Drainage network for the Greater Raleigh Area, North Carolina, 2015-2022

Metadata Updated: September 17, 2025

As part of a collaborative study with the City of Raleigh, North Carolina, the U.S. Geological Survey developed a drainage network for the Greater Raleigh Area, North Carolina using the most recent available lidar data, representing the years 2015 and 2022. This dataset includes the delineated drainage network (drainage_network.zip) and rasters representing the breached and filled digital elevation model (raleigh_dem_fil.tif), the flow accumulation raster (raleigh_d8_fac.tif), and the flow direction raster (raleigh_d8_fdr.tif). Raster files are available as Cloud Optimized GeoTIFFs, meaning they are formatted to work on the cloud or can be directly downloaded. The drainage network was delineated for all locations with an upstream drainage area greater than 0.075 square kilometers (approximately 18.5 acres) and represents perennial streams, ephemeral streams, ditches, stream buried in pipes, and artificial paths through water bodies. This dataset was developed for use in the development of a model that can remotely predict streambank erosion potential along streams in the Greater Raleigh, NC Area. However, the drainage network and supporting raster files have the potential to be used in numerous applications including watershed delineation.
