While relatively low compared to the South Fork's "blue-ribbon" waters, wild redband rainbow densities in the North Fork remained similar to previous surveys, and this population remains stable.
The Great Smoky Mountains National Park (GRSM) encompasses just over 2, miles of cold and coolwater streams, of which an estimated 20% are large enough to support trout populations.
