Shallow freshwater lakes near the coastline are often affected by sediment pollution. Sediment source fingerprinting (SSF) methods can aid catchment managers in identifying primary sediment sources that impact aquatic environments. This preliminary study aimed to estimate the contribution of sediment sources from the main land uses of a coastal catchment strongly influenced by wind and whose outlet is a eutrophic, endorheic lake with inflow from 11 affluents. The Barros Lake catchment (90 km2),
