The footage of the flow near a fish passage at a hydropower dam presented in this dataset can be used for optical analysis of heterogeneous flow patterns. The flow was seeded with cornstarch ecofoam to facilitate the image velocimetry by means of PIV. The footage was acquired with the use of a DJI MAvic Pro UAS in a hovering mode at a 50 m altitude. The ground sampling distance of the images is 0.021 m/px, and the time interval between images in each image pair is 80 ms. The provided footage was stabilised with the help of 11 ground control points that can be seen within the field of view.
