres (1.1 mi); altitude: 414 metres (1,358 ft)), until its confluence which corresponds to the limit of the cantons of Balete and Mathieu. Note: Piresiw Lake receives the Kanimepiriskak Lake outlet on the west side;

Lower course of the Kakospictikweak River (segment of 21.7 kilometres (13.5 mi))

• 2.1 kilometres (1.3 mi) southeasterly by cutting a forest road to the confluence (from the north) of the Pokotciminikew River which drains five mountain lakes upstream;
• 7.3 kilometres (4.5 mi) southerly collecting the outlet of Kikikwapiskok Lake to the north shore of Kaatcipekinikatek Lake;
• 4.0 kilometres (2.5 mi) southerly across Kaatcipekinikatek Lake (elevation: 406 metres (1,332 ft)) along its entire length to the northern boundary of Mathieu Township. Note: this lake receives on the east side the discharge of the "Froid lake";
• 7.3 kilometres (4.5 mi) southwesterly, crossing over the 0.5 kilometres (0.31 mi) Natowew Lake (length: 1.4 kilometres (0.87 mi); altitude: 405 metres (1,329 ft)) to the road bridge of route 212 in the Seskatciwan Zone;
• 1.0 kilometre (0.62 mi) south forming a hook to the east, to the confluence of the Kakospictikweak River with the Gouin Reservoir.[3]

The confluence of the Kakospictikweak River with the Gouin Reservoir is located at:

• 67.5 kilometres (41.9 mi) northwest of Gouin Dam;
• 19.6 kilometres (12.2 mi) north-east of the village center of Obedjiwan, Quebec;
• 122.3 kilometres (76.0 mi) northwest of the village center of Wemotaci, Quebec;
• 209 kilometres (130 mi) north-west of downtown La Tuque;
• 317 kilometres (197 mi) northwest of the mouth of the Saint-Maurice River (confluence with the St. Lawrence River at Trois-Rivières).

The Kakospictikweak River flows into the Township of Mathieu at the bottom of a bay stretching over 5.8 kilometres (3.6 mi), e.g. the Northern part of Omina Lake on the north shore of the [[Gouin Reservoir]]; this bay is barred on the east side by a peninsula stretching southward on 5.6 kilometres (3.5 mi) and on the west side by an advanced land to a strait separating it from a large deformed island with a length of 22.9 kilometres (14.2 mi). From the mouth of this bay, the current flows south-easterly across the Gouin reservoir to the southeast, skirting several islands and passing through the Kikendatch Bay, up to the Gouin dam. From there, the current flows along the Saint-Maurice River to Trois-Rivières, where it flows into the St. Lawrence River.

The toponym "Rivière Kakospictikweak" was formalized on September 6, 1984 at the Commission de toponymie du Québec.[4]
