Cypress Lake is a 2-acre (0.8 ha) swamp-like lake in the heart of the University of Louisiana at Lafayette campus that started as a buffalo wallow. Today it is a unique university landmark that is a habitat for native irises, alligators, turtles, birds and fish, as well as a hangout for students and a point of interest for tourists visiting Lafayette, Louisiana. Cypress Lake is casually called "The Swamp," which is also the nickname of the Louisiana–Lafayette Ragin' Cajuns stadium, named Cajun Field.
