This paper showcases the sediment budget of a small catchment (i.e. 18.1 km²) which supplies the water input for one of the oldest lakes occurring in the Transylvania Plain. The current sediment budget allows for the analysis of the present state of the sediment flux and will form the foundation for identifying the changes in the sediment dynamics throughout the Holocene in this region. The gross erosion of land has been estimated at 3453 t km^-2yr^-1, whereas the sediment yield was 216 t km^-2yr^-1. The sediment delivery for this type of catchment is 6.24%. Our results were analysed against the regional background as compared to similar results from Romania. The SDR curve for Ştiucii Lake catchment was discussed in relation to the size of the catchment and its drainage network order (Strahler’s system).
