Depth average velocity of select Rock Outcrops of the St. Croix River, May 2021
This dataset is a digital surface of depth-averaged flow velocities for six sites where known rock structures exist in the St. Croix River. Acoustic Doppler Current Profilers (ADCP) are used to measure how fast water is moving across an entire water column. The ADCP measures water currents with sound, and the resulting flow information will be used for investigating the use of hydroacoustic technologies for quantifying habitat for imperiled mussels Spectaclecase (Margaritifera monodonta) and Salamander (Simpsonaias ambigua) typically associated with rock structures (e.g., wing dams, revetment) in rivers. River current velocities were collected using a SonTek RiverSurveyor© M9 for all six sites. All hydroacoustic data, including flow velocities were collected in early May of 2021, and the flow mosaics are provided in GeoTiff format.
