About Olin Pond
The primary purpose of Olin Pond is debris control. The dam is designed to catch sediment, rocks, and debris carried by flowing water — particularly important in areas prone to mudslides or heavy erosion. The dam is owned by Olin Chemical Corp. (private). It impounds the Tr-calcasieu River near Grand Cane.
The dam stands 9 feet tall and stretches 2,500 feet across, and has a maximum storage capacity of 350 acre-feet. Completed in 1954, the structure is well into its service life at over 50 years old.
This dam has a low hazard potential classification, meaning that failure would cause minimal damage, limited primarily to the dam owner's property, with no expected loss of life. The most recent inspection on record was 07/31/2005. That was over 20 years ago.
