North Carolina added the creek to its 2002 Clean Water Act (CWA) section 303(d) list of impaired waters. Using CWA section 319 and state funding, Madison County Soil and Water Conservation District installed best management practices (BMPs) including livestock exclu- sion fencing, alternative watering facilities, pastureland management and riparian buffer plantings. Water quality improved, and North Carolina removed a 2.6-mile segment of Little Ivy Creek from its CWA section 303(d) list of impaired waters in 2008. Problem Little Ivy Creek, in Madison County, North Carolina, is a subwatershed of the larger Ivy River watershed in the Upper French Broad River Basin. Nonpoint source pollution has plagued the 60,000-acre Ivy River watershed for years. Contaminants include fecal coliform, nutrients and sediment. Biological monitoring on Little Ivy Creek in 2002 showed a score of fair, which failed to support the creek's aquatic life designated use. As a result, North Carolina added Little Ivy Creek to its CWA section 303(d) list for impaired waters in 2002. Project Highlights Community partners came together to combat the fecal coliform bacteria and sedimentation prob- lems identified by North Carolina Division of Water Quality in the watershed. This multi-project effort focused primarily on installing agricultural BMPs. To date, partners have installed four projects using CWA section 319 funds in the Little Ivy Creek and Ivy River watersheds. Partners installed more than 48,000 linear feet of livestock exclusion fencing to keep livestock out of the stream and reduce erosion (Figure 1). Project participants also installed 170 alternative watering facilities (Figure 2). One farmer adopted pasture and hay management plans, protecting an additional 530 acres of natural area. Additional BMPs funded by CWA section 319 grants helped develop a farm access road, 30 acres of riparian buffer and 25 feed/ waste management structures (Table 1). Figure 1. This fence prevents livestock from accessing Little Ivy Creek. Figure 2. This alternative water source allows livestock to drink without entering Little Ivy Creek. ------- Table 1.

North Carolina developed the North Carolina Index of Biological Integrity (NCIBI) to assess a stream's biological integrity by examining the structure and health of the fish community. NCIBI incorporates information about species richness and composition, trophic conditions, and fish abundance and condition. The NCIBI effectively summarizes all classes of factors that influence aquatic faunal communities such as water quality, energy source, habitat quality, flow regime and biotic interactions. The North Carolina Division of Water Quality breaks the Little Ivy Creek watershed into two main segments hosting one macroinvertebrate and one fish sampling station. At the most recent sampling interval in June 2007, segment 6-96-10a received a good rating for fish, and segment 6-96-10b received a good-fair rating for both macroinvertebrate and fish (Table 2). These data indicate marked biological improvement and evidence of macroinvertebrate habitat recovery in Little Ivy Creek. On the basis of these data, the North Carolina Division of Water Quality removed the 2.6-mile segment from the state's CWA section 303(d) list of impaired waters in 2008. Table 2.
