Cover thumbnailWater-quality and hydrologic data were collected during 2005 and 2008 to characterize potential source areas of nutrients and sediment within the Ledge and Holman Creek watersheds upstream from Lake Rogers in Granville County, North Carolina. Eight monitoring locations were established in all--five in Holman Creek and three in Ledge Creek--for collecting discharge and water-quality data during different streamflow conditions. Water-quality samples were collected during two sampling events in the fall of 2005 for analysis of major ions, nutrients, suspended sediment, and fecal-indicator bacteria. Water-quality samples were collected during three sampling events in the winter and spring of 2008 for analysis of nutrients and suspended sediment.
