  ## Geography
  
  With a length of 2.1 kilometres (1.3 mi) and a maximum width of 1.3 kilometres (0.81 mi), Emerald Lake looks like a triangle with its eastern side backed by a cliff of height of 64 metres (210 ft) of the Emerald Lake Mountain whose summit reaches 240 metres (790 ft). This lake has five small bays which each take the shape of a small triangle. This lake is located entirely in the forest.
  
  Emerald Lake is located 0.8 kilometres (0.50 mi) southwest of the boundary of the Portneuf Regional Natural Park. Comprising 70 kilometres (43.50 mi), this park includes the Long lakes, Montauban, Carillon, Sept Îles, Lac en Coeur, "À l'Anguille" and some other more secondary bodies of water. This park is popular for recreational and tourist activities: hiking trails, cross-country skiing, boat launching ramp ... A 5.1 km bike path links Lac Blanc and Lac Carillon in skirting the Emerald Lake Mountain.
