I wanted to expand and continue discussion on the threats and opportunities of the Clinch River Environmental Health. My intent is to not invoke negative information. I would like to promote and continue thoughtful discussion on how to improve conservation of the Clinch River and its resources.

I believe this is an issue that greatly affects the Eastern Edge of the Cumberland Plateau that drains in to the Clinch River Watershed. There are many beautiful streams in the Briceville, Devonia, New River, etc. areas that are crystal clear. However; they virtually have not aquatic life because they are too acidic.• Cumberland Plateau (68a) tablelands and open low mountains are about 1000 feet higher than the Eastern Highland Rim (71g) to the west, and receive slightly more precipitation with cooler annual temperatures than the surrounding lower-elevation ecoregions. The plateau surface is less dissected with lower relief compared to the Cumberland Mountains (69d) or the Plateau Escarpment (68c). Elevations are generally 1200-2000 feet, with the Crab Orchard Mountains reaching over 3000 feet. Pennsylvanian-age conglomerate, sandstone, siltstone, and shale are covered by well-drained, acid soils of low fertility. Bituminous coal that has been extensively surface and underground mined underlies the region. Acidification of first and second order streams is common. Stream siltation and mine spoil bedload deposits continue as long-term problems in these headwater systems. Pockets of severe acid mine drainage persist.
Almost 30 percent of the Lower Clinch River Watershed’s stream miles are listed as impaired by the state of Tennessee due to excessive nutrients, pathogens, siltation, alteration of streamside vegetation, low dissolved oxygen, thermal modifications, and contaminants such as PCBs, mercury, and chlordane.I do think the USDA/EPA & local community should continue to address the water quality issues of Coal Creek others that flow in to the Clinch. There have been some great improvements to the shoreline stabilization in Coal Creek thanks to CRTU and others...http://www.coalcreekaml.com/BANKstabLINKpage.htm. However; I think the issue of flood waters invigorating and transporting acidic sediment continues to impair the ph and clarity levels of the water entering the Clinch River at the Coal Creek Tributary.Sub-Watershed
