Bathymetry
Bathymetric data for Falling Creek Reservoir and Beaverdam Reservoir (Vinton, VA, USA) were estimated following standard methods (e.g., Wahl and Vermeyen 1998). Both reservoirs are owned and operated as primary and secondary drinking water supplies, respectively, by the Western Virginia Water Authority (WVWA). The data were collected using an Acoustic Doppler Current Profiler (ADCP; RD Instruments, San Diego, CA, USA) operated from a moving boat when both reservoirs were at full pond: ~9.3 m for Falling Creek Reservoir and ~13.5 m for Beaverdam Reservoir. Global positioning system (GPS) data were collected simultaneously with the ADCP data collection over multiple transects across both waterbodies. Data from Falling Creek Reservoir and Carvins Cove Reservoir were collected in summer/fall 2012 and data from Beaverdam Reservoir were collected in July 2014. The ADCP and GPS data were processed using WinRiver II software (RD Instruments). To determine hypsometric contours, summary statistics were generated using the Surface Volume (3D Analyst) tool in the 3D Analyst Toolbox in ArcGIS (Esri, Redlands, CA, USA). The data are presented as hypsometric relationships of surface area and volume for 0.3-1.0 m depth intervals in the two reservoirs, as well as in spatially-explicit TIN files and shapefiles.
Watershed
Watershed area was determined using the StreamStats basin delineation tool provided by the United States Geological Survey (USGS; https://streamstats.usgs.gov/ss/).
