Blackwater River, Camp 70 Rd, Canaan Valley Institute, Davis WV

The Blackwater River is a 34.3-mile-long (55.2 km) river in the Allegheny Mountains of eastern West Virginia, USA. Via the Black Fork, it is a principal tributary of the Cheat River. Via the Cheat, the Monongahela and the Ohio rivers, it is part of the watershed of the Mississippi River and drains an area of 142 square miles (370 km2). It is a true blackwater stream, owing to spruce and hemlock trees in its watershed, the tannins of which impart a tea or amber color to its water.

The entire course and drainage area of the Blackwater lie within Tucker County. It rises on Canaan Mountain at an elevation of 3,594 feet (1,095 m) and initially meanders north-northeastwardly through the wetlands of Canaan Valley, passing through the Canaan Valley Resort State Park and the Canaan Valley National Wildlife Refuge, and collecting two short tributaries known as the North Branch Blackwater River and the Little Blackwater River.[8] Below the mouth of the latter, the Blackwater turns west-southwestwardly for the remainder of its course. After passing the town of Davis, it falls 62 feet (19 m) over Blackwater Falls and enters the eight-mile (13 km) long Blackwater Canyon in Blackwater Falls State Park. Here it forms whitewater rapids of Class IV-V+[10] and collects the eight-mile (13 km) long North Fork Blackwater River,[11] which flows past the town of Thomas. Finally, the Blackwater joins the Dry Fork to form the Black Fork at the town of Hendricks, at an elevation of 1,690 feet (520 m).

As with other blackwater rivers, the color of West Virginia's Blackwater River results from the leaching of tannins from the decaying leaves of vegetation adjoining the stream in its upper reaches, which are slow moving. Fallen needles from stands of eastern hemlock and red spruce contribute primarily to this, although rhododendron, mountain laurel and the sphagnum bogs of Canaan Valley also contribute.[citation needed] The Blackwater is also typical in having transparent, acidic, and oligotrophic (very low nutrient) water.

Beginning in the 1880s, the Blackwater River watershed (especially the segment of the North Fork of the Blackwater River between the towns of Thomas and Douglas) suffered extreme environmental degradation due to deep mining and coke production. This was exacerbated by the surface mining activities of the 1960s and '70s,[citation needed] which brought about a severe decline in water quality due to acid mine drainage (AMD). In recent years, the limestone treatment of AMD in the Blackwater River has met with success with the effort receiving an award from the U.S. Office of Surface Mining. AMD is created when sulfite-bearing mineral strata are exposed to air and rainwater, such as when surface mining occurs. The sulfuric acid produced from the sulfite reaction can dissolve metals such as iron, aluminum, and magnesium. By 2004, the combination of acid and dissolved metals drainage had destroyed or damaged about 12,000 miles (19,300 km) of streams in Appalachia, including the Blackwater River and streams in its watershed. Restoration of the Blackwater River watershed was a costly and complex task involving two large projects. The Douglas Highwall Abandoned Mine Land Reclamation Project installed 16,000 tons (14,400 tonnes) of limestone in a "Wetland/Anoxic Limestone Drain (WALD) system" on the North Fork Blackwater River downstream of Thomas. Although the experimental WALD system did not perform as intended, and "has not generated measurable alkalinity" it did reduce the total acid and metal load in the water discharge from the abandoned mine into the river system. More successful was a project just upstream of Davis, on Beaver Creek, a tributary of the Blackwater. A six-drum water-powered limestone grinding station adds limestone slurry to the water flowing down Beaver Creek. A Swedish-designed limestone powder dosing system was also installed as backup to the drum system. The five mile (8 km) stretch of the Blackwater between the limestone station and the confluence with the North Fork has now become one of West Virginia's premiere catch and release trout streams. Canaan Valley Institute (CVI) is a nonprofit, non-advocacy organization that helps organizations identify, solve, and implement solutions to serious water issues impacting their daily lives. Our organization's technical capabilities and human resources come together to help community organizations, government agency partners, and businesses solve two of the most widespread problems in the Mid-Atlantic Highlands: streambank erosion and polluted waters caused by inadequate wastewater treatment. CVI has a wide array of services and programs and the people to assist you. We can help you identify the problem, plan ways to solve it, connect you with potential working partners, identify possible sources of financial assistance, and implement a sustainable solution suitable for your needs. Combining scientific information with the needs and desires of local organizations to develop sustainable solutions is a CVI specialty. Assistance may come from development of solutions that save property owners from damage or property loss caused by flooding. Other times we assist by identifying the sources of pollution and help to eliminate them. It's not something most people think about, but if you live in a community where access to clean water isn't a given, there is nothing more important. Visit the Our Capabilities section of our website for more information on services that CVI can provide or call toll free, 1-800-922-3601.
