title: Berthelot Lake
text: # Berthelot Lake
  
  Berthelot Lake is a freshwater body of Berthelot Township, in the Senneterre territory, in La Vallée-de-l'Or Regional County Municipality (RCM), in the administrative region of Abitibi-Témiscamingue, in the province of Quebec, in Canada.
  
  Forestry is the main economic activity of the sector. Its surface is generally frozen from the beginning of December to the end of April.
  
  The hydrographic slope of Lake Berthelot is difficult to access as it does not have a nearby forest road. Only the road R0808 passes far north side, south of Maserès Lake; and a branch of this route beginning northwest of Faillon Lake serves the South Sector between the Mégiscane River and the Canadian National Railway.
  
  ## Geography
  
  Lake Berthelot gets its supplies on the North-East side by the Mégiscane River; on the north side, by the Macho River; and on the south side by the Berthelot River (Mégiscane River).
