Stream restoration

Healthy streams are an important part of sustainable urban and rural ecosystems.

Why Louisiana Streams are Important

Streams provide a number of ecosystem services including flood control, sediment retention, wildlife habitat, and human recreation.  Streams and their adjacent wetlands provide water quality benefits by filtering pollutants, regulating water temperature, and contributing to safe drinking water supplies. Streams lose these functions and services when they are modified or degraded, mainly by channel relocations, bank modifications, and excess pollution and erosion. 

Stream Restoration Techniques

Stream restoration is accomplished by identifying the problem, researching historic documentation, analyzing existing on-site and surrounding area features, and designing the stream to a natural condition to the maximum extent possible.  The stream design can be determined by studying adjacent and healthy “reference streams,” and/or by analyzing any existing stable segments of the degraded system and incorporating those features into a “natural channel design.”   During and following the construction of the stream, it is also important to monitor the stability of the channel and also to employ adaptive management practices to accommodate changes over time.   

How We Can Help

NRP has the experience and technical capacity to restore a degraded stream to a natural state by identifying the problem, assessing baseline conditions, and determining an appropriate stream design. NRP also provides services related to construction management, post construction monitoring, and implementing adaptive management practices when needed to ensure that the functions and values of the stream are restored and maintained over time.
