Matamec Ecological Reserve, Ecological reserve in Sept-Rivières Regional County Municipality, Canada.

Matamec Ecological Reserve protects the entire drainage basin of the Matamec River, about 25 km east of Sept-Îles on Quebec's Côte-Nord. The reserve covers the river valley and its tributaries, safeguarding a complete watershed typical of the region. The name Matamec means "trout" in Innu.

The area began attracting scientific research from the Woods Hole Oceanographic Institution starting in the 1960s, with studies on salmon and trout populations. These investigations between 1966 and 1984 provided key findings about the fish communities in this region.

The name Matamec comes from the Innu language and means trout, showing how indigenous peoples have long understood the importance of this water-filled land. Today, the reserve carries this heritage in its name and in the fish species that still thrive in its rivers.

Access to the reserve is restricted and requires advance permission from Quebec's Ministry of Environment due to strict conservation rules. Visitors should arrange authorization well ahead of time before planning their visit to this protected area.

The reserve protects the entire Matamec River watershed, a drainage basin typical of the Côte-Nord. The Quebec government has announced plans to extend the reserve to the upper part of the basin, so the protected area may grow beyond its current limits.
