The Yvonne River successively crosses the townships of Marceau, Bressani and Langloiserie. Forestry is the main activity economic sector; recreational tourism activities, second.

The Yvonne River Valley is served by the R1099 forest road (North-South direction) which passes on the west side and by some roads secondary forest managed mainly for logging.

The surface of the Yvonne River is usually frozen from early November to mid-May, however safe ice circulation is usually from mid-November to mid-April.

Geography
The surrounding hydrographic slopes of the Yvonne River are:

The Yvonne River originates at the mouth of Lake Narcissus (length: 1.6 kilometres (0.99 mi); elevation: 411 metres (1,348 ft)) in the Township of Marceau (at the southern limit of the township of Bressani and near the eastern limit of the township of L'Espinay), in Eeyou Istchee Baie-James (municipality).

This source is located at:

From the mouth of Lake Narcissus (the head lake), the Yvonne River flows over 32.3 kilometres (20.1 mi) according to the following segments:

Upper course of the Yvonne River (segment of 13.3 kilometres (8.3 mi))

  • 8.3 kilometres (5.2 mi) towards the North-East, in the canton of Bressani, collecting the waters of the dump (coming from the East) of the Lac des Roches Volcaniques,

to the west shore of Lake Émélie;

  • 1.9 kilometres (1.2 mi) to the north crossing Lake Cécile (length: 2.9 kilometres (1.8 mi); altitude: 391 metres (1,283 ft)), to its mouth;
  • 1.2 kilometres (0.75 mi) northeasterly across Annette Lake (elevation: 391 metres (1,283 ft)) along its entire length to its mouth;
  • 1.9 kilometres (1.2 mi) to the northwest bypassing a peninsula (advancing westward) as it crossed Lake Yvonne (length: 4.9 kilometres (3.0 mi); elevation: 391 metres (1,283 ft)), to its mouth;

Lower River Yvonne (segment of 19.0 kilometres (11.8 mi))

  • 7.1 kilometres (4.4 mi) northeasterly to the confluence of Tusy Lake (from the east);
  • 1.0 kilometre (0.62 mi) towards the west, to the discharge (coming from the South-West) of a set of lakes including Lake Sylvie;
  • 2.1 kilometres (1.3 mi) north, to the line separating the townships of Bressani and Langloiserie;
  • 2.2 kilometres (1.4 mi) north in the township of Langloiserie, to a creek (coming from the southwest) which drains five lakes;
  • 6.6 kilometres (4.1 mi) north crossing through some swamp areas to its mouth.[2]

The Yvonne River empties onto the south shore of a bay stretching south of Surprise Lake (Roy River) from 5.6 kilometres (3.5 mi). The northeastern part of this lake is crossed by the Roy River which goes north-east to the south shore of Caopatina Lake which is crossed by the Opawica River. From there, the current of this river generally descends to the West crossing in particular the Des Vents Lake (Opawica River), the Bras Coupé Lake (Opawica River), the Doda Lake, Françoise Lake (Opawica River), Lichen Lake (Opawica River), then the North to its confluence with the Chibougamau River; this confluence is the source of the Waswanipi River.

The course flows westward through the northern portion of Lake Waswanipi, Goéland Lake and Olga Lake, before pouring into the Matagami Lake which in turn flows into the Nottaway River, a tributary of Rupert Bay (James Bay).

The confluence of the Yvonne River with the Opawica River is located at:

gollark: Yes, Lua exists and I could embed it somehow, but there are !!FUN!! challenges with that:- the API is kind of unsafe so the Rust wrappers are not great- I would also have to write a bunch of glue code to allow interacting with pages and whatever, which is especially hard as my code is asynchronous- I'd *also* have to work out a nice way to integrate scripting into the interfæce still.
gollark: No, I would build some highly accursed migration tool.
gollark: Also yes.
gollark: Yes.
gollark: Also, it is planned to and currently does store all data (except file uploads, I guess, when/if™ that is added) in a single SQLite3 database.
