Cypress Lake

Cypress Lake is a 2-acre swamp-like lake in the heart of the University of Louisiana at Lafayette campus that started as a prehistoric bison 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 Ragin' Cajuns football stadium, officially named Cajun Field.
