The original dam at this location was constructed in 1909. The new Horseshoe Lake Dam will respect the historic look of the site and have a life expectancy of more than 80 years. Phase one of the project included the construction of two brand new piers and one full sluice on the west side of the dam, as well as improved pedestrian access and an employee parking area to improve access for Parks Canada dam operators.Twelve Mile Lake Dam

Twelve Mile Lake Dam is located on the Gull River between Minden and Carnarvon, Ontario. The dam controls water levels on Twelve Mile and Boshkung Lakes, and releases flow into Mountain Lake. Le barrage du lac Twelve Mile est situé sur la rivière Gull, entre Minden et Carnarvon, en Ontario. Il permet de contrôler le niveau d’eau des lacs Twelve Mile et Boshkung, et rejette les eaux dans le lac Mountain. The new dam will have an expected service life of over 100 years and will meet current safety codes and standards.As part of the project, the bridge upstream of the dam will be removed due to its deteriorating condition. The bridge was previously a part of the road network in the area before being decommissioned and transferred to Parks Canada. Its removal will facilitate construction while improving hydraulic efficiency and visitor safety.

The Red Pine Lake Dam was originally built prior to 1878, and has seen many changes and improvements over the years. The current timber crib dam, constructed in 1972 downstream of Kennesis Lake, has a wooden deck with one sluice. The new dam has been designed for two sluices spanning the same width, and its longevity will be increased by utilizing concrete construction with a metal deck. The new dam will be located 14m upstream of the current dam as a result of the underlying bedrock conditions.
Access to the Red Pine Lake Dam is by water or all-terrain vehicle. This adds a challenging element to modern construction. To accommodate this, portions of the upstream river will be dredged to allow access for a construction barge.
