The Colorado River was dammed in the 1930s to create the Highland Lakes chain, and Lake Buchanan and Inks Lake both lie within Burnet County.

Lake tourism, retirement communities, granite quarrying, ranching, and small-scale agriculture drive the Burnet County economy. The county is experiencing significant growth as Austin-area buyers seek lakefront properties and acreage within a 90-minute drive of the city.
