A map of the subbasin, including water quality sampling locations, is presented in Figure B- 13. Biological ratings for these sample locations are presented in Table B-13. There are no impaired streams in this subbasin. Refer to Appendix III for a complete listing of monitored waters and use support ratings. Three sites were sampled for benthos on the Upper Little River in the headwaters, the middle section and at the ambient site near its mouth. The headwater and middle sites were barely flowing, while the downstream site had good flow. The benthos ratings indicate a progressive improvement in water quality going downstream in this agricultural watershed: Good-Fair to Good to Excellent. Only the downstream site improved, compared to 1993 when it was Good. Barbeque Creek, a slow-flowing tributary of the Upper Little River, was given a Good-Fair bioclassification in 1998; the same rating it had in 1993. For more detailed information on water quality in this subbasin, refer to Basinwide Assessment Report – Cape Fear River Basin – June 1999, available from DWQ Environmental Sciences Branch at (919) 733-9960.

For information on 303(d) listing requirements and approaches, refer to Appendix IV. 13.4 Other Issues, Recommendations and Projects DWQ encourages the use of voluntary measures to prevent water quality degradation. Enforcement of sediment and erosion control laws will help to reduce impacts on area streams. Education on local water quality issues is always a useful tool to prevent water quality problems and to promote restoration efforts. For information on water quality education programs, workshops and nonpoint source agency contacts, see Appendix V. The Middle Cape Fear River Basin Association (MCFRBA) The Middle Cape Fear River Basin Association (MCFRBA) started sampling at one station in this subbasin (30 stations total) in July 1998. This data will be used to give a higher resolution picture of water quality conditions in the Upper Little River. The data will also be analyzed to support various studies and will be used with DWQ data to develop use support ratings for waters in the Cape Fear River basin during the upcoming basinwide cycle.
