The small township consisted of 0.6 mi2 (1.7 km2) of the Macomb County portion of the village of Grosse Pointe Shores, which was part of Grosse Pointe Township and mostly located in Wayne County on the western shores of Lake Saint Clair.

On February 24, 2009, the residents of the village of Grosse Pointe Shores voted to incorporate as a city, effectively disestablishing Lake and Grosse Pointe townships when the city was formally established on April 1, 2009.

32.5% of all households were made up of individuals, and 20.0% had someone living alone who was 65 years of age or older.

There were no families and 3.8% of the population living below the poverty line, including no under eighteens and 8.7% of those over 64.

South Lake School District once served portions of the township.
