Bayou Corne and Grand Bayou

Parish: Assumption Parish

Bayou Corne was settled by residents hoping to take full advantage of the sportsman's paradise aspect of Louisiana living. A company, Texas Brine, mined a large cavern across the road and under the community in a salt dome to extract the salt brine. Since the cavern was too close to the salt dome edge, the edge of the salt dome collapsed and a 27+ acre sinkhole formed at the surface. The disruption of the earth also caused large quantities of natural gas to migrate to the surface and be released over a wide area, including Bayou Corne. The threat of natural gas entering the homes in Bayou Corne and continued settling of the partially collapsed dome resulted in a multi-year evacuation of the town and a drawn-out buyout process for most residents. The small community of Grand Bayou just down the road was displaced several years prior due to a similar threat from gas seeping up through the ground and collecting in homes. Some residents of Grand Bayou had relocated to Bayou Corne only to be displaced again.

This atlas is a working document developed by community members in partnership with LEAN as they work toward resolving the challenges they face. This content is under construction and continues to be refined as new data is compiled and community situations evolve. Please excuse any errors or omissions. It is our hope that documentation of these struggles allows a greater opportunity to learn from them and, ultimately, to improve the lives of residents across Louisiana who face these significant challenges.
