These data are depth-averaged velocities measured by an acoustic Doppler current profiler (ADCP), as well as continuous depth-averaged velocities from a stationary location measured with an acoustic Doppler velocity meter (ADVM). These data were collected from the July 12-14, 2022, survey of the Ashtabula River near Ashtabula, Ohio. The location of the ADCP data are from approximately 1,500 feet upstream from the Bridge Street bridge to 3,000 feet upstream from the Bridge Street bridge. The ADVM data are from approximately 41° 53' 46.4"N, 80° 47' 39.5"W. ADCP data were collected using an integrated global navigation satellite system (GNSS) smart antenna with submeter accuracy. The ADCP and GNSS antenna were mounted on a boat and collected data as the boat traversed the area along planned survey lines. These survey lines were chosen to measure velocities near engineered flow control structures (root wads/rock vanes/boulder clusters/sills). There was typically one reciprocal pair (two passes) of data collected per line, and survey lines were completed once in the morning and once in the afternoon to try to cover a range of flows. These data were collected to increase understanding of flow patterns around the engineered flow control structures.
