Prien Lake was historically located along the Calcasieu River. Construction of the Calcasieu Ship Channel was completed in 1941, and included the construction of the Rose Bluff Cutoff, northwest of Prien Lake. The cufoff enabled a more efficient navigational route, and isolated Prien Lake from the direct flow of the river.
Prien Lake connects to the Calcasieu Ship Channel at three places on the north and west sides of the lake.
The lake has several wetlands which are considered sensitive environments.
The lake's designated uses, according to the Louisiana Department of Environmental Quality, are recreation, and the propagation of fish and wildlife. Prien Lake supports both recreational and commercial fishing, and fish species include croaker, redfish, speckled trout, flounder, and black drum.
Two public parks provide access to Prien Lake. Prien Lake Park has a public boat launch, parking, and picnic areas. LaFleur Park has a boat launch, beach for swimming, parking, and picnic areas.
