FAQs Regarding Woody Debris and Navigation

The SCDNR often receives calls from the public regarding the removal of woody debris from rivers to allow for unimpeded navigation. The SCDNR does not regulate or permit the removal of woody debris nor have statutory authority to implement the removal of woody debris; however, the SCDNR would like to provide a balanced view regarding woody debris removal in the state’s rivers.

Best Management Practices for Woody Debris Removal for Navigation

The State navigable waters should remain navigable for recreational use and enjoyment, but the maintenance of the waterways should not have a negative impact on the aquatic resources and the recreational fishery that SCDNR manages for citizens to enjoy. Large woody debris (LWD) is an important part of an aquatic ecosystem, providing habitat diversity for invertebrates, crayfish and fish. The deposition of woody debris and large logs along the channel edges often provide the most productive fish habitat in rivers, so SCDNR recommends that when trees are cleared to allow navigation that the following best management practices for the aquatic resources are considered:

Logging Operations and Woody Debris

If logging or timbering operations have caused tree material, logs or limbs, to enter the river, then the SC Forestry Commission should be notified; call 803-896-8800. The SC Forestry Commission will investigate, determine if logging/timber harvests are the source of the problem and require removal of the material at the expense of the logger and/or landowner.
