4.5 River Basins
site-specifc provisions to protect resource values (e.g., no new discharges or expansion of existing discharges) as described in NC Administrative codes (see 15A NCAC 02B.0225).
Table 4.44 provides information on water quality classifcations and use support ratings in the basin.
Tere are about 515 miles of streams in the Broad River Basin designated as trout (Tr) waters. Tis is not the same as the Commission’s designated public Mountain Trout Waters, which is used to designate waters that support trout and are open to public fshing. In addi- tion to the best use classifcations, NCDWR also monitors state waters to determine if they are supporting their use classifcation(s) and assign use supporting ratings. Tese ratings are published in the most recent 303(d) impaired waterbodies list (NCDWR 2014a, 2015a) . 4.5.4.3 Aquatic Species Tere are eight SGCN in the basin: two crayfshes and seven freshwater fshes. Appendix G provides a list of SGCN and other priority species for which there are knowledge gaps or management concerns. Appendix H identifes SGCN associated with aquatic communities found in this river basin. Table 4.45 identifes the SGCN found in the Broad River Basin. 4.5.4.4 Threats Affecting Aquatic Species Water quality problems are attributable to both point and nonpoint sources. Point sources are primarily wastewater treatment plants and industrial discharges. Both municipal wastewater treatment plants and industrial sources discharge colored efuents to streams
