The ULM Special Collections Department has many of the Griffin Studio negatives of the 1932 flood. They are all online at the Louisiana Digital Library site and on the ULM Library catalog. One of the more interesting flood pictures (to me) shows the river side view from the back of the buildings on South Grand Street.

You can see the Endom and Railroad bridges, along with the back of the Bank building. Neat!
