TOPO MAPS — NEW. Click the green 🔍 Search Maps button below the map to open a second map with a Base map row offering three choices. OSM is the standard OpenStreetMap street map. Topo shows the Canada Base Map from Natural Resources Canada with Toporama contours layered over it — the CanVec topographic data behind the printed NTS sheets, and the mapping used for hiking, hunting, canoe routes and back-country travel. Relief shows shaded relief and hypsometric tints. The search box finds any Canadian town, county or landmark by name, so you are not limited to Barrage-de-Grand-Détour.
Reading the map like a paper NTS sheet. Click Grid to overlay the UTM grid, labelled along the edges exactly as a printed topographic sheet is — at normal zoom the squares are one kilometre across, so you can read a six-figure grid reference by eye and judge distance directly off the map. Click Measure, then tap two points, to get the distance between them together with the grid bearing in degrees and mils, the true bearing, and the magnetic bearing to set on a compass — which matters in Canada, where declination runs from about 20 degrees west in Newfoundland to 20 degrees east in the Yukon.
Click 📍 My position to take a single GPS reading from your device. It marks where you are and reports your position as a UTM/MGRS grid reference as well as plain latitude and longitude — the grid reference being what Canadian search and rescue work from — with a Copy position button so you can paste it straight into a text message. It takes one reading and stops, rather than tracking continuously, to conserve your battery. Note that map tiles need cell coverage, but a GPS reading does not — your coordinates stay correct even where the map itself cannot load.
Map search is available for a limited number of queries per session to manage costs. Be specific — search precisely for best results.

Barrage-de-Grand-Détour is a locality in Matane; La Matanie, Quebec, Canada. It is classified as a small locality. Barrage-de-Grand-Détour is located at 48.8166°N, 67.5398°W.
Barrage-de-Grand-Détour holds its station upon the Rivière Matane, where the currents press against the stone with a persistent, low-frequency hum. It lies 3.0 km south-south-west of Matane, QC (from Matane, QC: bearing 193°T), and is situated 14.0 km north-west of Ruisseau-Gagnon. The weight of the water governs the mood of the Montagne à Ti-Jaune, casting long, bruised shadows that stretch toward the St. Lawrence as the sun retreats. To the east, the stillness of Lac à Luc offers a sharp contrast to the restless motion of the river, its surface often holding the pale, silver light of an early northern dusk. The terrain here rises in rugged, forested folds, where the air tastes of damp cedar and the cold, mineral clarity of the highlands. Life around Barrage-de-Grand-Détour follows the gravity of the landscape, defined by the seasonal pulse of the watershed and the enduring presence of the timbered slopes. Local industry has long drawn its purpose from the river’s strength, balancing the demands of utility with the wild, unpredictable temperament of the surrounding woods. Generations have worked in alignment with the flow of the Rivière Matane, managing the infrastructure that anchors the region while respecting the deep, quiet isolation of the Montagne à Ti-Jaune. The traditions here are sparse and functional, favoring a stoic endurance that matches the climate, where winters arrive with a sudden, absolute silence. Visitors to the vicinity of Lac à Luc find a sparse, honest beauty, one that rewards those who listen to the wind moving through the pines rather than seeking the clamor of the modern world.
Barrage-de-Grand-Détour déploie sa présence humble sur les rives du Saint-Laurent, là où le souffle marin rencontre la rudesse altière de la Montagne à Ti-Jaune. Dans cette étendue de La Matanie, l'eau occupe une place souveraine, façonnant les habitudes des habitants qui observent le courant de la Rivière Matane glisser vers l'estuaire avec une régularité apaisante. À quelques kilomètres de là, le Lac à Luc demeure un miroir paisible, niché dans le relief accidenté, loin du tumulte des grandes routes. Le climat, marqué par la proximité du fleuve, impose une lumière changeante qui transforme les textures du sol en fin de journée, dorant les pentes boisées avant que l'ombre ne s'étende sur les terres. Barrage-de-Grand-Détour conserve une allure de quiétude, une sorte de patience silencieuse héritée des anciens qui ont su lire les caprices du terrain pour y installer leurs foyers. Les gens vivent ici en harmonie avec le rythme des marées et le dégel printanier, trouvant dans la géographie austère du Québec une forme de noblesse simple. Chaque sentier qui serpente vers les hauteurs offre une perspective nouvelle sur ce paysage où la forêt et l'eau semblent s'apprivoiser sous un ciel immense.
