Long Creek Watershed
3 Tributaries
Through Dallas
Dallas sits within the Long Creek watershed, with drainage flowing through Dallas Branch and Little Long Creek tributaries before joining the South Fork Catawba River. Homes near these tributaries face elevated crawl space and basement seepage during multi-inch rain events — even outside FEMA-mapped flood zones. In March 2021, heavy rainfall raised flooding concerns along the South Fork in Gaston County with river levels expected to exceed flood thresholds.
