4.5.5.3 Aquatic Species Tere are 35 SGCN in the basin: two aquatic snails, two crayfsh, 18 freshwater or anadro- mous fshes, and 13 mussels. 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 4.48 identifes the SGCN found in the Cape Fear River Basin. 4.5.5.4 Threats Affecting Aquatic Species Te Cape Fear River Basin contains multiple areas of high human population density and the most populated areas are located in the Piedmont municipal regions referred to as the Triad and the Triangle (NCDWQ 2005) . Te Triad is the area encompassing Winston-Salem, Greensboro, and Highpoint, and the Triangle is the area anchored by Raleigh, Durham, and Chapel Hill. All of the major urban centers in the basin are experiencing fast growth rates. As counties in the upper basin and those along the coast experience high popula- tion growth, current capacities for drinking water and wastewater treatment will experi- ence increased demands for service that could require a corresponding increase in utility construction, water withdrawals, and treatment discharges. Comparison of water supply demand projections for municipalities in the basin with percent of projected water supply available for the 2040 planning period indicates demand from growth will utilize from 50% to 99% of available water supplies in the basin (NCDWR 2014b) .
