Established in 1954, the Lake Wah-Wash-Kesh Conservation Association is a not-for-profit association of cottagers and residents on Lake Wahwashkesh, Ontario, Canada.


Wahwashkesh Lake is the largest lake in the Parry Sound District with 1,721 hectares (4,253 acres) of surface area and over 106 km of shoreline. Approximately 30% of the shoreline property is Crown Land. The lake is comprised of two distinct basins: (1) the north basin or Top Lake is the smaller of the two, and (2) the south basin is the Big Lake. Wahwashkesh is part of the Magnetawan River System, and the lake is renowned for an extremely severe spring freshet with the lake levels often rising 3 to 4 meters above the concrete weir at the outlet of the river.


The lake has a diverse fishery with over 12 species of sport fish, including naturally recruited Lake Trout. In addition, Wahwashkesh is famous for its Atlantic Coastal Plain Flora. The lake ranks in the top five of all lakes in Ontario for such flora, which the Natural Heritage Leagueopens in new window and the World Wildlife Fund documented extensively in a 1989 study.
