Dam reservoirs can strongly influence the spatial distribution of sediment pollution by microplastics (MP). The Villerest reservoir (Loire River, 36 km long) is a good candidate to study the relationship between MP pollution and hydrosedimentary processes. Sediments were collected from the dam-controlled river section and from 3 km downstream. Geomorphological and sedimentological analyses were performed and microplastics were analysed using µFTIR imaging (polymer identification for particle sizes ≥ 25 µm). This paper highlights strong MP levels (on an order of 10
