Long Slash Branch
Denham Springs sits entirely within the Amite River Watershed (see page 21). Within watersheds, there are smaller units, known as sub-watersheds, that can experience very different impacts during the same storm events. These impacts are based on the amount of development, the composition of the surrounding environment, and the amount of rainfall. For example, this maps shows how stormwater flows from surrounding areas into Long Slash Branch, which is a sub-watershed tributary through the heart of Denham Springs that carries runoff to the Amite River. High water levels in the Amite River can prevent Long Slash Branch from draining, flooding the area south of Spring Park and downtown Denham Springs.
