Back to Basin Page

Description

The Lower Tar River Subbasin, hydrologic unit code (HUC) 03020103, contains the mainstem Tar River from Tarboro downstream to Washington covering ~960 square miles; this area was previously delineated as DWQ subbasins 03-03-03, 03-03-05 and 03-03-06. 

The western section of the Lower Tar River Subbasin lies within the Southeastern Plains ecoregion while the eastern portion is contained in the Middle Atlantic Coastal Plain ecoregion.  

The middle section of the subbasin includes approximately 40 river miles of the Tar River from the confluence of Swift Creek in Edgecombe County to the confluence of Conetoe Creek in Pitt County. It also includes the catchments of Cokey Swamp, Ballahack Canal, and Bynums Mill, Conetoe, Crisp, Otter, and Town Creeks. Land use is primarily forest and agriculture. Many streams in this area were channelized 35 or more years ago. The two areas with the greatest potential for impacts from agricultural nonpoint source pollution are the Cokey Swamp and Conetoe Creek catchments. Cokey Swamp also receives urban runoff from Rocky Mount.
