Английская Википедия:Dominique River
Шаблон:Infobox river The Dominique River (Шаблон:Lang-fr) is a river in the Côte-Nord region of Quebec, Canada. It empties into the Gulf of Saint Lawrence.
Location
The Dominique river runs from north to south for Шаблон:Convert with a vertical drop of Шаблон:Convert. It has one important tributary, the Foins River (Hay River), which drains the southeast of the basin.Шаблон:Sfn The mouth of the river is in the municipality of Port-Cartier in the Sept-Rivières Regional County Municipality.Шаблон:Sfn At its mouth in the city of Port-Cartier the river converges with an arm of the Aux Rochers River in the Rivière-aux-Rochers Park. A trail in the park leads to the Rivière Dominique waterfall.Шаблон:Sfn
The origin of the name, which was made official on 5 December 1968, is not known.Шаблон:Sfn
Basin
The Dominique River basin is oriented from north to south, about Шаблон:Convert long and no more than Шаблон:Convert wide.Шаблон:Sfn It covers Шаблон:Convert. It lies between the basins of the Aux Rochers River to the west and the Sainte-Marguerite River to the east.Шаблон:Sfn The river basin is in the Sept-Rivières Regional County Municipality, divided between the unorganized territory of Lac-Walker (65.8%) and the town of Port-Cartier (34.2%).Шаблон:Sfn Part of the river basin is in the Port-Cartier–Sept-Îles Wildlife Reserve (Réserve faunique Port-Cartier–Sept-Îles).Шаблон:Sfn Part is in the proposed Lake Pasteur Biodiversity Reserve.Шаблон:Sfn
Terrain
The northern part of the Dominique River basin is on a deeply dissected rocky plateau in which slopes can rise by Шаблон:Convert. The highest point is Шаблон:Convert in the north of the basin. The piedmont region extends for Шаблон:Convert between the plateau and the coastal plain. It is formed of rounded rocky hills up to Шаблон:Convert high. The coastal plain is a strip of fairly flat land about Шаблон:Convert wide that gradually slopes down to sea level from Шаблон:Convert in the north.Шаблон:Sfn
The bedrock is dominated by magmatic rocks, deformed to some extent, of migmatite, granitoid rocks and granitic gneiss. The plateau and piedmont area include vast areas where the bedrock is exposed. In other places there is glacial till of up to Шаблон:Convert in depth, and in the main valleys there are large glaciofluvial sediments. In the coastal plain the Goldthwait Sea deposited large amounts of clay and silt sediment as it followed the retreat of the glaciers after the last ice age. As the land rebounded from the weight of the ice, the sea retreated and the marine sediments were covered by coarser sandy estuarine and deltaic sediments.Шаблон:Sfn
Hydrology
Waterbodies cover 5.72% of the Dominique River basin. The main lakes are Lake Morin at Шаблон:Convert and Little Lake Anguille at Шаблон:Convert. Ombrotrophic peatlands cover 6.15% of the basin, mostly on the coastal plain where the flat relief and fine sediments retain the water.Шаблон:Sfn The rivers and streams follow angular courses dictated by fractures in the hard bedrock. Upstream the rivers follow rather rectilinear courses through narrow valleys, but downstream they meander slightly through the loose deposits of the coastal plain. The annual average flow at the Dominique River mouth is estimated at Шаблон:Convert, varying during the year from Шаблон:Convert.Шаблон:Sfn
Environment
The Pentecôte weather station, Шаблон:Convert to the southwest of the river mouth, records an average annual temperature of Шаблон:Convert and annual average rainfall of Шаблон:Convert.Шаблон:Sfn A map of the ecological regions of Quebec shows the upper and central Dominique River in sub-regions 6j-T and 6m-T of the east spruce/moss subdomain, and the lower part in sub-region 5g-T of the eastern fir/white birch subdomain..Шаблон:Sfn On the coastal plain the forest cover is dominated by stands of balsam fir (Abies balsamea), white spruce (Picea glauca) and paper birch (Betula papyrifera), with lesser numbers of jack pine (Pinus banksiana), larch and trembling aspen (Populus tremuloides). Further inland in the spruce-moss region the forest cover is dominated by black spruce (Picea mariana), with balsam fir and, to a lesser extent, hardwoods such as paper birch, trembling aspen and balsam poplar (Populus balsamifera). Fish species are American eel (Anguilla rostrata) and brook trout (Salvelinus fontinalis). There are rainbow smelt (Osmerus mordax) at the mouth of the river. The Dominique River is not recognized as an Atlantic salmon river. Шаблон:Sfn
Conservation
The watershed is almost entirely contained in the Port-Cartier–Sept-Îles Wildlife Reserve. This reserve, with a total area of Шаблон:Convert, covers Шаблон:Convert of the Dominique River basin, or about 87.5%. The proposed Lake Pasteur Biodiversity Reserve extends into the west of the watershed. It is a protected area under IUCN category III, established in 2003. The proposed reserve covers a total area of Шаблон:Convert of which Шаблон:Convert are in the Dominique watershed, covering 18.0% of its area including Lake Morin and Little Lake Anguille. On the Gulf of St. Lawrence the river basin adjoins the Port-Cartier West Waterfowl Concentration Area (IUCN category VI).Шаблон:Sfn
