Lake Opataca is part of a group of lakes at the head of the Assinica River. Forestry is the main economic activity of the sector. Recreational tourism activities come second.

The nearest forest road is located at 61.3 kilometres (38.1 mi) south-east of the lake, the road skirting Mount Opémisca from the north; this road joins Southbound on route 113 connecting Lebel-sur-Quévillon to Chibougamau and the Canadian National Railway.

The surface of Opataca Lake is usually frozen from early November to mid-May, however, safe ice circulation is generally mid-November to mid-April.

Geography

The hydrographic slopes near Lake Assinica are:

• North side: Savournin Lake, Broadback River, Labeau Lake, Frotet Lake, Troilus Lake;
• East side: Cachisca Lake, Opataca Lake, Mistassini Lake;
• South side: Comencho Lake, Chibougamau River, Brock River West;
• West side: Lafargue Lake, Capichigamau Lake.

With a surface area of 93 km², lake Assinica has a complex shape, with innumerable bays, peninsulas and a hundred islands. Many wetlands are located nearby, especially on the east side of the lake and partly on the west side. Lake Assinica is connected on the south side to Caplan Lake. Lookout Hill (top at 459 metres (1,506 ft)) is located to the south. Another peak reached 513 metres (1,683 ft) in the Southwest. The lake has four large islands at its center, the longest of which reaches 5.8 kilometres (3.6 mi).

The mouth of Lake Assinica is located on the North-West side at:

• 25.6 kilometres (15.9 mi) South of the mouth of the Assinica River;
• 122.7 kilometres (76.2 mi) east of the mouth of Evans Lake;
• 264.7 kilometres (164.5 mi) east of the mouth of the Broadback River;
• 86.4 kilometres (53.7 mi) west of Mistassini Lake;
• 95.2 kilometres (59.2 mi) north-west of downtown Chibougamau.

Its emissary is the Assinica River, which flows a priori to the west, then to the north, to the south bank of the Broadback River where it empties.

Toponymy

The term "Assinica" has been assigned by the Commission de toponymie du Québec to the lake, the river and the Wildlife Reserve.

Of Cree origin, the term "Assinica" derives from the term "Asinikaw", whose roots are "asini, pierre and kaw" (verbal suffix equivalent to the verb "to be" in French), meaning "filled with stones".

The old map documents indicate that prior to 1932 the term applied to a set of lakes on the same hydrographic slope. Today, Assinica now only refers to the most westerly hydrographic entity. The spelling of the place name Assinica has long been spelled "Assinika".

Covering an area of 8,885 km², the Assinica Wildlife Refuge encircles the lake.

The toponym lac Assinica was formalized on December 5, 1968, at the Commission de toponymie du Québec.
