Sediment is a natural part of all stream ecosystems, however excessive sediment from streambank erosion is bad for water quality. Sediment is a major pollutant in the French Broad River and its tributaries. It clogs fish gills, makes it difficult for predator fish to hunt, and destroys habitat critical for their survival. Contaminants can also bind to sediment and be transported throughout a watershed. Stream restoration projects aim to improve water quality by reducing sediment from erosion and ultimately return the stream to a healthy, functional ecosystem.
Each restoration project involves stabilizing eroding streambanks through grading and planting woody vegetation to hold the banks in place. Stream restorations often include in-water structures that create pools and riffles, which help oxygenate the water and provide a diversity of habitats for fish and other aquatic wildlife. Some situations simply call for a change in land management, such as not mowing the top of the streambank so that woody vegetation can grow.
The plant community beside a body of water is known as the riparian buffer. Native woody plants make the best riparian buffers as their deep, extensive root systems stabilize streambanks better than non-native plants like fescue grass or bamboo. Riparian buffers moderate water temperatures and provide food and cover for wildlife. They are also the first line of protection against polluted runoff entering a stream.
RiverLink has helped restore over 2.5 miles of streams in the French Broad River Watershed and continues to seek funding for future projects. If you have a stream on your property with eroding streambanks, you may benefit from a stream restoration. We also host workshops on small-scale streambank repair where dormant cuttings of native woody plants (a.k.a. live stakes) are installed. You can also get involved as a volunteer to help create healthy riparian buffers through invasive plant removal.
In 2001 RiverLink embarked on an opportunity to develop a watershed wide approach to stormwater management to improve the water quality in the Swannanoa River Watershed, through treating non-point source pollution in stormwater BMPs and two stream restorations. Read More
In 2007 RiverLink had the opportunity to work with a group of professionals and homeowners to implement a 20 acre land conservation easement and a half mile stream restoration of Robinson Creek, in South Asheville. Read More
This Stormwater Improvement Project is an effort to implement portions of the 2007 Ross Creek Master Plan. Projects were completed at St. Luke's Church and Lakewood Drive. Read More
