in the basin, especially in the Second Broad River watershed. Te impacts of these efu- ents at permitted levels are generally regarded as minimal, but efects on native aquatic communities from other solutes in these and other discharges are unclear. Problems with meeting permitted discharge limits have occurred at several wastewater treatment plants in the basin (NCDWQ 2008a) . Most water quality problems that result in impaired ratings due to failure to meet water quality standards can be attributed to nonpoint source pollution. Sedimentation is the main water quality issue and stream sedimentation is severe across the Piedmont portion of the basin. Standards have been exceeded for turbidity in several stream segments in the basin (NCDWQ 2008a) . Other sources of nonpoint pollution include lawns, golf courses, and impervious surfaces. Poorly managed pasture lands contribute substantially to overall soil and streambank ero- sion. Often, riparian vegetation is minimal or nonexistent and cattle have unlimited direct access to streams which contributes to habitat degradation. Overall lack of riparian vege- tation is a widespread problem throughout the basin. Major causes of sedimentation in the basin are land clearing activities (e.g., construction, row crop agriculture, timber harvest, and mining), streambank erosion, and runof from unpaved rural roads and eroding road grades (NCDWQ 2003, 2008a) . Hydraulic and hydrologic alterations to streams, through accelerated streambank ero- sion and channel instability, contribute both directly and indirectly to habitat degra- dation. Streams have been channelized in both rural and developed areas in the basin. Development and urbanization also increase impervious surfaces and often produce drainage patterns and structures that speed the runof of rainwater and alter hydrograph curves. Property along the Broad River and Lake Lure is being developed for second homes, vacation lodges, and recreational facilities such as golf courses and horse farms. Hydrologic
