The North Fork of Pound River is a part of the upper reaches of the Big Sandy system. On its way to the Ohio River, the waters from North Fork flow northeast and meet the South Fork River to form the Pound River. The Pound River then flows into the Russell Fork River near Haysi, Virginia. The Russell Fork cuts through the Allegheny Mountain range to join the Levisa Fork then meets the Tug Fork at Louisa and forms the Big Sandy River.
