Please refer to the following article for the information you requested -- "The Lake Bistineau Salt Works and Its Civil War Operations," North Louisiana Historical Association Journal, Winter, 1970. Its by Phillip C. Cook of Ruston. I am sure that the archives at LSU-Shreveport has a copy as well as other colleges and institutions if you do not live near there. I know for a fact that the Louisiana State Archives has most back issues of this journal.

I hope this helps.
