Ghost Lake is a reservoir in Western Alberta, Canada, formed along the Bow River. It is located approximately 45km (28miles) west of the city of Calgary and immediately west of Cochrane. It has a water surface of 11.6km2 and a drainage basin of 6460km2[1] The average depth of the lake is 14.5m (47.6feet), and it reaches a maximum of 34m (112feet)
The lake lies in the foothills of the Rocky Mountains at an elevation of 1188m (3,898feet) and is lined on the north shore by Highway 1A. Trans-Canada Highway passes a short distance to the south. It was formed in 1929 with the completion of the Ghost Dam, and was developed on land leased from the Nakoda first nations by Calgary Power Ltd. The lake and dam are primarily used for power generation. The Ghost plant generates an average of 173,000 megawatt hours each year.[2] Calgary Power changed its name to TransAlta Utilities in 1981.
The lake freezes in December until approximately mid-May. Sport fish include lake trout, mountain whitefish, lake whitefish and brown trout.
Large fluctuations in water level due to power generation affect the recreational opportunities and biological productivity of the lake. The volume of water being released from the lake and the variance thereof also affect the Bow River downstream of the dam.
The location brings consistent, strong winds, which make the lake suitable for sailing and iceboating. The Ghost Lake Iceboat Club is located at Ghost Lake. Ghost Lake was also selected as the swimming venue for the inaugural Ironman Calgary 70.3. The summer village of Ghost Lake is located on the northern shore of the lake, about 3km (02miles) upstream from the dam. Only the Ghost Reservoir Provincial Recreation Area between the mouth of the Ghost River and the northeastern end of the lake, right next to the dam, provides public access to the lake.[3]
