The Western Lakes Activities Association was an athletic conference for high schools located in western Wayne and southern Oakland Counties in Michigan from 1982 through 2007. The twelve schools of the WLAA merged with the Kensington Valley Conference, schools from the Oakland Activities Association, and newly opening schools to form the Kensington Lakes Activities Association in 2008.
The WLAA was formed in 1982 from the merger of the Western Six Activities Association and the Inter-Lakes League, with two schools from the Suburban Eight League. The Western Six had lost Waterford Mott to the Greater Oakland Activities Association after 1980, while the Inter-Lakes League lost White Lake Lakeland to the Kensington Valley Conference, and Pontiac Northern did not field a team for 1981, leaving the ILL with four teams. Livonia Bentley and Plymouth-Salem came from the Suburban Eight to align themselves with more local rivals, including Livonia Churchill, Livonia Stevenson, and Plymouth-Canton. The extant school from the ILL, Waterford High School, joined Waterford Mott in the Greater Oakland conference before closing in 1983.
The initial roster of 10 schools was divided into two divisions, the Western and Lakes Divisions, and remained the same until 1985, when Livonia Bentley closed, and three schools joined from the Northwest Suburban League. The 1985 alignment remained the same through the 2001-02 school year.
