Water velocities were measured along planned survey lines, which were generally perpendicular to the shoreline and spaced 100 meters apart, over an approximately 2.3-mile section of nearshore Lake Erie on June 10-12, 2019 (survey 1), and August 19-21, 2019 (survey 2), using a 1200 kHz acoustic Doppler current profiler (ADCP). The data were geo-referenced with an integrated global navigation satellite system (GNSS) smart antenna with submeter accuracy. The ADCP and GNSS antenna were mounted on a marine survey vessel, and data were collected as the survey vessel traversed the lake along planned survey lines. There was a total of 43 survey lines which typically started about 50 meters offshore and ended 500 meters offshore, and the survey lines covered the area around the mouth of Euclid Creek, Villa Angela Beach, Wildwood Marina, and the Easterly Wastewater Treatment Plant. There were either one or two transects of data collected per line. Data collection software integrated and stored the velocity and position data from the ADCP and GNSS antenna in real time. Data were processed using the Velocity Mapping Toolbox (Parsons and others, 2013) to derive temporally and spatially averaged water velocity values. These velocity measurements were collected over the course of six total days, three in early summer (survey 1) and three in late summer (survey 2), to characterize circulation, mixing, and transport patterns in nearshore Lake Erie in the vicinity of Euclid Creek and Villa Angela Beach.
