Columbia Lake - Environmental Reserve
is approximately 109 hectares in size along the Laurel Creek Corridor.
Laurel Creek is a perennial stream that flows through the center of the Environmental Reserve, in a southerly direction before discharging into Columbia Lake.
Natural vegetation, including small wetland areas, occurs in the riparian areas adjacent to Laurel Creek. A mixed swamp forest occurs within the environmental reserve lands to the northwest within the floodplain of Laurel Creek. The Laurel Creek Watershed Study has identified this reach of Laurel Creek (including Columbia Lake) as a year round warm water sportfish habitat.
