Calcasieu Lake is a brackish lake located in southwest Louisiana, United States, located mostly within Cameron Parish. The lake is paralleled on its west shore by Louisiana Highway 27 and is located about 17 miles south of Lake Charles, Louisiana.
The Lake is also known as Big Lake to the local population. Big Lake is well known amongst Gulf Coast anglers as a destination for large amounts of red drum (redfish) and spotted sea trout (speckled trout) as well as flounder and brown and white shrimp. It is not uncommon for anglers to catch speckled trout at seven lbs. or larger in this estuary.
On June 24, 2007, a rare albino "pink" bottlenose dolphin, Pinky, was spotted by a charter fishing-boat captain based in Lake Charles
