The Lake Cities Chamber of Commerce is an independent nonprofit organization devoted to the growth and retention of businesses in the Lake Cities area.
The Lake Cities Library was established to enhance the educational and cultural opportunities of the public in general by providing equal access to library facilities, library books, and related library services in Denton County. In 2015, the Lake Cities Library came under the umbrella of the City of Lake Dallas and became the Lake Dallas Public Library. The Town of Shady Shores partners with the City of Lake Dallas in the funding of the library.
