Surrounded by agricultural enterprises, the lake has more than 200 homes built on its shores; a public launch provides access to non-resident visitors. The Lake Keesus Advancement Association, which has represented the residents on the lake since 1930, sponsors various social events throughout the year including fish fries, parades and holiday parties.
